Circuit/System Description
The body control module (BCM) provides voltage to the liftgate release relay control circuit thus energizing the L/GATE RELSE relay which provides voltage to the liftgate latch releasing the liftgate.
Conditions for Running the DTC
The system voltage is 9-16 volts.
Conditions for Setting the DTC
B3265 01
The BCM detects a short to battery in the liftgate release relay control circuit.
B3265 06
The BCM detects an open or short to ground in the liftgate release relay control circuit.
Action Taken When the DTC Sets
The liftgate latch will malfunction.
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. |
Diagnostic Aids
Before testing can be performed the liftgate must be opened. Refer to Opening the Liftgate Without Electrical Power for the appropriate procedure.

Circuit/System Verification
Command all the doors to UNLOCK by using the door lock switch, command the liftgate door latch to release by pressing the liftgate release switch. The liftgate door latch should release the liftgate.
Circuit/System Testing
- Ignition OFF, disconnect the L/GATE RELSE relay.
- Connect a test lamp between the control circuit terminal 86 and B+.
- Command the liftgate release ON and OFF by pressing and releasing the liftgate release switch. The test lamp should turn ON and OFF when changing between the commanded states .
- Connect a test lamp between the control circuit terminal 85 and ground.
- Command the liftgate release actuator ON and OFF by pressing and releasing the liftgate release switch. The test lamp should turn ON and OFF while changing between the commanded states.
- If all circuits test normal, test or replace the L/GATE RELSE relay.
| ⇒ | If the test lamp is always OFF, test the control circuit for an open/high resistance. |
| ⇒ | If the test lamp is always ON, test the control circuit for a short to ground. |
| ⇒ | 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. |
Component Testing
Relay Test
- Ignition OFF, disconnect the L/GATE RELSE relay.
- Test for 60-180 ohms between terminals 85 and 86.
- Test for infinite resistance between the following terminals:
- 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 between terminals 30 and 87.
| ⇒ | If not within the specified range, replace the relay. |
| • | 30 and 86 |
| • | 30 and 87 |
| • | 30 and 85 |
| • | 85 and 87 |
| ⇒ | If not the specified value, replace the relay. |
| ⇒ | If greater than the specified range, replace the relay. |
