Voltage is available at all times to the seat belts alarm module from the HORN-DM fuse through CKT 40 (ORN). The seat belts alarm module has permanent ground at ground G200. When the ignition switch is in the RUN or START position, voltage is available from the GAUGES fuse through CKT 39 (PNK) to the seat belt alarm.

When the headlamp switch is in the park or headlamp position, voltage is available through the INSTR-LPS fuse through CKT 8 (GRY) to the seat belt alarm. If the module does not receive an ignition signal from the GAUGES fuse, the module sounds the lights on warning.

Because the seat belt switch input has permanent ground at G200, the seat belt warning sounds with the ignition switch in the RUN or START position. The seat belts alarm module supplies voltage to the SEAT BELTS indicator and illuminates for approximately 5 seconds.
