Door Ajar System

WARNING: This page is about a different car, the 2005 Dodge Stratus and 2005 Chrysler Sebring. However, it is still accessible from the selected car via links, so may be relevant.

The door ajar and decklid ajar states are used as inputs for the Body Control Module (BCM). The BCM uses these inputs to determine exactly what position the doors and decklid are in. The DRBIII® will display the state of the door ajar and the decklid ajar switches in Inputs/Outputs. It's important to note, that when any door, or the decklid is closed, the switch state on the DRBIII® will show OPEN. When any door, or the decklid is open the switch state on the DRBIII® will show CLOSED. During diagnosis, if a door or the decklid is closed and the DRBIII® displays the switch state as CLOSED, it indicates a shorted ajar circuit. If the door or the decklid is open and the DRBIII® displays the switch state as OPEN, it indicates an open ajar circuit.
