Seat Belt, Lights-on and Key-In Ignition Warning System

Key-In Ignition Warning
When the key remind switch is closed, battery voltage is applied to the RED wire of the warning buzzer control unit. With the driver's door open, ground is provided at the BLK/GRN wire of the warning buzzer control unit and the warning buzzer control unit sounds.

Seat Belt Warning
With the ignition switch in ON or START, battery voltage is applied to the seat belt warning light from fuse 7. With the driver's seat belt unbuckled, the warning buzzer control unit senses ground at the GRN/ORN wire. With the ignition key in the ON position, the seat belt warning light turns ON for four to eight seconds. Also if the driver's seat belt is unbuckled, the warning buzzer control unit will sound for the same amount of time.

Lights-on Warning
When the ignition key is turned to the OFF position and the park lights are ON, the light switch applies battery voltage to the warning buzzer control unit at the GRN/RED wire. The warning buzzer control unit will sound until the lights are turned OFF.
