Fasten-Belts Indicator Control

The BCM turns on the fasten-belts indicator for 63-77 seconds by sending B+ through CKT 529 when the following conditions are met:
^ The ignition switch is in the RUN position.
^ The driver seat belt is unfastened (ground signal in CKT 238).
If the driver fastens the seat belt during the 70-second period, the BCM turns oft the indicator. If the driver unfastens the seat belt during the same ignition cycle, the BCM repeats the cycle, turning on the fasten-belts indicator for an additional 63-77 seconds.
