Driver Door Ajar

The driver door module (DDM) receives a discrete input from the driver door ajar switch. The integrated radio chassis (IRC) receives the status of the driver door from the DDM via class 2 serial data message. When the driver door is open and the vehicle is out of the PARK gear, the message is displayed on the driver information center (DIC). Also, if the vehicle speed is greater than 4.8 km/h (3 mph), the DIC displays the message and sends a class 2 serial data message requesting 5 chimes to sound. The door ajar indicator system only function is to alert the vehicle operator when a vehicle door has inadvertently been left ajar or open. Failure of the door ajar indicator system do not affect door locks or any other vehicle system.
