Automatic Door Locks

The automatic door lock function provides for locking or unlocking the doors when shifting the transmission in and out of PARK.

When this feature is active, the RCDLR module receives Powertrain Control Module (PCM) shift select changes over the class 2 data line. When the ignition is in RUN, the driver door is closed, and the gear selector is shifted out of PARK, the RCDLR module will transmit a class 2 lock doors message to the DDM. The DDM will send this message on to the other door modules over the Simple Bus Interface (SBI) and the modules will lock their doors as programmed. If personalization is selected to do so, the RCDLR will also unlock the doors when the gear selector lever is put back in to PARK. For customized selections available and programming instructions, refer to: Personalization Description and Operation in Personalization
