Passenger Door Ajar Switch

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