Door/Trunk Ajar Indicator/Lamp: Description and Operation
DOOR AJAR SYSTEM
The door ajar state is used as an input for various control modules on the vehicle. The DRB III (R) 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 on the DRB III (R) 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 (R) displays the switch state as CLOSED, it indicates a shorted door ajar circuit. If the door is open
and the DRB III (R) displays the switch state as OPEN, it indicates an open door ajar circuit.
