Diagnostic Instructions

Perform the Diagnostic System Check - Vehicle prior to using this diagnostic procedure. Initial Inspection and Diagnostic Overview

Review Strategy Based Diagnosis for an overview of the diagnostic approach.

Diagnostic Procedure Instructions provide an overview of each diagnostic category.

Circuit/System Description

The body control module (BCM) receives a discrete input from the driver door ajar switch, the passenger door ajar switches, and the liftgate ajar switch. The door ajar switches are normally open when the doors are fully closed. When a door is opened, the door ajar switch contacts close providing a path to ground. The driver information center (DIC) located at the bottom of the instrument panel cluster (IPC), illuminates the appropriate door ajar message when one of the doors is open. The IPC receives a serial data message from the BCM indicating the door ajar status. If this message is displayed and the vehicle speed is greater than 8.1 km/h (5 mph), a chime will sound.

Circuit/System Testing

1. Ignition ON, open and close the driver and passenger doors. Check to see if the dome lamps are operating properly.

• If the dome lamps are not operating properly, refer to Symptoms - Lighting Systems.

2. If the dome lamps are operating properly, replace the IPC.
