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

Normal Operation 

The instrument cluster (IC) receives the door ajar status for the LH front door, RH front door, LH rear door, RH rear door and liftgate status 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 indicator. If the door ajar status message is missing for more than 5 seconds, the instrument cluster (IC) sets DTC U0140 in continuous memory and defaults the door ajar indicator on.

NOTE: If DTC U0140 is set in the instrument cluster (IC), other observable symptoms may also be present such as tire pressure monitoring system (TPMS) warning indicator, backlighting and door ajar indication.

Pinpoint Test AO: The Compass Is Inaccurate 

Normal Operation 

The compass sensor module (integrated into the auto-dimming interior mirror) communicates the vehicle direction to the instrument cluster (IC) through the compass communication data plus circuit VMC31 (YE/GN) and compass communication data minus circuit VMC30 (BU/GY). The magnetic fields generated by the earth's north and south poles are divided into zones that differ from each other with respect to how the magnetic fields appear. The magnetic north can change by up to 4 degrees between zones and become noticeable across multiple zones. The compass zone must be set to the correct zone for the compass to read accurately. Factors within the vehicle may affect the ability of the compass module to accurately read the magnetic north. Calibrating the compass allows the compass module to compensate for vehicle factors that influence the accuracy of the compass.
