CENTRAL LOCKING - ZVM/ZKE IV

COMPARATIVE OVERVIEW







The locking and unlocking of the lock actuators is controlled from three relays in the control module. The door lock actuator "Pin Contacts" and lock micro-switches provide the inputs to the control module for locking/double locking and unlocking of the doors, trunk, fuel filler flap (and glove box on the E36iC only).

The relays in the module provide both power and ground depending on the direction of actuator movement (lock/unlock).
