DTC DESCRIPTORS

DTC B3265 01
Hatch Release Output Circuit Short to Battery

DTC B3265 06
Hatch Release Output Circuit Short to Ground or Open




DIAGNOSTIC FAULT INFORMATION

CIRCUIT/SYSTEM DESCRIPTION
The body control module (BCM) provides voltage to the liftgate release relay control circuit thus energizing the LIFTGATE RELEASE Relay which provides voltage to the release actuator releasing the liftgate.

CONDITIONS FOR RUNNING THE DTC
Battery voltage must be between 9-16 volts.

CONDITIONS FOR SETTING THE DTC

B3265 01
This DTC will set when the BCM detects a short to battery in the liftgate release relay control circuit.

B3265 06
This DTC will set when the BCM detects an open or short to ground in the liftgate release relay control circuit.

ACTION TAKEN WHEN THE DTC SETS
- The BCM stores the DTC to memory.
- The rear compartment lid latch will malfunction.

CONDITIONS FOR CLEARING THE DTC
- This DTC will change from current to history when the fault is no longer present.
- A history DTC will clear after 100 consecutive ignition cycles if the condition for the malfunction is no longer present.
- The technician issues a scan tool CLEAR DTCs command.

CIRCUIT/SYSTEM VERIFICATION
Command the liftgate release with the scan tool. The liftgate door latch release actuator should release the liftgate.

CIRCUIT/SYSTEM TESTING
1. Ignition OFF, disconnect the LIFTGATE RELEASE relay.
2. Ignition OFF, test for less than 1.0 ohm of resistance between the relay coil ground circuit terminal and ground while pressing the liftgate release switch.
- If greater than the specified range, test for an open/high resistance.
3. Connect a test lamp between the liftgate release relay control terminal and the relay coil ground circuit terminal.
4. Command the Hatch Release ON and OFF by pressing and releasing the touchpad. The test lamp should turn ON and OFF when changing between the commanded states.
- If the test lamp is always ON, test the control circuit for a short to voltage. If the circuit tests normal, replace the BCM.
- If the test lamp is always OFF, test the control circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the BCM.
5. If all circuits test normal, test or replace the LIFTGATE RELEASE relay.

COMPONENT TESTING

Relay Test
1. Ignition OFF, disconnect the LIFTGATE RELEASE relay.
2. Test for 60-180 ohms of resistance between terminals 85 and 86.
- If the resistance is not within the specified range, replace the relay.
3. Test for infinite resistance between the following terminals:
- 30 and 86
- 30 and 87
- 30 and 85
- 85 and 87
- If not the specified value, replace the relay.

4. Install a 25-amp fused jumper wire between relay terminal 85 and 12 volts. Install a jumper wire between relay terminal 86 and ground. Test for less than 2 ohms of resistance between terminals 30 and 87.
- If greater than the specified range, replace the relay

REPAIR INSTRUCTIONS
Perform the Diagnostic Repair Verification after completing the diagnostic procedure. Verification Tests
- Relay Replacement (Attached to Wire Harness) Relay Replacement (Within an Electrical Center)
- Control Module References for BCM replacement, setup and programming. Programming and Relearning
