Front Passenger Side Seat Belt Warning Light Malfunction
SEAT BELT: SEAT BELT WARNING SYSTEM: Front Passenger Side Seat Belt Warning Light Malfunction
- Front Passenger Side Seat Belt Warning Light Malfunction
DESCRIPTION
w/o Navigation system:
The combination meter detects the state of the front seat inner belt assembly RH when the front passenger seat is occupied with the engine switch on (IG). If the front passenger seat belt is not fastened, the front seat belt warning light on the integration control and panel assembly blinks. If the seat belt is fastened, the warning light goes off.
w/ Navigation system:
The combination meter detects the state of the front seat inner belt assembly RH when the front passenger seat is occupied with the engine switch on (IG). If the front passenger seat belt is not fastened, the front seat belt warning light on the clock assembly blinks. If the seat belt is fastened, the warning light goes off.
