Right Rear Door Ajar

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