DTC Descriptor

DTC B3265 00
- Hatch Release Output Circuit

Diagnostic Fault Information






Circuit/System Description

The body control module (BCM) provides voltage to the liftgate release relay control circuit thus energizing the L/GATE relay which provides voltage to the liftgate latch assembly releasing the liftgate.

Conditions for Running the DTC

The system voltage is 9-18 volts.

Conditions for Setting the DTC

The BCM detects a fault in the liftgate latch relay coil control circuit.

Action Taken When the DTC Sets

* The BCM stores the DTC to memory.
* 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

Important: 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 the liftgate latch to release by pressing the exterior liftgate switch. The liftgate latch assembly should release the liftgate.

Circuit/System Testing

1. Ignition OFF, disconnect the L/GATE relay.
2. Connect a test lamp between the liftgate relay control circuit terminal 86 and B+.
3. Command the liftgate latch assembly by pressing and depressing the exterior liftgate switch. The test lamp should turn ON and OFF when changing between the commanded states.

^ If the test lamp is always OFF, test the control circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace the BCM.
^ If the test lamp is always ON, test the liftgate relay high circuit for a short to ground. If the circuit tests normal, replace the BCM.

4. If all circuits test normal, test or replace the L/GATE relay.

Component Testing

1. Ignition OFF, disconnect the L/GATE relay.
2. Test for 60-200 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 less than infinite resistance, replace the L/GATE relay.

4. Install a 3-amp fused jumper wire between applicable relay terminal 85 and 12 volts. Install a jumper wire between relay terminal 86 and ground. Measure for less than 2 ohms of resistance between terminals 30 and 87.

^ If greater than 2 ohms, replace the L/GATE 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)
