### Door Ajar Indicator System Components

The door ajar indicator system consists of the following components:

• | The rear fuse block

• | The driver information center

• | The driver door lock

• | The passenger door lock

• | The left rear door lock

• | The right rear door lock

• | The liftgate latch assembly

### Driver and Passenger Door Ajar Operation

The rear fuse block receives a discrete input from the respective jamb switch to indicate the status of the door. The rear fuse block then communicates this status to the driver information center and also send a serial data message to the radio to activate the door ajar audible warning when the following conditions are met:

• | The transmission is removed from PARK.

• | The vehicle speed is greater then 8 km/h (5 mph).

### Liftgate Ajar Operation

The instrument panel cluster illuminates the door ajar icon when the rear fuse block detects that the liftgate is ajar or open. The IPC receives a serial data message from the rear fuse block requesting illumination. If the vehicle is in the forward or reverse gear position, the rear fuse block activates an audible warning.
