There are two different capacitive sensors. The first sensor is used for unlock function. This sensor can distinguish an approach and a touch in SW, but there is only a LIN or UART signalization for unlock touch. The second sensor is used for lock function and is designed as a touch sensor. A SW differentiation between lock approach and lock touch is also possible, but just as the unlock sensor there is only a LIN or UART signalization for the lock touch. Keyless access is enabled by activating the sensors on the door handle in combination with the door handle-ECU, whereby the vehicle can be unlocked or locked. 1.1.2 Function NFC:

To enable communication with an NFC device, the door handle electronics CA + NFC has a highly integrated transceiver IC for contactless communication at 13,56MHz for automotive applications. This reader has a gateway function, the possibility to buffer required data and various diagnostic informations can be provided as well. The data is transferred to the NFC device according to ISO/IEC 14443-A and the data transmission to the vehicle is realized via LIN-Bus interface. ECP is implemented to communicate with Apple NFC devices. In LPCD mode the door handle electronics checks the magnetic field for amplitude or phase change. This LPCD polling takes place in adjustable interval lengths. 1.2 Environmental conditions

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.

-Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.

-Consult the dealer or an experienced radio/ TV technician for help. CAUTION:

Any changes or modifications not expressly approved by the grantee of this device could void the user's authority to operate the equipment 3.2 Canada, Innovation, Science and Economic Development Canada (ISED) Notices This device contains licence-exempt transmitter(s)/receiver(s) that comply with Innovation, Science and Economic Development Canadas licence-exempt RSS(s).
