Tests AM: The Door Ajar Reconfigurable Telltale Indicator Is Never/Always On

PINPOINT TEST AM: THE DOOR AJAR RECONFIGURABLE TELLTALE INDICATOR IS NEVER/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 instrument cluster (IC) receives a message from the SJB that one or more doors are open or ajar, the instrument cluster (IC) turns on the door ajar reconfigurable telltale indicator. If the door ajar status message is missing for greater than 5 seconds, the instrument cluster (IC) sets DTC U0140 and defaults the door ajar reconfigurable telltale indicator on.

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
- SJB
- Instrument cluster (IC)
