Door/Trunk Ajar Indicator/Lamp: Description and Operation
Liftgate Ajar Indicator Lamp
CIRCUIT OPERATION
The liftgate ajar warning lamp is used to alert the operator that a liftgate is ajar. A chime tone is used along with the lamp for an audible warning.
Circuit G78 connects from the Body Control Module (BCM) to the liftgate ajar switch. The switch is normally OPEN with the liftgate closed.
When the liftgate is opened the switch CLOSES completing a path to ground on circuit Z1. This circuit terminates at the liftgate ground.
When the BCM sees that the liftgate is ajar it sends a message across the CCD Bus to the instrument cluster for lamp illumination.
