Function sequence for door handle control point
The capacitive sensor in the door handle recognizes when the corresponding door handle is pulled slightly and transmits a signal to wake up the Keyless Go control unit and the Keyless Go system (KG)
The Keyless Go control unit transmits a signal via the Keyless Go cockpit antenna and Keyless Go interior compartment antenna to mute all transmitter keys in the interior compartment for a certain period of time.

Then a Keyless Go transmitter key should be recognized in the outer range, otherwise locking is not performed.
The access authorization from the Keyless Go transmitter key are received by the roof antenna module and are relayed to the Keyless Go control unit The Keyless Go control unit transmits this message to EIS control unit via the CAN-B bus

The EIS control unit checks the access authorization, after positive check it transmits the "Locking" command via the CAN-B bus. The "Locking" command is transmitted to the left and right front door control unit as well as to the rear SAM control unit. They then lock the door locks, the tank flap and the rear-end door electrically.

Errors occurring when locking are indicated by the instrument cluster (A1).
