Communication of transmitter key with vehicle, function - GF80.61-P-3013SM

MODEL 220, 215 as of 1.10.02 

Shown on model 220 

Reception ranges 

The inductive antennas generate fields to cover various reception ranges around the vehicle. The transmitter key can determine its position in relation to the vehicle from the overlap of several fields. The range is approx. 1.5 m

Function prerequisites: 

The keyless go control module (N69/5) causes the transmitter key (A8/1) to send its authorization code via radio and inductive antennas if

• a hand is inserted into a door handle (capacitve sensor)

  the capacitive sensors are only active for 72 hours after the last locking operation and when play protection is not active

• a door handle is pulled,
• the lock button on one of the door handles is pressed,
• the trunk lid release switch (S15/1) is pressed to open the trunk lid,
• the trunk lid keyless go button (S62/21) is pressed,
• the keyless go start/stop button (S2/3) is pressed.

Function sequence 

The vehicle wakes up the transmitter key.

The transmitter key determines its position in relation to the vehicle and transmits this information to the rear window antenna amplifier module (A2/12) with the authorization code.

The rear window antenna amplifier module (A2/12) converts the radio signal into a data signal The overhead control panel control module (N70) receives this data signal via a data line. The code included in the signal for authorization is transmitted to the EIS control module as CAN message.

The EIS control module (N73) checks the code and, if the code was correct, sends the corresponding command for lock/unlock or for engine start via the CAN data bus.
