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 BCM stores the DTC to memory.
* The lift 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 Int Trunk/Liftglass Sw. parameter while pressing and releasing the liftgate switch. The parameter should change between Active and Inactive.

Circuit/System Testing

1. Ignition OFF, disconnect the harness connector at the liftgate switch.
2. Test for less than 1.0 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, verify the scan tool Int Trunk/Liftglass Sw parameter is Inactive.

• If not the specified parameter, test the signal circuit terminal A for a short to ground. If the circuit tests normal, replace the BCM.

4. Install a 3A fused jumper wire between the signal circuit terminal A and the ground circuit terminal C. Verify the scan tool Int Trunk/Liftglass Sw. parameter is Active.

• If not the specified parameter, test the signal circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace the BCM.

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

Component Testing

Liftgate Switch

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

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

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

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

Repair Instructions
