DTC B2996 00

- Left Rear Door Ajar Circuit

DTC B3001 00

- Right Rear Door Ajar Circuit

Diagnostic Fault Information

Circuit/System Description

The body control module (BCM) monitors the rear door ajar circuits to indicate the status of the rear doors. When the respective door is opened, the

door ajar signal circuit is switched to ground by the door lock ajar indicator switch, the BCM detects the drop in voltage in the circuit and then

communicates this status to the instrument panel cluster (IPC) via a serial data message. The IPC, upon receipt of this serial data message, will

illuminate the appropriate ajar message in the driver information center (DIC) and when the transaxle is shifted out of PARK, the DIC will also

send a serial data message to the radio to activate the door ajar audible warning.

Conditions for Running the DTC

The system voltage is 9-18 volts.

Conditions for Setting the DTC

The BCM detects a short to ground in a rear door ajar circuit for longer than 10 minutes.

Action Taken When the DTC Sets

The appropriate door ajar indicator is continuously illuminated.

Conditions for Clearing the DTC

* The DTC will be current for as long as the fault is present.

* When the fault is no longer present, the DTC will be a history DTC.

* A history DTC will clear after 50 ignition cycles.
