Warning Systems: Operation

Battery voltage for module operation is supplied by fuse No. 15 in the fuse block module. See Fig 1 and Fig 2 . It also receives a second battery feed from fuse No.17 when the ignition switch is in the RUN or START position.

The seat belt warning system uses both visual and audible signals. These consist of a buzzer that is part of a combined seat belt and key warning buzzer and a Red light on the instrument panel.

The system will always illuminate the seat belt warning lamp for four to eight seconds when the ignition switch is turned to the ON position. Also, only if the driver does not fasten his seat belt, the buzzer will sound during the same time interval. Passenger belts are not connected to the system.

A timed buzzer relay is used to operate the system for the time period. It has a time delay mechanism and buzzer assembly. Only the driver's seat belt buckle has a switch that is connected to the system.

To sound the "key in ignition" alarm, both the ignition key warning switch and the driver's door jamb switch must be closed. This condition grounds pin No. 6 of the module. These switches are closed when the driver's door is open and the key is in the ignition or headlamps are on.
