SEAT BELT WARNING SYSTEM - Front Passenger Side Seat Belt Warning Light Malfunction


DESCRIPTION

The combination meter detects the state of the front seat inner belt assembly (for Front Passenger Side) when the front passenger seat is occupied with the ignition switch ON. If the front passenger seat belt is not fastened, the front passenger side seat belt warning light on the multi-media module receiver assembly*1 (clock assembly*2) blinks. If the seat belt is fastened, the warning light goes off.
