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

Normal Operation

The door ajar indicator informs the driver if any of the doors, the luggage compartment lid or the hood is not completely closed. The door ajar information is sent from the Body Control Module (BCM) to the Instrument Panel Cluster (IPC) over the Medium Speed Controller Area Network (MS-CAN) communication bus.

If the door ajar status is missing or if the data is deemed invalid for less than 5 seconds, the door ajar warning indicator remains in the last indication mode (on or off) based on the last known good request received. If the door ajar status is missing for more than 5 seconds, the IPC (Instrument Panel Cluster) sets DTC U0140:00 in continuous memory and defaults the door ajar warning indicator off.

This pinpoint test is intended to diagnose the following:

- Interior lamps concern

- Hood ajar concern

- Decklid ajar concern

- Wiring, terminals or connectors

- BCM (Body Control Module)

- IPC (Instrument Panel Cluster)
