Power Door Lock System

The [1][2]Central Timer Module ([1][2]CTM) controls the door lock actuator assemblies to handle locking and unlocking with the key fob or interior switch. There is also a door lock inhibit feature that prevents power locking of the doors if the ignition is OFF and the key is in the ignition. Automatic or rolling locks are included as a DRB programmable feature. If the vehicle is moving approximately 5 mph and approximately degrees of throttle opening is seen by the PCM, (the PCM will send this info to the CTM via the CCD bus) indicating acceleration, the CTM will cycle the lock actuators.
