Driver Side Seat Belt Warning Light does not Operate

DESCRIPTION

When the ignition switch is turned to ON, the center airbag sensor transmits front seat inner belt LH*1 (or RH*2) state signals to the combination meter through the CAN. If the driver side seat belt is not fastened, the combination meter blinks the front seat belt warning light. If the seat belt is fastened, the warning light goes off.

Tech Tips

The front seat belt warning light on the combination meter assembly is used for both the driver side seat and front passenger side seat.
