DTC DESCRIPTOR

DTC B3265
Trunk/Hatch/Liftglass 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
This DTC will set when the BCM detects a fault in the Rear Closure Handle Switch Open Signal circuit.

ACTION TAKEN WHEN THE DTC SETS
- The BCM stores the DTC to memory.
- The lift switch will be inoperative.

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
Ignition ON, observe the Ext Trunk/Liftglass Rel Sw parameter while pressing the Liftgate Switch. The reading should change between Active and Inactive.

CIRCUIT/SYSTEM TESTING
1. Ignition OFF, disconnect the harness connector at the Liftgate Switch.
2. Ignition ON, verify the scan tool Ext Trunk/Liftglass Rel Sw is Inactive.
- If not the specified value, test the signal circuit terminal A for a short to ground. If the circuit tests normal, replace the BCM.
3. Install a 3-A fused jumper wire between the signal circuit terminal A and ground. Verify the scan tool Ext Trunk/Liftglass Rel Sw is Active.
- If not the specified value, test the signal circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace the BCM.
4. If all circuits test normal, test or replace the Liftgate Switch

REPAIR INSTRUCTIONS
Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
1. Liftgate Outside Handle Replacement
2. Control Module References for BCM replacement, setup, and programming Verification Tests Programming and Relearning
