To establish proper vehicle communication to the tablet, you need to perform the following steps:
1. Connect the VCMI device to the vehicles DLC for both communication and power source. 2. Connect the VCMI device to the tablet via BT pairing, Wi-Fi or USB connection. 3. When the above steps are completed, check the VCMI navigation button at the bottom bar on the screen, if a green BT, Wi-Fi or USB icon displays at the lower right corner, the MaxiSys Ultra Diagnostic Platform is ready to start vehicle diagnosis. 4.1.1.1 Vehicle Connection The method used to connect the VCMI device to a vehicles DLC depends on the vehicles configuration as follows:
A vehicle equipped with an On-board Diagnostics Two (OBD II) management system supplies both communication and 12-volt power through a standardized J-1962 DLC. A vehicle not equipped with an OBD II management system supplies communication through a DLC connection, and in some cases supplies 12-volt power through the cigarette lighter receptacle or a connection to the vehicle battery. OBD II Vehicle Connection This type of connection only requires the main cable without any additional adapter. To connect to an OBD II vehicle 20 1. Connect the main cables female adapter to the Vehicle Data Connector on the VCMI device, and tighten the captive screws. 2. Connect the cables 16-pin male adapter to the vehicles DLC, which is generally located under the vehicle dash. NOTE The vehicles DLC is not always located under the dash; refer to the user manual of the test vehicle for additional connection information. Non-OBD II Vehicle Connection This type of connection requires both the main cable and a required OBD I adapter for the specific vehicle being serviced. There are three possible conditions for Non-OBD II vehicle connection:
DLC connection supplies both communication and power. DLC connection supplies communication and power is to be supplied via the cigarette lighter connection. DLC connection supplies communication and power is to be supplied via connection to the vehicle battery. To connect to a Non-OBD II Vehicle 1. Connect the main cables female adapter to the Vehicle Data Connector on the VCMI device, and tighten the captive screws. 2. Locate the required OBD I adapter and connect its 9-pin jack to the main cables male adapter. 3. Connect the attached OBD I adapter to the vehicles DLC. NOTE Some adapters may have more than one adapter or may have test leads instead of an adapter. Whatever the case, make the proper connection to the vehicles DLC as required. To connect the cigarette lighter 1. Plug the DC power connector of the cigarette lighter into the DC power supply input port on the device. 2. Connect the male connector of the cigarette lighter into the vehicles cigarette lighter receptacle. To connect the clipper cable 1.

In-car software is becoming one of the leading needs for service, and updating software may be the only way to fix the following issues:
Drivability Fuel Efficiency Power Loss Fault Codes Durability of Mechanical Parts The Programming and Coding function is used to re-flash the vehicle control modules, which allows you to update the computer software of the vehicle to the latest version, 52 as well as to reprogram adaptive data for certain components after making repairs or replacements. NOTE The programming function applies only when the vehicle is connected with a VCMI or J2534 programming device, which serves as a PassThru interface to establish communication with and transfer data to the vehicles ECU. Available programming or coding operations vary by test vehicle. Only the available operations display in the tablet menu. There are two general types of programming operations:
A. Coding also known as Teach-in Program, or Component Adaptation, is used to reprogram adaptive data for vehicle control modules after repairs or replacements of vehicle parts. B. Reprogramming Operations downloads the latest version of software from the online server database is done automatically when the tablet is connected to the Internet, so there is no need to check for software updates yourself), and reprograms the newest version into the vehicles ECU. Internet access (this procedure through NOTE Ensure that the tablet is connected to a stable internet access before applying the ECU programming function, so that the tablet is able to obtain access to the manufacturers server for update service. Selecting the Programming or Coding function opens a menu of operation options that varies by make and model. Selecting a menu option either shows a programming interface or opens another menu of additional choices. Follow all screen instructions while performing the programming or coding operations. How and what information is presented on the screen vary according to the type of operation being performed. 53 4.9.1 Coding Figure 4-27 Sample Coding Screen The main section of the Coding screen displays a list of vehicle components and the coding information that mainly consists of two parts:
1. All available systems for coding are displayed on the left side, and the coding data or value on the right side. 2. The bottom line of the main section displays the functional buttons, which allows you to manipulate the operation. Check the vehicle condition and the coding information carefully, use the functional button to edit Codes for the corresponding components, tap Send when you finish editing all the items. When the operation is done, an execution status message such as Completed, Finished or Successful, may display. Tap the ESC button to exit the function. 4.9.2 Reprogramming Operation Before reprogramming begins:
It is mandatory that Ultra tablet is connected to stable WiFi network. Tablet must be connected to VCMI by USB. Tablet battery must be fully charged during module programming. Connect tablet to charger if needed. Attach battery maintainer to vehicle battery to ensure steady 13-15 voltage is 54 maintained. If reprogramming a used module, it needs to be unlocked. Do not quit the application during a module reprogramming process or will fail. Typical reprogramming operations require you to input and validate VIN number first. Tap the input box and enter the correct number, and the programming interface then displays. Figure 4-28 Sample Reprogramming Operation Screen The main section of the reprogramming interface offers information of the hardware, the current software version and the newest software versions to be programmed into the control units. A series of on-screen operational instructions will display to guide you through the programming procedure. Carefully read the on-screen information and follow the instruction to execute the programming procedure. 4.9.3 Re-flash Errors IMPORATANT When reprogramming onboard, always make sure the vehicle battery is fully charged and in good working condition. During reprogramming, the operation may fail if voltage falls below the proper operation voltage. Sometimes a failed operation can be recovered, but the failed reprogramming can also ruin the control module. We recommend connecting an external battery maintainer to the vehicle to ensure steady 12-15 voltage is maintained and a successful operation. 55 Occasionally a flash update procedure may not complete properly. Common causes of flash errors include poor cable connections between the tablet, VCMI, and vehicle, the vehicle ignition being switched off before the flash procedure is complete, or low vehicle battery voltage. the process crashes, recheck all If to assure good communications and initialize the flash procedure. The programming procedure will automatically repeat if the previous operation does not succeed. the cable connections 4.10 Generic OBD II Operations A fast-access option for OBD II/EOBD vehicle diagnosis is available on the Vehicle Menu screen. This option presents a quick way to check for DTCs, isolate the cause of an illuminated malfunction indicator lamp (MIL), check monitor status prior to emissions certification testing, verify repairs, and perform other emissions-related services. The OBD direct access option is also used for testing OBD II/EOBD compliant vehicles that are not included in the Diagnostics database. Functions of the diagnostics toolbar buttons at the top of the screen are the same as those available for specific vehicle diagnostics. See Table 4-2 Diagnostics Toolbar Buttons on page 31 for details. General Procedure To access the OBD II/EOBD diagnostics functions 1. Tap the Diagnostics application button in the MaxiSys Job Menu. The Vehicle Menu displays. 2. Tap the EOBD button. There are two options to establish communication with the vehicle. Auto Scan select it to establish communication using each protocol in order to determine which one the vehicle is broadcasting on. Protocol select it to open a submenu of various protocols. A communication protocol is a standardized way of data communication between an ECM and a diagnostic tool. Global OBD may use several different communication protocols. 3. Select a specific protocol if the Protocol option is selected. Wait for the OBD II Diagnostic Menu to appear. 56 Figure 4-29 Sample OBD II Diagnostic Menu 4. Select a function option to continue. DTC & FFD I/M Readiness Live Data O2 Sensor Monitor On-Board Monitor Component Test Vehicle Information Vehicle Status NOTE Some functions are supported only on certain vehicles. Function Descriptions This section describes the various functions of each diagnostic option:
DTC & FFD When this function is selected, the screen displays a list of Stored Codes and Pending Codes. When the Freeze Frame data of certain DTCs are available for viewing, a snowflake button will display on the right side of the DTC item. The Erase Codes function can be applied by tapping the functional button at the bottom of the screen. 57 Figure 4-30 Sample DTC & FFD Screen Stored Codes Stored codes are emission-related DTCs from the ECM of the vehicle. OBD II/EOBD Codes have a priority according to their emission severity, with higher-priority codes overwriting lower-priority ones. The priority of the code determines the illumination of the Malfunction Indicator Light (MIL) and the codes erase procedure. Manufacturers rank codes differently, so expect to see differences between vehicles. Pending Codes These are codes whose storing conditions have been met during the last drive cycle, but need to be met on two or more consecutive drive cycles before the DTC stored. The purpose of this service is to assist the service technician after a vehicle repair when diagnostic information is cleared, by reporting test results after a single driving cycle. a) If a test fails during the driving cycle, the DTC associated is reported. If the pending fault does not occur again within 40 to 80 warm-up cycles, the fault is automatically cleared from memory. b) Test results reported by this service do not necessarily indicate a faulty component or system. If test results indicate another failure after additional driving, a DTC is stored to indicate a faulty component or system, and the MIL is illuminated. Freeze Frame In most cases the stored frame is the last DTC reported. Certain DTCs, those that have a greater impact on vehicle emission, have a higher priority. In these cases, 58 DTC of the highest priority is the one for which the freeze frame records are retained. Freeze frame data includes a snapshot of critical parameter values at the time the DTC is stored. Erase Codes This option is used to clear all emission-related diagnostic data such as, DTCs, freeze frame data and specific manufacturer-enhanced data from the vehicles ECM, and resets the I/M Readiness Monitor Status for all vehicle monitors to Not Ready or Not Complete status. A confirmation screen displays when the clear codes option is selected to prevent accidental loss of data. Select Yes on the confirmation screen to continue, or No to exit. I/M Readiness This function is used to check the readiness of the monitoring system. It is an excellent function to use prior to having a vehicle inspected for compliance to a state emissions program. Selecting I/M Readiness opens a submenu with two choices:
Since DTCs Cleared displays the status of monitors since the last time the DTCs are erased. This Driving Cycle displays the status of monitors since the beginning of the current drive cycle. Live Data This function enables the display of real-time PID data from the ECU. Displayed data includes analog and digital input and output, and system status information broadcast in the vehicle data stream. Live data can be displayed in various modes, see 4.5 Live Data on page 43 for detailed information. O2 Sensor Monitor This function allows retrieval and review of recent O2 sensor monitor test results stored on the vehicles on-board computer. The O2 Sensor Monitor test function is not supported by vehicles that communicate using a controller area network (CAN). For O2 Sensor Monitor tests results of CAN-equipped vehicles, refer to On-Board Monitor. On-Board Monitor This function allows you to view the results of On-Board Monitor tests. The tests are useful after the service when a vehicles control module memory is already erased. 59 Component Test This function enables dual-direction control of the ECM so that the diagnostic tool can transmit control commands to operate the vehicle systems. This function is useful in determining how well the ECM responds to a command. Vehicle Information This function enables the display of the vehicle identification number (VIN), calibration identification number, calibration verification number (CVN), and other information of the test vehicle. Vehicle Status This function service to check the current condition of the vehicle, such as the communication protocols of OBD II modules, retrieved codes amount, and status of the Malfunction Indicator Light (MIL). 4.11 Diagnostic Report Pre-Scan and Post-Scan To perform the pre-scan and post-scan functions:

It shortens searching time, simplifies operational procedures, and directly displays the data as required. Figure 5-5 Sample TSB Screen For details, please tap the TSB icon, and you will see a file unfolded with OEM Information. The following graph is an example of cause analysis of image interference in night view system with exact TSB information, complaint, causes, remedy and relevant symptoms for the vehicle. Figure 5-6 Sample Detailed TSB Screen 5.5 Frequency of Occurrence The Frequency of Occurrence graph shows the frequencies of different faults as mileage increases. 69 Figure 5-7 Sample Frequency of Occurrence Graph Graph example: As is shown in the graph below, each fault has its changing frequency that peaks at a certain mileage. Before the mileage reaches 100k miles, the camera internal fault occurs more frequently than other fault types, with its highest frequency of 10 coming at 70k miles, while line connection fault between control module of Night View Assist system (N101) and dynamic CAN high distributor X30/28 occurs as frequently as 10 at 90k miles. As the mileage approaches 110k miles, the occurrence of the two faults drops, giving way to Night View Assist system control module fault which, after reaching 9 at 110k miles, starts to decline at the same point. Another line fault between camera (B84/2) and control module of Night View Assist (N101), poses not much threat in the previous 110k miles, but it boasts a maximum occurrence of 8 when the vehicle travels 130k miles. Similarly, the power supply fault of control module of Night View Assist (N101) becomes most worrisome at 150k miles. In conclusion, the graph provides a convenient reference to locating possible faults of the Night View Assist function in accordance with the driving mileage. 5.6 Troubleshooting Troubleshooting presents a series of diagnostic and repair steps from confirming fault symptoms to clearing the faults.

The typical service operation screen is a series of menu driven executive commands. Follow on-screen instructions to select appropriate execution options, enter correct values or data, and perform necessary actions. The application will display detailed instructions to complete selected service operations. After entering each special function, the screen will display two application choices:
Diagnosis and Hot Functions. The Diagnosis enables the reading and clearing of codes which is sometimes necessary after completing certain special functions. Hot Functions consists of sub functions of the selected special function. Figure 6-1 Sample Service Menu Several most commonly used services are described in this chapter. 6.1 Oil Reset Service Perform reset for the Engine Oil Life system, which calculates an optimal oil life change interval depending on the vehicle driving conditions and climate. The Oil Life Reminder must be reset each time the oil is changed, so the system can calculate when the next oil change is required. NOTE 1. Always reset the engine oil life to 100% after every oil change. 74 2. All required work must be carried out before the service indicators are reset. Failure to do so may result in incorrect service values and cause DTCs to be stored by the relevant control module. 3. For some vehicles, the scan tool can reset additional service lights such as maintenance cycle and service interval. On BMW vehicles for example, service resets include engine oil, spark plugs, front/rear brakes, coolant, particle filter, brake fluid, micro filter, vehicle inspection, exhaust emission inspection and vehicle checks. 6.2 Electric Parking Brake (EPB) Service This function has a multitude of usages to maintain the electronic braking system safely and effectively. The applications include deactivating and activating the brake control system, assisting with brake fluid control, opening and closing brake pads, and setting brakes after disc or pad replacement. 6.2.1 EPB Safety It can be dangerous to perform Electric Parking Brake (EPB) system maintenance, so before you begin the service work, please keep these rules in mind. Ensure that you are fully familiar with the braking system and its operation before commencing any work. The EPB control system may be required to be deactivated before carrying out any maintenance/diagnostic work on the brake system. This can be done from the tool menu. Only perform maintenance work when the vehicle is stationary and on level ground. Ensure that the EPB control system is reactivated after the maintenance work has been completed. NOTE Autel accepts no responsibility for any accident or injury arising from the maintenance of the Electric Parking Brake system. 6.3 Tire Pressure Monitoring System (TPMS) Service This function allows you to quickly look up the tire sensor IDs from the vehicles ECU, as well as to perform TPMS replacement and reset procedures after tire sensors are replaced. 75 6.4 Battery Management System (BMS) Service The Battery Management System (BMS) allows the tool to evaluate the battery charge state, monitor the close-circuit current, register the battery replacement, activate the rest state of the vehicle, and charge the battery via the diagnostic socket. NOTE 1. This function is not supported by all vehicles. 2. The sub functions and actual test screens of the BMS may vary by vehicle, please follow the on-screen instructions to make correct option selection. The vehicle may use either a sealed lead-acid battery or an AGM (Absorbed Glass Mat) battery. Lead acid battery contains liquid sulphuric acid and can spill when overturned. AGM battery (known as VRLA battery, valve regulated lead acid) also contains sulphuric acid, but the acid is contained in glass mats between terminal plates. that is recommended the replacement aftermarket battery has It the same specifications, such as capacity and type, as the exiting battery. If the original battery is replaced with a different type of battery (e.g. a lead-acid battery is replaced with an AGM battery) or a battery with a different capacity (mAh), the vehicle may require reprogramming of the new battery type, in addition to, performing the battery reset. Consult the vehicle manual for additional vehicle-specific information. 6.5 Diesel Particle Filter (DPF) Service The Diesel Particle Filter (DPF) function manages DPF regeneration, DPF component replacement teach-in and DPF teach-in after replacing the engine control unit. The ECM monitors driving style and selects a suitable time to employ regeneration. Cars driven a lot at idling speed and low load will attempt to regenerate earlier than cars driven more with higher load and speed. In order for regeneration to take place, a prolonged high exhaust temperature must be obtained. In the event of the car being driven in such a way that regeneration is not possible, i.e., frequent short journeys, a diagnostic trouble code will eventually be registered in addition to the DPF light and Check Engine indicators displaying. A service regeneration can be requested in the workshop using the diagnostic tool. Before performing a forced DPF regeneration using the tool, check the following items:
The fuel light is not on. No DPF-relevant faults are stored in system. The vehicle has the specified engine oil. The oil for diesel is not contaminated. 76 IMPORTANT Before diagnosing a problem vehicle and attempting to perform an emergency regeneration, it is important to obtain a full diagnostic log and read out relevant measured value blocks. NOTE 1. The DPF will not regenerate if the engine management light is on, or there is a faulty EGR valve. 2. The ECU must be re-adapted when replacing the DPF and when topping up the fuel additive Eolys. 3. If the vehicle needs to be driven in order to perform a DPF service, a second person is needed for the function. One person should drive the vehicle while the other person observes the screen on the Tool. Do not attempt to drive and observe the scan tool at the same time. This is dangerous and puts your life and the lives of other motors and pedestrians at risk. 6.6 Immobilizer (IMMO) Service An immobilizer is an anti-theft mechanism that prevents an automobiles engine from starting unless the correct ignition key or other device is present. This device prevents thieves from starting the car by a method known as hot wiring. Most new vehicles have an immobilizer as standard equipment. An important advantage of this system is that it doesnt require the car owner to activate it; it operates automatically. An immobilizer is considered as providing much more effective anti-theft protection than an audible alarm alone; many auto insurance companies offer lower rates for vehicles that are equipped with an immobilizer. As an anti-theft device, an immobilizer disables one of the systems needed to start a car's engine, usually the fuel supply or the ignition. This is accomplished by radio frequency identification between a transponder in the ignition key and a device called a radio frequency reader in the steering column. When the key is placed in the ignition, the transponder sends a signal with a unique identification code to the reader, which relays it to a receiver in the vehicle's computer control module. If the code is correct, the computer allows the fuel supply and ignition systems to operate and start the car. If the code is incorrect or absent, the computer disables the system, and the car will be unable to start until the correct key is placed in the ignition. The IMMO service can disable a lost vehicle key and program the replacement key fob. One or more replacement key fobs can be programmed. 77 6.7 Steering Angle Sensor (SAS) Service Steering Angle Sensor Calibration permanently stores the current steering wheel position as the straight-ahead position in the steering angle sensor EEPROM. Therefore, the front wheels and the steering wheel must be set exactly to the straight-ahead position before calibration. In addition, the vehicle identification number
(VIN) is also read from the instrument cluster and stored permanently in the steering angle sensor EEPROM. On successful completion of calibration, the steering angle sensor fault memory is automatically cleared. Calibration must always be carried out after the following operations:
Steering wheel replacement Steering angle sensor replacement Any maintenance that involves opening the connector hub from the steering angle sensor to the column Any maintenance or repair work on the steering linkage, steering gear or other related mechanism Wheel alignment or wheel track adjustment Accident repairs where damage to the steering angle sensor or assembly, or any part of the steering system may have occurred NOTE 1. Autel accepts no responsibility for any accident or injury arising from servicing the SAS system. When interpreting DTCs retrieved from the vehicle, always follow the manufacturers recommendation for repair. 2. All software screens shown in this manual are examples, actual test screens may vary by test vehicle. Pay attention to the menu titles and onscreen instructions to make correct option selections. 3. Before starting procedure, make sure vehicle has an ESC button. Look for button on dash. 78 7 Remote Programming Remote Programming Operation is a support function based on data transmission through Cloud platform, providing remote programming for solving tricky diagnostic troubles. 7.1 General Introduction Remote programming operation uses the Cloud platform to build an invisible bridge that connects the client diagnostic tablet with experts that have OEM software information.

Up to four traces, along with digital readouts of current signal values, signal status and triggering conditions, can be displayed simultaneously on the main view section screen. Each trace has two control features as X-axis and Y-axis, which enable you to adjust the oscilloscope settings to suit the particular test measurement. If multiple traces are displayed at the same time, the Y-axis for each trace is adjusted separately while the X-axis is the same for all traces. Y-axis the voltage level is recorded on the vertical. It is shown down the left side of the screen. X-axis time is presented on the horizontal. It is shown along the bottom of the screen. Measurement Overrange Indicator When the signal voltage exceeds the measurement input range, a red overrange indicator with the message Channel overrange is displayed in the top left corner of the screen displays. Exceeding the common-mode input range may cause inaccurate measurements and can lead to severe signal distortion. Figure 9-27 Sample Over-range Indicator Screen 132 Select an appropriate scale setting for the signal being sampled to avoid an overrange condition. IMPORTANT To prevent electric shock, do not exceed voltage limits between inputs. Channel Selection In the main view section, a channel has two conditions: selected and unselected. Some operations depend on the selected condition of the channel, such as voltage rulers, waveform movements, and waveform zooming. Tap the zero baseline marker or the Y-axis, which thickens to indicate the channel is selected. Figure 9-28 Sample Channel Selection 1 (Selected) Tap the zero baseline marker or the Y-axis again to exit the channel selection. 133 Figure 9-29 Sample Channel Selection 1 (Unselected) Waveform Zooming The zooming function allows you to change the size and position of a signal during or after capturing a waveform to examine it in greater details. It does not change the stored data, but the way it displays. The X-axis and Y-axis can be zoomed using your fingertips. The waveform can be zoomed during or after capturing the signal. Measurement Rulers The coordinate Rulers allow the voltage and time duration of a waveform to be measured precisely. They are useful when determining signal characteristics such as amplitude at specific points, the cycle time (duration) and frequency. There are three kinds of measurement rulers: the vertical Time Ruler, the horizontal Voltage Ruler, and the vertical Angle Ruler. Tap the Ruler Activator in the lower left corner of the grid and drag it across the screen to the desired position. A Time Ruler is generated. Tap the Angle Activator in the lower right corner of the grid and drag it across the screen to the desired position. An Angle Ruler is generated. 134 The two angle rulers are positioned to mark the start and end of a cycle. By default, the start and end angle values are 0 and 720, which can be configured in the Ruler Setting box. The Voltage Ruler can be generated in the similar way by tapping the Ruler Activator in the upper right corner and dragging it downwards. When Measurement Rulers are generated, a Ruler Table showing time and voltage values for the corresponding channels will be displayed.

Tap the left column of channel control button again to close the channel. The channel color changes to grey again. Channel Color The specific color of each input channel makes you identify the trace and read the corresponding waveform better. Table 9-3 Channel Color Table Input Channel A B C D Color Red Green Blue Yellow The amplitude, probe, low pass filtering and DLC channel settings can be configured in the Channel control dialog box. Amplitude Settings The amplitude settings allow you to set up the oscilloscope to capture signals with the specified range. If the input signal exceeds the selected range, an over-range indicator will be displayed. To solve this problem, you can select Auto to adjust the vertical scale automatically. 141 It only changes the vertical scale, while the horizontal scale is not changed. AC and DC voltage can be toggled to set up the input circuitry. Note Remember that the vertical scale is ALWAYS divided into 10 major divisions, and all scale settings reflect in these 10 divisions. The division set of 10 cannot be changed, so the 10 divisions cannot be added, or removed. There are two modes available to set the amplitude value. Mode 1: For example, selecting DC 5V sets the channel amplitude to 5 DC (seen at the right side of the channel control button), reflecting the entire vertical scale range is from -5V to +5V. As the vertical scale is divided into 10 segments, each segment is incremented by 1V. Figure 9-37 Channel Setting Dialog Box Screen 142 Figure 9-38 Sample Amplitude Setting Screen (DC 5V) Mode 2: Selecting the ## /div button can adjust value incremented by each division. For example, selecting AC 2.0V/div, sets the channel amplitude to 2.0V/div AC
(seen at the right side of the channel control button), reflecting each segment is incremented by 2V. As the vertical scale is divided into 10 segments, the entire vertical scale range is from -10V to +10V. Figure 9-39 Sample Amplitude Setting Screen (AC 2.0V/div) 143 Figure 9-40 Sample Amplitude Setting Screen (AC 2.0V/div) Probe Settings A probe is an accessory that connected to your oscilloscope and picks up signals to be measured. It can pick up different forms of signal, but generally delivers a voltage signal. This oscilloscope has built-in definitions of standard probes.

Trigger Mode Four trigger modes are available: None, Auto, Repeat and Single. You can select one mode according to your specific needs. Figure 9-55 Sample Trigger Mode Screen The table below offers brief description for each trigger mode. Table 9-4 Trigger Mode Table Trigger Mode Description None Auto In this trigger mode, the oscilloscope can continuously capture data, without waiting for a trigger event. In this trigger mode, the oscilloscope will wait for a trigger before capturing data. It can automatically update after a short period, even if the signal does not across the trigger point. Repeat In this trigger mode, the oscilloscope waits until a trigger event occurs. If there is no trigger event, nothing will be displayed on the screen. Single In this trigger mode, the oscilloscope stop capturing data once a trigger event occurs. Channel 154 You can select the applicable trigger channel in the dropdown list. The selected channel is the one that the oscilloscope monitors for the trigger condition. Figure 9-56 Sample Trigger Channel Screen Pulse Direction Two pulse direction settings are available: Rise and Fall.

Close the dialog box, and the corresponding measurement readings are displayed on the right-hand side of the screen. You can directly adjust the whole track or ruler track on the displayed screen, or delete the measurement directly by tapping the X button. 162 Figure 9-64 Sample Measurement Display Screen 9.1.6 Troubleshooting A. If the oscilloscope cannot communicate with the MaxiSys Display Tablet:
Check if the VCMI device is properly connected to the MaxiSys Display Tablet via the supplied USB cable or Wi-Fi network. If the communication between the VCMI device and the MaxiSys Display Tablet still fails, restart the MaxiSys Display Tablet and reconnect the VCMI device. B. If unwanted signals are displayed or some signals are displayed unclearly:
Please use the supplied test leads or probes to connect with the input channels. Check the test leads or probes for damage. Make sure the polarity of the test leads connections are correct. Make sure the signal and ground connections are clean and secure. Make sure the ground lead is providing a direct ground from the circuit to the input channel. Isolate the test leads from other components, leads, or systems that may induct unwanted noise into the signal being tested, for example, the electric motors, secondary ignition components, relays, alternators, etc. 163 9.1.7 Glossary AC/DC Control Each channel can be set to either AC coupling or DC coupling. With DC coupling, the voltage displayed onscreen is equal to the true voltage of the signal with respect to ground. With AC coupling, any DC component of the signal is filtered out, leaving only the variations in the signal for the AC component. Aliasing When the signal frequency gets higher than half the scopes maximum sampling rate and exceeds the limit, a distorted waveform appears. This distortion is called aliasing. Amplitude This term indicates the maximum voltage generated from the zero volts line of the oscilloscope. Analog Bandwidth All oscilloscopes have an upper limit to the range of frequencies at which they can measure accurately. The analog bandwidth of an oscilloscope is defined as the frequency at which a displayed sine wave has half the power of the input sine wave
(about 71% of the amplitude). Block Mode A sampling mode in which the computer prompts the oscilloscope to collect a block of data into its internal memory before stopping the oscilloscope and transferring the whole block into computer memory. This mode of operation is effective when the input signal being sampled is high frequency. Buffer Size/Cache Size This term indicates the size of the oscilloscopes buffer memory. The buffer memory is used by the oscilloscope to temporarily store data. This helps to compensate for the differences in data transfer rate from one device to another. Frequency This term describes the number of signal occurrences per second. Frequency is measured in Hz (hertz). 164 Peak to peak voltage This term indicates the difference in voltage between the minimum and maximum voltages occurring in the waveform. Time Base The time base controls the time interval across the scope display. Voltage Range The voltage range is the range between the maximum and minimum voltages that can be accurately captured by the oscilloscope. Sampling Rate This term is used to define the number of samples per second captured by the oscilloscope. The faster the sampling rate of the scope, the more frequently it measures the signal voltage, and so the more detailed will be the trace that appears on the scope screen. 165 9.2 Multimeter Operation A multimeter is a measuring instrument that is used to measure voltage, resistance, frequency, diode, duty cycle and pulse width as well as continuity test. The VCMI
(Vehicle Communication and Measurement Interface) working with MaxiSys Ultra can function as a multimeter to provide precise measurements. 9.2.1 Safety Information Follow the instructions below to reduce the risk of injury from electric shock and prevent equipment damage. Use the multimeter only as specified in this manual. Do not apply more than the rated voltage between terminals or between any terminal and earth ground. Do not input a value beyond the range when measuring. Remember that the limit value range of this multimeter is 200V. To prevent injury or death, do not use the multimeter if it appears to be damaged in any way, and stop use immediately if you are concerned with any abnormal operations. To prevent injury or death, never ground yourself when taking electrical measurements. Isolate yourself from ground by using dry rubber insulating mats to cover all exposed/grounded metal. Stand on rubber mats and wear dry clothing. Use the test leads or probes supplied with the product, or proper and applicable terminals. Inspect the test leads or probes for damage before use. When using probes, keep fingers behind the finger guards on the probes. Use the supplied replacement fuses or specified replacement parts. Always consider electrical and electronic equipment to be energized (live). Never assume any equipment is de-energized. When making electrical connections, connect the common test lead before connecting the live test lead; when disconnecting, disconnect the live test lead before disconnecting the common test lead. When measuring current, turn off circuit power before connecting the multimeter to the circuit. Remember to place the multimeter in series with the circuit. After current measurement is finished, turn off the power to the circuit before removing the test leads and before reconnecting any disconnected wires or devices. Do not add voltage to the input terminal when measuring resistance. 166 To avoid electric shock, turn off the power to the test component before testing it for connection. To prevent damage, always use and store your multimeter in appropriate environments. Do not use in wet or damp conditions, or around explosive gas or vapor. Do not tamper with or disassemble the multimeter, connectors or accessories. Internal damage will affect performance. Before carrying out maintenance and cleaning of the multimeter, make sure the unit is NOT connected to a power source, vehicle or computer.

NOTE The flashing lamps simply indicate that the communication signals are detected, rather than the correctness of the signals. Lower Buttons Protocol Button In the left lower corner of the screen, you can select the protocol you want to test. 228 Figure 9-11 Sample Protocol Button Screen The following protocols are included:
High Speed CAN - offers baud rates from 40 Kbit/s to 1 Mbit/sec, depending on cable length. This is the most popular standard for the physical layer, since it allows for simple cable connection between devices. High speed CAN networks are terminated with 120 ohm resistors on each end of the network. Low Speed CAN - offers baud rates from 40 Kbit/s to 125 Kbits/sec. This standard allows CAN bus communication to continue in case of a wiring failure on the CAN bus lines. In low speed CAN networks, each device has its own termination. Single CAN - offers baud rates up to 33.3 Kbit/s (up to 88.3 Kbit/s for high-speed mode) J1939 CAN - is used in the commercial vehicle area for communication throughout the vehicle, with the physical layer defined in ISO 11898. Under J1939/11 and J1939/15, the data rate is specified as 250 Kbit/s, with J1939/14 specifying 500 Kbit/s. J1850 (PWM) - SAE J1850 pulse-width modulation offers baud rates up to 41.6 Kbit/s, standard of the Ford Motor Company J1850 (VPW) - SAE J1850 variable pulse width offers baud rates up to 10.4 Kbit/s, standard of the General Motors J1708 (SAE) - the standard defines a double-wire 18-gauge cable that can run up to 130 feet (40 m) and operates at 9600 bit/s Waveform button 229 In the right lower corner of the screen, you can enter to the Waveform Mode by tapping the Waveform button. Figure 9-12 Sample Indicator Button Screen Test Procedure The test procedure is the same for all the protocols. To test the communication line:

Please refer to the Connection Diagram. 2. Turn the IG key to ON position. 3. Select the High Speed CAN protocol in the lower corner of the screen. 4. The OBDII connector pin numbers that the signals are being transmitted are indicated, and the indicator lamps flash consecutively. NOTE If the indicator lamps are not flashing, check the IG key ON status and the OBDII connector signal pin assignment, then make closer inspection on the circuit. Waveform Mode This mode allows you to view the test result in a waveform form with more details and set more configuration for specific needs. 230 The screen is displayed in the Indicator mode by default. Tap the Waveform button in the lower corner of the Indicator mode screen to switch to the Waveform Mode. The screen is shown as below. Figure 9-13 Sample Indicator Mode Screen Main View Section The main view section features as a coordinate grid with X-axis and Y-axis, representing the time duration and voltage level respectively. The voltage level can be configured in the Amplitude Settings while the time duration can be set in the Time Base Settings. Channel Selection In the main view section, a channel has two conditions: selected and unselected. Some operations depend on the selected condition of the channel, such as voltage rulers, waveform movements, and waveform zooming. To select and unselect the channel:
1. Tap the zero baseline marker or the Y-axis, which thickens to indicator the channel is selected. 2. Tap the zero baseline marker or the Y-axis again to exit the channel selection. Waveform Zooming 231 The zooming function allows you to change the size and position of a signal during or after capturing a waveform to examine it in greater details. It does not change the stored data, only the way it displays. The X-axis and Y-axis can be zoomed using your fingertips. The waveform can be zoomed during or after capturing the signal. Measurement Rulers In the coordinate grid, there are two kinds of measurement rulers, which allow the voltage and time duration of a waveform to be measured precisely. They are useful when determining signal characteristics such as amplitude at specific points, the cycle time (duration) and frequency. The vertical Time Ruler - Tap the Ruler Activator in the bottom left corner of the grid and drag it across the screen to the desired position. A Time Ruler is generated. The horizontal Voltage Ruler - The Voltage Ruler can be generated in the similar way by clicking the Ruler Activator in the top right corner and dragging it downwards. When Measurement Rulers are generated, a Ruler Table showing time and voltage values for the corresponding channels will be displayed. The Delta icon refers to the absolute difference between the values of the rulers, which can be locked by tapping the Lock icon. Tap the X button in the upper right corner of the ruler table to delete all rulers. Figure 9-14 Sample Measurement Rulers Screen Zero Baseline 232 The zero baseline is marked the 0 value in the Y-axis, showing the ground level of each channel waveform. After the channel is selected, the zero baseline can be adjusted by dragging the baseline marker up/down along the Y-axis, or dragging the waveform up/down or moving the screen up/down in the grid. NOTE Tapping the baseline marker makes the vertical scale line thinner. In this case, the waveform is unselected and cannot be dragged. Tap the baseline marker again to select.

Protocols include Controller Area Network (CAN), Local Interconnect Network (LIN) and others. CAN Bus A Controller Area Network (CAN bus) is a robust vehicle bus standard designed to allow microcontrollers and devices to communicate with each other in applications without a host computer. SAE International Initially established as the Society of Automotive Engineers, is a U.S.-based, globally active professional association and standards developing organization for engineering professionals in various industries. Principal emphasis is placed on transport industries such as automotive, aerospace, and commercial vehicles. SAE J1708 SAE J1708 is a standard used for serial communications between ECUs on a heavy duty vehicle and also between a computer and the vehicle. With respect to Open System Interconnection model (OSI), J1708 defines the physical layer. Common higher layer protocols that operate on top of J1708 are SAE J1587 and SAE J1922. The protocol is maintained by SAE International. 244 SAE J1939 Society of Automotive Engineers standard SAE J1939 is the vehicle bus recommended practice used for communication and diagnostics among vehicle components. It is used in the commercial vehicle area for communication throughout the vehicle, with the physical layer defined in ISO 11898. J1850 Defines a serial data protocol. There are two variants- 10.4 Kbit/s (single wire, VPW) and 41.6 Kbit/s (two wire, PWM). Mainly used by US manufacturers, also known as PCI
(Chrysler, 10.4 Kbit/s), Class 2 (GM, 10.4 Kbit/s), and SCP (Ford, 41.6 Kbit/s). OBD On-board diagnostics (OBD) to a vehicle's self-diagnostic and reporting capability. OBD systems give the vehicle owner or repair technician access to the status of the various vehicle subsystems. is an automotive term referring OBD-II diagnostic connector The OBD-II DLC (post-1996 vehicles) is usually located under the instrument panel on the driver side, though there are several exceptions.

Use a soft cloth and alcohol or a mild window cleaner to clean the touch screen of the tablet. Do not use any abrasive cleansers, detergent, or automotive chemicals to the tablet. Maintain the devices in dry conditions and keep them within normal operating temperatures. Dry your hands before using the tablet. The touch screen of the tablet may not work if the touch screen is moist, or if you tap the touch screen with wet hands. Do not store the devices in humid, dusty or dirty areas. Check the housing, wiring, and connectors for dirt and damage before and after each use. At the end of each work day, wipe the device housing, wiring, and connectors clean with a damp cloth. Do not attempt to disassemble your tablet or the VCMI unit. Do not drop or cause severe impact to the devices. Use only authorized battery chargers and accessories. Any malfunction or damage caused by the use of unauthorized battery charger and accessories will void the limited product warranty. Ensure that the battery charger does not come in contact with conductive objects. Do not use the tablet beside microwave ovens, cordless phones and some medical or scientific instruments to prevent signal interference. 21.2 Troubleshooting Checklist A. When the tablet does not work properly:
291 Make sure the tablet has been registered online. Make sure the system software and diagnostic application software are properly updated. Make sure the tablet is connected to the Internet. Check all cables, connections, and indicators to see if the signal is being received. B. When battery life is shorter than usual:
This may happen when you are in an area with low signal strength. Turn off your device if is not in use. C. When you cannot turn on the tablet:
Make sure the tablet is connected to a power source or the battery is charged. D. When you are unable to charge the tablet:
Your charger maybe out of order. Contact your nearest dealer. You may be attempting to use the device in an overly hot/cold temperature. Charge the device in a cooler or warmer area. Your device may have not been connected to the charger properly. Check the connector. NOTE If the problems persist, please contact Autels technical support personnel or your local selling agent. 21.3 About Battery Usage Your tablet is powered by a built-in Lithium-ion Polymer battery. This means that, unlike other forms of battery technology, you can recharge your battery while some charge remains without reducing your tablets autonomy due to the battery memory effect inherent in those technologies. DANGER The built-in Lithium-ion Polymer battery is factory replaceable only; incorrect replacement or tampering with the battery pack may cause an explosion. Do not use a damaged battery charger. Do not disassemble or open crush, bend or deform, puncture or shred. Do not modify or remanufacture, attempt to insert foreign objects into the battery, expose to fire, explosion or another hazard. 292 Use only the included charger and USB cables. Failure to use Autel-authorized charger and/or USB cables, may result in device malfunction or failure. Use of an unqualified battery or charger may present a risk of fire, explosion, leakage, or another hazard. Avoid dropping the tablet. If the tablet is dropped, especially on a hard surface, and the user suspects damage, take it to a service center for inspection. The closer you are to your networks wireless router, the longer your tablet usage time because less battery power is consumed for the connection. The battery recharging time varies depending on the remaining battery capacity. Battery life inevitably shortens over time. Since overcharging may shorten battery life, remove the tablet from its charger once it is fully charged. Unplug the charger, once charging is complete. Leaving the tablet in hot or cold places, especially inside a car in summer or winter, may reduce the capacity and life of the battery. Always keep the battery within normal temperatures. 21.4 Service Procedures This section introduces information for technical support, repair service, and application for replacement or optional parts. 21.4.1 Technical Support If you have any question or problem on the operation of the product, please contact us.

These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:
Reorient or relocate the receiving antenna. Increase the separation between the equipment and receiver. Consult the dealer or an experienced radio/TV technician for help. This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions:
(1) This device may not cause harmful interference, and
(2) this device must accept any interference received, including interference that may cause undesired operation. Changes or modifications not expressly approved by the party responsible for compliance could void the users authority to operate the equipment. SAR The radiated output power of this device is below the FCC radio frequency exposure limits. Nevertheless, the device should be used in such a manner that the potential for human contact is minimized during normal operation. The exposure standard for wireless devices employs a unit of measurement known as the Specific Absorption Rate, or SAR. The SAR limit set by the FCC is 1.6 W/Kg. Tests for SAR are conducted using standard operating positions accepted by the FCC with 296 the device transmitting at its highest certified power level in all tested frequency bands. Although the SAR is determined at the highest certified power level, the actual SAR level of the device while operating can be well below the maximum value. This is because the device is designed to operate at multiple power levels so as to use only the power required to reach the network. To avoid the possibility of exceeding the FCC radio frequency exposure limits, human proximity to antenna should be minimized. 297 23 Warranty 23.1 12-Month Limited Warranty Autel Intelligent Technology Corp., Ltd.
