DTC Descriptor
DTC B3265 02
-
Trunk Lid Unlatch Output Circuit Short to Ground
Diagnostic Fault Information
Circuit/System Description
The body control module (BCM) applies battery positive voltage to the trunk relay control circuit, which energizes the coil side of the rear closure relay. The switch side of the rear closure relay then closes, supplying battery positive voltage through the relay and the relay controlled output circuit to the rear compartment lid latch. The rear compartment lid latch then releases the trunk lid so that it may be manually raised to an open position.
Conditions for Running the DTC
When the rear compartment lid latch release is actively being requested by the BCM.
Conditions for Setting the DTC
The BCM detects a short to ground in the compartment lid release relay control circuit.
Action Taken When the DTC Sets
The rear compartment lid latch will not release the deck lid.
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 rear compartment lid latch to UNLATCH with a scan tool. The rear compartment lid latch should UNLATCH and release the trunk lid.
Circuit/System Testing
1. Ignition OFF, disconnect the KR95B rear compartment lid unlatch relay.
2. Test for less than 10 ohms between the ground circuit terminal 1 and ground.
• If greater than the specified range, test the ground circuit for an open/high resistance.
3. Connect a test lamp between the control circuit terminal 3 and the ground circuit terminal 1.
4. Ignition ON, command the rear compartment lid 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 body control module.
• 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 body control module.
5. If all circuits test normal, test or replace the KR95B rear compartment lid unlatch relay.
Component Testing
Relay Test
1. Ignition OFF, disconnect the KR95B rear compartment lid unlatch relay.
2. Test for 60-200 ohms between terminals 1 and 3.
• If not within the specified range, replace the KR95B rear compartment lid unlatch relay.
3. Test for infinite resistance between the following terminals:
* 4 and 3
* 4 and 5
* 4 and 1
* 5 and 1
• If less than the specified value, replace the KR95B rear compartment lid unlatch relay.
4. Install a 3 A fused jumper wire between the relay terminal 3 and 12 V. Install a jumper wire between relay terminal 1 and ground. Test for less than 2 ohms between terminals 4 and 5.
• If greater than specified range, replace the KR95B rear compartment lid unlatch relay.
