Driver Door Ajar Switch

The DDM receives a discrete input from the driver door ajar switch. The IPC and IRC receive the status of the driver door from the DDM via GMLAN serial data. When the driver door is open/ajar and the vehicle is in any gear other than PARK, the driver information center (DIC) will display DRIVER DOOR AJAR. If the door is still ajar and the vehicles speed is greater than 4.8 km/h (3 mph) the DDM will send GMLAN serial data message to the IRC requesting 5 chimes to sound.
