Door Lock Operation

The vehicle is equipped with power door locks. Each lock actuator is powered and controlled by the door module mounted in the individual door. The Rear Integration Module (RIM), while it has no actual inputs or outputs related to door locking, is the master logic controller for the lock system.

When a power door lock switch is pressed, the door module that detected it will report this status via the Serial Data Class 2 line to the RIM. The RIM will then determine if locking or unlocking is permitted and if it is, will then command the door modules to LOCK or UNLOCK the doors.

Personalization features, such as the automatic door lock operation modes and the delayed locking feature are also controlled by the RIM. The features are changed by using the Driver Information Center (DIC) or Tech 2 scan tool.
