- SEAT BELT WARNING SYSTEM DESCRIPTION
- Driver seat belt warning light operation:
The seat belt warning light on the combination meter assembly illuminates, blinks or turns off in accordance with the driver seat belt state, vehicle speed, shift lever position and parking brake state.
- Front passenger seat belt warning light operation:
The seat belt warning light on the combination meter assembly illuminates, blinks or turns off in accordance with whether the front passenger seat is occupied, the passenger seat belt state, vehicle speed, shift lever position and parking brake state.
- Seat belt warning buzzer:
After turning the engine switch on (IG), if the driver seat belt is not fastened within 1.8 seconds, check that the seat belt warning buzzer in the combination meter assembly sounds at 1.2 seconds intervals for 6 seconds.
When the vehicle is driven at 20 km/h (12 mph) or more with the front passenger seat occupied and the driver or front passenger seat belt not fastened, the seat belt warning buzzer in the combination meter assembly sounds once.
When 30 seconds have passed after the buzzer sounded, the seat belt warning buzzer in the combination meter assembly sounds at an interval of 1.2 seconds for 9.6 seconds.
After that, the seat belt warning buzzer in the combination meter assembly sounds at an interval of 0.4 seconds for 20 seconds.
- Driver seat belt warning light operation:
- FUNCTION OF MAIN COMPONENTS
Component Function Front seat inner belt assembly LH Informs the airbag ECU assembly of the driver seat belt condition (fastened or unfastened). Front seat inner belt assembly RH Informs the occupant detection ECU of the front passenger seat belt condition (fastened or unfastened). Occupant classification sensor LH/RH Informs the occupant detection ECU of the front passenger seat condition (occupied or unoccupied). Combination meter assembly - The combination meter assembly illuminates, blinks or turns off the seat belt warning light.
- The combination meter assembly sounds the seat belt warning buzzer.
Occupant detection ECU Sends the front passenger seat belt buckle switch signal and occupant detection signal to the airbag ECU assembly. Airbag ECU assembly - Sends the driver seat belt buckle switch signal to the main body ECU (multiplex network body ECU) via CAN communication.
- Sends the front passenger seat belt buckle switch signal to the combination meter assembly via CAN communication.
Main body ECU (multiplex network body ECU) Sends the driver seat belt buckle switch signal and parking brake switch signal to the combination meter assembly via CAN communication. Skid control ECU (brake actuator assembly) Sends the vehicle speed signal to the combination meter assembly via CAN communication. ECM Sends the shift position signal to the combination meter assembly via CAN communication.
