DTC Descriptor
DTC B3265 61
- Trunk Release Switch Stuck

Diagnostic Fault Information





Circuit/System Description

Pressing the liftgate release switch closes a contact providing a ground for the liftgate release switch signal circuit. The rear fuse block will detect the voltage drop and command voltage to be supplied to the liftgate latch assembly which releases the liftgate.

Conditions for Running the DTC

The system voltage is 9-16 volts.

Conditions for Setting the DTC

The rear fuse block detects a short to ground in the liftgate release switch signal circuit for greater than 60 seconds.

Action Taken When the DTC Sets

The liftgate latch will malfunction.

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.

Circuit/System Verification

Ignition ON, observe the scan tool Trunk Release Switch parameter while pressing and releasing the liftgate release switch. The parameter should change between Active and Inactive.

Circuit/System Testing

1. Ignition OFF, disconnect the harness connector at the liftgate release switch.
2. Ignition ON, verify the scan tool Trunk Release Switch parameter is Inactive.

• If not the specified value, test the signal circuit terminal 1 for a short to ground. If the circuit tests normal, replace the rear fuse block.

3. If all circuits test normal, test or replace the liftgate release switch.

Component Testing

1. Ignition OFF, disconnect the harness connector at the liftgate release switch.
2. Test for infinite resistance between the signal terminal 1 and the ground terminal 3 with the switch in the open position.

• If not the specified value, replace the liftgate release switch.

3. Test for less than 2 ohms between the signal terminal 1 and the ground terminal 3 with the switch in the closed position.

• If greater than the specified range, replace the liftgate release switch.

Repair Instructions

Perform the Diagnostic Repair Verification (Verification Tests) after completing the diagnostic procedure.
