Transmitter key set to "selective" unlocking
When the "Unlock Vehicle" button is pressed once the transmitter key sends a radio and infrared signal to the relevant receivers in the vehicle, These receive the signal and transmit its content via CAN to the EIS[EZS] control module (N73).

The EIS[EZS] control module (N73) checks the access authorization. If the access authorization is valid1 the EIS[EZS] control module (N73) sends the command for selective unlocking via CAN to the door control modules and the rear SAM control module with fuse and relay module (N10/2). These then unlock the door locks and the fuel filler flap, according to the setting for selective unlocking.

If a further unlock command is received, global unlocking takes place via the same CAN route.

Transmitter key set to "global" unlocking
When the "Unlock vehicle" button is pressed once the transmitter key sends a radio and infrared signal to the relevant receivers in the vehicle. If access authorization is issued, the EIS[EZS] control module (N73) sends the command for global unlocking via CAN to the door control modules and the rear SAM control module with fuse and relay module (N10/2). These then unlock the door locks, the fuel filler flap and the trunk lid.

Global and selective unlocking with the transmitter key enables the interior switches.


NOTE: The factory setting for selective unlocking opens: Driver's door and fuel filler flap.
