Door Ajar System
DOOR AJAR SYSTEMThe door ajar state is used as an input for various control modules on the vehicle. The DRB III will display the state of the door ajar switches in Inputs/Outputs. It's important to note, that when a door is closed, the switch state of the DRB III will show OPEN, and when the door is open, the switch state will show CLOSED. During diagnosis, if a door is closed and the DRB III displays the switch state as CLOSED, it indicates a shorted door ajar circuit. If the door is open and the DRB III displays the switch state as OPEN, it indicates an open door ajar circuit.
