Door Ajar Indicator
2000 Chevrolet Malibu V6-3.1L VIN JSECTION Door Ajar Indicator
This is a distributed function. The door ajar indicator (red) will indicate to the driver that one or more of the vehicle doors are open when the ignition switch is turned to the ON position. The opening of the door(s) will also cause a chime. The door ajar indicator and the chime will be turned OFF when all of the doors are closed. The BCM will perform the following functions:
1. Read the status of all of the door inputs
2. Determine the indicator control
3. Send the control state to the instrument cluster in a SPI message.
The instrument cluster will read the door ajar indicator control bit in the SPI message and control the indicator directly. In the event of the loss of the SPI interface with the BCM, the instrument cluster will turn the door ajar indicator OFF.
