(Body Control Module) HFM C1A model HFMC1A01. 1.2 Short Description of the complete system including HFM The HFMC1A01 is a radio frequency transmitter-receiver used in vehicle access systems. The vehicle access system includes:
Key fob, which is a remote device It includes a 315 MHz or 433.92 MHz transmitter, a 125 kHz LF receiver and a 125 kHz transponder LF Antennae Kazashi includes a coil antenna for 125 kHz transponder communication Hand Free Module (HFM):
It includes a 125 kHz LF long range and transponder transmitters and a 433.92 MHz receiver. The HFM drives 6 external dedicated antennae for the 125 kHz transmission. Two are located in the doors trims, one in the Bumper, two within the vehicle cockpit and one in the trunck. It includes also an integrated RF receiver for 433.92 MHz. The receiver is designed in direct placement. The system interacts with other modules such as:
Push Engine Start Body Control Module ESCL (Electronic Steering Lock Control) USM The main functions performed by the system are:
RKE functions (key less features) Hand Free functions for vehicle access and engine start LF antennae management Immobilizer Author:

1. The first way is to use the remote key functionality (RKE) by pressing one of the Lock or Unlock buttons on the ID Key. Data frames are then transmitted at 315 MHz or 433.92 MHz from the key fob ID of the car. The HFM processes the frames received and when the security code is correct, the doors are locked or unlocked automatically. Car access functions by remote control are allowed using any key fob type 2. The second way is to use the free hand mode Unlocking the vehicle:
If the car is locked, when the door request switch located in the door is pressed by car user which has a car key fob, the HFM transmits data frames at 125 kHz. When the key fob receives the data and recognizes the content of the inquiry, it transmits the code to the car at 433.92 MHz or 315 MHz (depending of key fob frequency type). The HFM processes the frames received and when the code is correct, the doors are automatically unlocked. Locking the vehicle:
If the car is unlocked, when the door request switch located in the door is pressed by car user which has a car key fob, the HFM transmits data frames at 125 kHz. When the key fob receives the data and recognizes the content of the inquiry, it transmits the code to the car at 433.92 MHz or 315 MHz (depending of key fob frequency type). The HFM processes the frames received and when the code is correct, the doors are automatically locked. Car access functions by hand free are allowed using any key fob type. Remarks:
The operating free hand mode range of the product model named HFMC1A01 is less than 15 meters. The maximum operational distance using the hand free mode of this product is: 3 meters Author:

2.0 HFMC1A01 User_Manual_Model_HFMC1A01_v2.0. docx 3 Engine Start There are two ways to start the Engine:
1. When the Hand free functions are disabled First User has to hold the key fob in front of Immobilizer antenna for at least than 30s after one of the following action: press of the START button on the dashboard, open or close a door or press vehicle brake pedal. Each key fob has a transponder. When the key fob is hold in front of Immobilizer antenna, the HFM sends a transponder recognition order to the key fob throw the Immobilizer antenna. The HFM performs a transponder authentication using 125 kHz transceiver. The key fob sends the authentication result to the HFM. Then the HFM sends on the CAN bus a message to the central unit and engine control unit to allow or not the START of the engine. The engine starts function is allowed using any key fob type. 2. When the Hand free functions are enabled The user does not need to hold the key fob in front of the Immobilizer antenna. The key fob should only be inside the vehicle. When the START button is pushed, the HFM sends a recognize message at 125 kHz link via internal LF antennas. Receiving this message, the key fob sends an authentication message at 433.92 MHz or 315 MHz (depending of the key fob frequency type) to the HFM. Then the HFM sends on the CAN bus a message to the central unit and engine control unit to allow or not the START of the engine. The engine start function is allowed using any key fob type. Author:
