DTC DESCRIPTOR

DTC B3265
Trunk/Hatch/Liftglass 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
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 Liftgate Latch Relay Supply Voltage circuit or 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
- 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
Command the Liftgate Release with the scan tool. The Liftgate Latch Assembly should release the liftgate.

CIRCUIT/SYSTEM TESTING
1. Ignition OFF, disconnect the L/GATE relay.
2. Ignition OFF, test for less than 1.0 ohm of resistance between the relay coil ground circuit terminal and ground while pressing the Exterior Liftgate Switch.
- If greater than the specified range, test for an open/high resistance. If the circuit tests normal, replace the BCM.
3. Connect a test lamp between the Liftgate Release Relay Control terminal and the relay coil ground circuit terminal.
4. Command the Liftgate Release ON and OFF with a scan tool. The test lamp should turn ON and OFF when changing between the commanded states.
- 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.
5. If all circuits test normal, test or replace the L/GATE relay.

COMPONENT TESTING

RELAY TEST
1. Ignition OFF, disconnect the L/GATE relay.
2. Test for 60-180 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 not the specified value, replace the relay.
4. 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 of resistance between terminals 30 and 87.
- If greater than the specified range, replace the relay.
