DTC Descriptor
DTC B3265 00
- Hatch Release Output Circuit

Diagnostic Fault Information





Circuit/System Description

Pressing the liftgate switch closes a contact providing a ground for the rear closure handle switch open signal circuit. The body control module (BCM) will detect the voltage drop and command voltage to be supplied to the liftgate latch relay supply voltage circuit, thus energizing the liftgate relay which provides voltage to the liftgate latch releasing the liftgate.

Conditions for Running the DTC

Battery voltage must be between 9-16 volts.

Conditions for Setting the DTC

The liftgate release switch signal circuit is active for longer than 10 minutes.

Action Taken When the DTC Sets

The liftgate release switch will be inoperative.

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 Solenoid Command parameter while pressing and releasing the liftgate release switch. The parameter should change between On and Off.

Circuit/System Testing

1. Ignition OFF, disconnect the harness connector at the liftgate release switch.
2. Test for less than 1 ohm between the ground circuit terminal C and ground.

• If greater than the specified range, test the ground circuit for an open/high resistance.

3. Ignition ON, test for greater than 9 volts between the signal circuit terminal A and ground.

• If less than the specified range, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the BCM.

4. Install a 3A fused jumper wire between the signal circuit terminal A and ground. Verify the scan tool Trunk Release Solenoid parameter is On.

• If not the specified value, test the signal circuit for a short to voltage. If the circuit tests normal, replace the BCM.

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

Repair Instructions

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