Door Ajar System

The door ajar and liftgate 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 liftgate are in. The DRBIII(R) will display the state of the door ajar and the liftgate ajar switches in Inputs/Outputs. It's important to note, that when any door, or the liftgate is closed, the switch state on the DRBIII(R) will show OPEN. When any door, or the liftgate is open the switch state on the DRBIII(R) will show CLOSED. During diagnosis, if a door or the liftgate is closed and the DRBIII(R) displays the switch state as CLOSED, it indicates a shorted ajar circuit. If the door or the liftgate is open and the DRBIII(R) displays the switch state as OPEN, it indicates an open ajar circuit.
