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
- Ignition OFF, disconnect the X5 harness connector at
the K9 Body Control Module.
- Test for greater than 50 Ω between the control
circuit terminal 25 X5 and ground.
| ⇒ |
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. |
- If all circuits test normal, replace the K9 Body
Control Module

Diagnostic Repair Verification after completing the diagnostic
procedure.
