Trunk Release Output Circuit High


Object Number: 864154  Size: MF

Circuit Description

The decklid/lift gate release is controlled by the body control module (BCM) providing battery voltage to the release solenoid by circuit 382. The BCM limits the amount of time the solenoid can be activated to 750 ms to prevent damage to the solenoid. Reactivation may not be allowed for as much as 30 seconds.

When the BCM receives a request to activate the decklid/lift gate release solenoid, it switches circuit 382 to battery to provide battery to the solenoid. Ground is provided to the solenoid by circuit 550.

Conditions for Setting the DTC

    • Decklid/lift gate release not requested
    • Circuit 382 shorted to battery voltage
    • Condition exists for 30 seconds

Diagnostic Aids

    • Inspect the wiring harness for damage. Inspect for broken or chafed insulation.
    • If a fault is suspected to be intermittent, wiggling the harness wiring may help in locating the fault.
