DTC Descriptor
DTC B3265 00
- Trunk/Hatch/Liftglass Release Output Circuit
Diagnostic Fault Information
Circuit/System Description
The BCM applies battery positive voltage to the trunk release relay control circuit, which energizes the coil side of the trunk relay. The switch side
of the trunk 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.
