Door Ajar System

THE DOOR AJAR SYSTEM
Inputs are used by several of the control modules on this vehicle. The rear doors and liftgate Switches are hard wired to the body control module while the driver and passenger Switches are wired to their respected door modules. The DRB III input/outputs will display the state of the switch not the respective door state. In other words if the door is closed the DRB should show "Open" and when the door is open the DRB should show "closed". If the ajar state is "Closed" when the door is closed this would indicate a shorted circuit. If the ajar state is "Open" when the door is open this would indicate an "Open" circuit.
