Door Ajar Indicator System Components
The door ajar indicator system consists of the following components:
| • | The driver door module (DDM) |
| • | The instrument panel cluster (IPC) |
| • | The driver information center (DIC) |
| • | The driver door latch assembly |
| • | The passenger door latch assembly |
| • | The left sliding door jamb switch |
| • | The right sliding door jamb switch |
| • | The liftgate ajar switch |
Driver and Passenger Door Ajar Operation
The body control module (BCM) receives a discrete input from the respective jamb switch to indicate the status of the door. The BCM then communicates this status to the instrument panel cluster (IPC) via a class 2 message. The IPC, upon receipt
of this class 2 message, will illuminate the appropriate ajar message in the driver information center (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 transaxle is removed from PARK |
| • | The vehicle speed is greater then 8.05 km/h (5 mph) |
