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)
