DESCRIPTION OF OPERATION
Seat-belt Warning
When the ignition switch is in the Drive position, driver seat-belt warning switch 70D is supplied with current from fuse 3 via seat-belt warning
lamp 72. The switch grounds the warning lamp which then lights up. When the seat belt is inserted in the seat-belt buckle the switch opens and the
lamp goes out.
Connected in series with passenger seat-belt switch 70P is seat switch 69D which closes when the seat is occupied. The warning lamp is activated
only when the passenger seat is occupied and the occupant has not fastened the seat belt.
Seat-belt Warning With Buzzer And Ignition Key Warning
The warning system alerts the driver if the seat belt is not fastened or if the car is left with the key in the ignition.
The system incorporates warning relay 82 which has a buzzer. When the ignition switch is in the Drive position, the relay is supplied with positive
current via fuse 13.
Seat-belt Warning
When the ignition switch is in the Drive position, positive current is also supplied from fuse 3 via seat-belt warning lamp 72 to the warning
relay.
If the belt is not fastened, the relay will be grounded by driver seat-belt warning switch 70. The warning lamp then lights up at the same time as
the buzzer sounds. When the seat-belt is inserted in the seat-belt buckle, the switch opens and turns off the lamp and buzzer.
Ignition Key Warning
As long as the key remains in the ignition switch, current will be supplied from ignition switch terminal B to the warning relay.
If the key is still in the ignition switch when the driver's door is opened, door switch 54 will close. This grounds terminal 1, thus turning on the
buzzer.
FAULT DIAGNOSIS HINTS
Activation of the seat-belt and ignition key warning takes place when the ignition switch is in the Drive position.
