Driver-Seat-Belt Switch Input

The BCM determines when the driver seat belt is fastened through the seat belt switch. The seat belt switch opens when the driver fastens the seat belt. When the driver unfastens the seat belt, the seat belt switch closes. This causes the switch to ground CKT 238. The seat belt switch receives ground through CKT 750. The BCM uses this input for the operation of the fasten-belts indicator lamp and the fasten-belts chime reminder.
