Body Rear End Schematics

Circuit Description

The rear compartment lid release solenoid is controlled by the body control module (BCM). The BCM supplies battery positive voltage to the rear compartment lid release solenoid when the keyfob trunk release button is pressed. When the rear compartment lid release control circuit is shorted to battery positive voltage for 30 seconds, DTC B3268 is set.

Conditions for Running the DTC

Voltage supplied to the body control module is in the normal operating range (approximately 9-16 volts).

Conditions for Setting the DTC

The rear compartment lid control circuit is shorted to battery positive voltage for 30 seconds.

Action Taken When the DTC Sets
    • The rear compartment lid release solenoid output is constantly on.
    • The BCM stores DTC B3268 in memory.

Conditions for Clearing the DTC
    • A current DTC B3268 will clear when the malfunction is longer present.
    • All BCM history codes clear after 100 ignition cycles (from OFF to ON) with no current codes active during the 100 ignition cycles.

Diagnostic Aids
    • If the rear compartment lid release control circuit is shorted to battery positive voltage, the rear compartment lid will not latch closed.
    • If the DTC is a history DTC, the problem may be intermittent. Perform the above tests while wiggling the wiring and connectors. This may cause the malfunction to appear.

Test Description

The number(s) below refer to the step number(s) on the diagnostic table.

  1. Listen for an audible click when the rear compartment lid release solenoid operates. Command both the ON and OFF states. Repeat the commands as necessary.

    2.

  2. Verifies that the body control module is providing voltage to the rear compartment lid release solenoid.

    3.

  3. Tests for an open in the ground circuit to the rear compartment lid release solenoid.

    4.

  4. Tests if voltage is constantly being applied to the rear compartment lid release solenoid.
