Pinpoint Test AQ: The DRIVER, PASSENGER, REAR LEFT, REAR RIGHT DOOR AJAR or LIFTGATE Warning Is Inoperative/Always On

Normal Operation

The Instrument Cluster (IC) receives the door ajar status for the LH front, RH front, LH rear and RH rear door ajar switch from the Smart Junction Box (SJB) over the Medium Speed Controller Area Network (MS-CAN) communication bus. When the IC receives a message from the SJB that one or more doors are open or ajar, the IC turns on the applicable door ajar warning.

NOTE: If DTC U0140 is set in the SJB, other symptoms may also be present such as high beam indicator, RH/LH turn indicators, instrument panel backlighting and Tire Pressure Monitoring System (TPMS).

This pinpoint test is intended to diagnose the following:

- Interior lighting concern
- IC
