1. Liftgate Release Switch Malfunction 2. Liftgate Release Malfunction

### 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 9-16 volts.

### Conditions for Setting the DTC

The BCM detects short to voltage in the liftgate latch relay coil control ground 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 the liftgate latch to release by pressing the exterior liftgate control 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 control circuit terminal 86 and B+.
3. Command the liftgate latch assembly by pressing and releasing the exterior liftgate control 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 between terminals 85 and 86.

⇒ | If 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 the specified range, replace the L/GATE relay.

4. Install a 3A fused jumper wire between the relay terminal 85 and 12V. Install a jumper wire between relay terminal 86 and ground. Test for less than 2 ohms between terminals 30 and 87.

⇒ | If greater than the specified range, replace the L/GATE relay.

### Repair Instructions

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
