Door Ajar Indicator System Components
The door ajar indicator system consists of the following components:

Driver Door Ajar And Passenger Door Ajar
The BCM receives a discrete input from the respective door ajar switch to indicate
the status of the door. The BCM then communicates this status to the IPC via class 2
message. The IPC, upon receipt of this class 2 message, will illuminate the
appropriate door ajar message in the DIC and also send a class 2 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 8.05 km/h (5 mph) |
