Door Ajar Indicator System Components
The door ajar indicator system consists of the following components:
• | The body control module (BCM) |
• | The instrument panel cluster (IPC) |
• | The driver information center (DIC) |
• | The passenger door latch |
• | The left rear door latch |
• | The right rear door latch |
Driver and Passenger Door Ajar Operation
The body control module (BCM) receives a discrete input from the respective door latch to indicate the status of the door. The BCM then communicates this status to the instrument panel cluster (IPC) via a serial data message. The IPC, upon receipt of this
serial data message, will illuminate the appropriate ajar message in the driver information center (DIC) and also send a serial data message to the radio to activate the door ajar audible warning when the following conditions are met:
• | The transmission is removed from PARK. |
• | The vehicle speed is greater then 8 km/h (5 mph). |
