Driver's Door Lock
The lock/unlock signals from the driver's door lock cylinder are input to the driver's door module from the two microswitches on the lock cylinder. The driver's door switchblock module carries out the locking function of the driver's door.
The windows and sunroof can be closed or opened by holding the key in the lock/unlock position (convenience closing/opening feature).
The signal to lock the remaining doors and fuel filler flap is passed over the P-Bus to the GM III and passenger's door module. The locking of the passenger's door is carried out by the passengers door module. The rear doors, luggage compartment and fuel flap locking are carried out directly by the GM III. All four doors will be pulled into the double lock position when locking from the driver's door.
The control of the actuators in the front doors is through final stages in the door modules. The rear doors, trunk and fuel filler flap actuators are controlled by internal relays in the GM III. When locked, the GM III will not carry out any opening commands from the central locking button or luggage compartment interior release button.
