Scheme 65

There are two contact breakers in the lock units in the side doors

1. contact breaker to indicate if the door is ajar (not fully closed)
2. contact breaker to indicate that the central locking motor is in the locked position.

The contact breaker which indicates if the door is ajar is directly connected to the central electronic module (CEM) from all doors.

The contact breaker for indicating the status of the central locking motor is connected to the relevant rear control module for the rear doors. The rear door control modules transmit the signal on to the relevant control module in the front doors which forward the signal to the central electronic module (CEM).

The signals are used to generate error messages and diagnostic trouble codes (DTCs) if a door is not properly closed when the vehicle is driven or if locking or unlocking of one or more doors has failed one or more times.

There is only one contact breaker in the lock unit in the tailgate/trunk lid. This indicates whether the tailgate/trunk lid is open or closed.
