Door Ajar System

The door ajar, liftgate ajar, and the liftgate flip-up ajar states are used as inputs for various control modules on the vehicle. The DRBIII® will display the state of the door ajar, liftgate ajar, and liftgate flip-up ajar switches in Inputs/Outputs. It's important to note, that when a door, liftgate, or liftgate flip-up is closed, the switch state on the DRBIII® will show OPEN, and when the door, liftgate, or liftgate flip-up is open, the switch state will show CLOSED. During diagnosis, if a door, liftgate, or liftgate flip-up is closed and the DRBIII® displays the switch state as CLOSED, it indicates a shorted ajar circuit. If the door, liftgate, or liftgate flip-up is open and the DRBIII® displays the switch state as OPEN, it indicates an open ajar circuit.
