DTC B3265

Diagnostic Instructions

•	Perform the Diagnostic System Check - Vehicle prior to using this diagnostic procedure.

•	Review Strategy Based Diagnosis for an overview of the diagnostic approach.

•	Diagnostic Procedure Instructions provides an overview of each diagnostic category.

DTC Descriptors

DTC B3265 01: Boot Lid Uncatch Output Circuit Short to Battery

DTC B3265 02: Boot Lid Unlatch Output Circuit Short to Ground

DTC B3265 04: Boot Lid Uncatch Output Circuit Open

Diagnostic Fault Information

Circuit	Short to Ground	Open/High Resistance	Short to Voltage	Signal Performance
Control	B3265 02	B3265 04	B3265 01	--
Ground	--	B3265 04	--	--

The body control module (BCM) applies battery positive voltage to the lift glass/trunk motor release control circuit, which energizes the coil side of the liftgate release relay. The switch side of the liftgate release relay then closes, supplying battery positive voltage through the relay and the relay controlled output circuit to the liftgate latch. The liftgate latch then releases the liftgate so that it may be manually opened.

Conditions for Running the DTC

When the liftgate release relay is actively being requested by the BCM.

Conditions for Setting the DTC

B3265 01

The BCM detects a short to voltage on the liftgate release relay control circuit.

B3265 02

The BCM detects a short to ground on the liftgate release relay control circuit.

B3265 04

The BCM detects an open/high resistance on the liftgate release relay control circuit or an open/high resistance on the relay ground circuit.

Action Taken When the DTC Sets

The tailgate latch will malfunction.

Conditions for Clearing the DTC

•	This 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, command the M30 liftgate latch to UNLATCH with a scan tool. The M30 liftgate latch should release the liftgate.

Circuit/System Testing

Ignition OFF, disconnect the KR95A liftgate release relay.
Test for less than 10 Ω between the ground circuit terminal 85 and ground.

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

Connect a test lamp between the control circuit terminal 86 and the ground circuit terminal 85.
Ignition ON, command the M30 liftgate latch to UNLATCH with a scan tool, the test lamp should turn ON while commanding the UNLATCH state.

⇒	If the test lamp is always ON, test the control circuit for a short to voltage. If the circuit tests normal, replace the K9 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 K9 BCM.

If all circuits test normal, test or replace the KR95A liftgate release relay.

Component Testing

Relay Test

Ignition OFF, disconnect the KR95A liftgate release relay.
Test for 60-180 Ω between terminals 85 and 86.

⇒	If not within the specified range, replace the KR95A liftgate release relay.

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 KR95A liftgate release relay.

Install a 2 A fused jumper wire between relay terminal 85 and 12 V. Install a jumper wire between relay terminal 86 and ground. Test for less than 2 Ω between terminals 30 and 87.

⇒	If greater than the specified range, replace the KR95A liftgate release relay.

Repair Instructions

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
