B3267
Circuit Description
The rear compartment lid release circuit is completed by the BCM when it receives a trunk release request from the RCDLR trunk release button and the vehicle is in the PARK position. The BCM grounds circuit 253, energizing the rear compartment lid release relay.
Conditions for Setting the DTC
The BCM detects a short to ground or an open in circuit 253.
Action Taken When the DTC Sets
The BCM stores DTC B3267 in memory.
Conditions for Clearing the DTC
The BCM detects a short to ground in circuit 253.
A history DTC will clear after 100 consecutive ignition cycles if the condition for the malfunction is no longer present.
Using a scan tool.
Diagnostic Aids
The following conditions may cause an intermittent malfunction to occur:
An intermittent open or short to ground in circuit 253.
Poor connections at the BCM, or the rear compartment lid release relay terminals.
The rear compartment lid release relay coil is open.
The BCM is open or shorted to ground internally.
An intermittent open in circuit 1540.
If the DTC is a history DTC, the problem may be intermittent. Try performing the tests shown while moving wiring and connectors, this can often cause the malfunction to reappear.
DTC P1626 will set in the Powertrain Control Module (PCM) when the ignition switch is on with the Body Control module (BCM) disconnected. When BCM diagnostics and repairs are completed, refer to Engine Controls for additional information on PCM related DTCs.
Test Description
The number(s) below refer to the step number(s) on the diagnostic table.
2. This step checks for voltage in circuit 253.
3. The step determines whether the malfunction is intermittent or the BCM is faulty.
4. This step checks for a short to ground in circuit 253.
5. This step determines whether the short to ground is in circuit 253 or the rear compartment lid release relay is faulty.
6. This step checks for an open in circuit 253.
8. This step determines whether the circuit 1540 is open or the rear compartment lid release relay is faulty.
