Test E: The Luggage Compartment Lid Release Is Inoperative/Does Not Operate Correctly

PINPOINT TEST E: THE LUGGAGE COMPARTMENT LID RELEASE IS INOPERATIVE/DOES NOT OPERATE CORRECTLY

Normal Operation
The battery junction box (BJB) fuse 8 (20A) provides voltage for the power lock/unlock system and to the luggage compartment lid latch (on vehicles without power luggage compartment lid release). The voltage is supplied to the driver door module (DDM) through circuit 1213 (WH/LB). The luggage compartment lid release switch receives voltage from the central junction box (CJB) through circuit 1524 (DB). When the luggage compartment release switch is pressed, voltage is supplied through the switch to the DDM through circuit 26 (WH/VT).

For vehicles not equipped with a power luggage compartment lid, the DDM supplies voltage through circuit 605 (RD) to the luggage compartment release solenoid, releasing the luggage compartment lid. The luggage compartment lid release solenoid is grounded through circuit 57 (BK).

For vehicles equipped with a power luggage compartment lid, the DDM sends a ground signal to the liftgate/trunk module (LTM) on circuit 1237 (LG/RD) to open or close the luggage compartment lid.

The luggage compartment lid release switch is disabled when the perimeter alarm is armed. Once the perimeter alarm is disabled, the luggage compartment lid can be released from the release switch.

- DTC B1553 (Decklid Release Circuit Short To Battery) - is a continuous and on-demand DTC that sets when the DDM detects a short to voltage on the luggage compartment lid release switch input circuit 26 (WH/VT). The DTC is also set if the luggage compartment lid release switch is pressed for longer than 2 minutes.
- DTC B2718 (Liftgate/Decklid Ajar Output Short to Battery) - is a continuous and on-demand DTC that sets when the DDM detects a short to voltage on the luggage compartment lid release output circuit 605 (RD).
- DTC B2703 (Open/Close Switch Stuck Active) -is a continuous and on-demand DTC that sets when the LTM detects a short to ground on the open/close input signal circuit 1237 (LG/RD).

This pinpoint test is intended to diagnose the following:
- Fuse
- Wiring, terminals or connectors
- Luggage compartment lid release solenoid (part of the luggage compartment lid latch)
- Luggage compartment lid release switch
- LTM
- DDM
