Circuit Description
The body control module (BCM) controls the operation of the fasten safety belt indicator. The fasten safety belt indicator is located in the instrument cluster. The BCM turns ON the fasten safety belt indicator by sending voltage through the seat belt indicator supply voltage circuit. The fasten safety belt indicator receives ground through the ground circuit.
The BCM turns ON the fasten safety belt indicator for 55 seconds when the following conditions are met:
- The ignition is ON
- The driver unbuckles the seat belt
If the driver seat belt is fastened during the 55 second period, the BCM turns OFF the fasten safety belt indicator. If the driver's seat belt releases anytime during the same ignition cycle, the BCM turns ON the seat belt indicator again for 55 seconds.
