Front Passenger Side Seat Belt Warning Light Malfunction

DESCRIPTION

When the ignition switch is ON and the front passenger seat is occupied, the center airbag sensor assembly communicates the status of the front seat inner belt assembly RH to the main body ECU using the CAN communication line. The main body ECU receives signals from the center airbag sensor assembly and transmits them to the combination meter assembly. When the front passenger seat belt is unfastened, the combination meter assembly flashes the front passenger seat belt warning light on the instrument panel finish panel end RH. When the seat belt is fastened, the combination meter assembly stops flashing the front passenger seat belt warning light on the instrument panel finish panel end RH.
