1. Boot Release Malfunction

2. Trunk Release Exterior Switch Malfunction

Circuit/System Description

The body control module (BCM) applies battery positive voltage to the boot release relay control circuit, which energises the coil side of the rear compartment lid release relay. The switch side of the rear compartment lid release relay then closes, supplying battery positive voltage through the relay and the latch motor voltage control circuit to the rear compartment lid latch. The rear compartment lid latch then releases the rear compartment lid so that it may be manually raised to an open position.

Conditions for Running the DTC

Battery voltage must be between 9-16 V.

Conditions for Setting the DTC

The BCM detects a short to ground on the boot release relay control circuit.

Action Taken When the DTC Sets

The rear compartment latch will not operate.

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 trunk release with a scan tool. The rear compartment lid actuator should release the trunk lid.

Circuit/System Testing

  1. Ignition OFF, disconnect the X5 harness connector at the K9 Body Control Module.
  2. Test for greater than 50 Ω between the control circuit terminal 25 X5 and ground.
    3. ⇒ If less than the specified value, test the control circuit for a short to ground. If the circuit tests normal, replace the X50A Fuse Block - Underhood.
  3. If all circuits test normal, replace the K9 Body Control Module

Repair Instructions

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
