Seat Belt Warning System System Description

When the driver seat belt is not fastened with the ignition switch ON, the driver seat belt warning light on the combination meter assembly comes on to inform the driver. The center airbag assembly detects the driver seat belt condition and sends signals to the body ECU and the meter assembly via CAN communication.

When the passenger seat belt is not fastened with ignition switch ON and the passenger seat occupied, check that the passenger seat belt warning light on telltale light blinks. The occupant detection sensor detects if the passenger seat is occupied and sends signals to the combination meter assembly. The inner belt detects the passenger seat belt condition and sends signals to the combination meter assembly. After receiving the signals from the occupant detection sensor and inner belt, the meter assembly sends signals to telltale light to request the passenger seat belt warning light to blink or go off.
