Pinpoint Test AF: The DOOR AJAR Warning Is Inoperative

Refer to Wiring Diagram Set 60, Instrument Cluster for schematic and connector information. Diagrams By Number

Normal Operation

The door ajar switches are hardwired to the Driver Door Module (DDM). When any door is open and the ignition key is in the RUN position, the DDM sends the Instrument Cluster (IC) a message over the Standard Corporate Protocol (SCP) communication network to illuminate the door ajar warning indicator.

This pinpoint test is intended to diagnose the following:

- Interior lamp system
- DDM
- IC
