SEAT BELT – SEAT BELT WARNING SYSTEM
SB
DESCRIPTION
When the ignition switch is ON and the front passenger seat is occupied, the occupant classification ECU
communicates the status of the front seat inner belt assembly (passenger side) to the center airbag
sensor assembly. The combination meter assembly receives signals from the center airbag sensor
assembly and transmits them to the integration control and panel assembly. When the seat belt is
unfastened, the combination meter assembly flashes the front passenger seat belt warning light on the
integration control and panel assembly. When the seat belt is fastened, the combination meter assembly
stops flashing the front passenger seat belt warning light on the integration control and panel assembly.
