Pinpoint Test S: The Door Ajar Warning Indicator Is Never/Always On

Normal Operation

The door ajar warning indicator informs the driver that one or more doors, the liftgate or the liftglass is open while the ignition key is in the RUN position. When a door, liftgate, or liftglass is ajar, the Smart Junction Box (SJB) sends a message to the Instrument Cluster (IC) over the Medium Speed Controller Area Network (MS-CAN) to illuminate the door ajar warning indicator.

This pinpoint test is intended to diagnose the following:

- SJB
- IC
