Purpose
The seat belt warning light warns the driver that a seat belt is not fastened.
Function
The instrument cluster flashes/illuminates the seat belt warning light based on the following CAN signals:
Vehicle speed signal sent from PCM
Driver/passenger buckle switch signal, occupancy detection sensor signal sent from SAS control module
Driver/passenger seat belt warning light display function
The driver/passenger seat belt warning light has a warning for when the vehicle is stopped, while the vehicle is being driven, and subsequent warnings while the vehicle is being driven.
When all of the following conditions are met, it flashes/illuminates.
Ignition switch ON (engine off or on)
Driver/passenger buckle switch on signal (seat belt unfastened) is detected
Occupancy sensor on signal (occupant in passenger seat) is detected (passenger seat belt warning light only)
The driver/passenger seat belt warning flash/illumination pattern is as shown in the figure.

When all of the following conditions are met, it flashes/illuminates
Vehicle speed is approx. 20 km/h {12 mph} or more
Driver/passenger buckle switch on signal (seat belt unfastened) is detected
Occupancy sensor on signal (occupant in passenger seat) is detected (passenger seat belt warning light only)
The driver/passenger seat belt warning flash/illumination pattern is as shown in the figure.

When all of the following conditions are met, it flashes/illuminates
Vehicle speed is approx. 20 km/h {12 mph} or more
Occupancy sensor on signal (occupant in passenger seat) is detected (passenger seat belt warning light only)
After warning while vehicle is being driven operates, buckle switch off signal (seat belt fastened) to on signal (seat belt unfastened) is detected
The driver/passenger seat belt warning flash/illumination pattern is as shown in the figure.

Construction
The microcomputer in the instrument cluster controls the illumination/flashing/turning off of the seat belt warning light based on the driver/passenger buckle switch signal and occupancy sensor signal from the SAS control module, and the vehicle speed signal from the PCM.
The driver seat belt warning light is set in the instrument cluster.

The passenger seat belt warning light are set in the clock (with manual A/C)/climate control unit (with auto A/C). For details on the passenger seat belt warning light, refer to CLOCK (with manual A/C)/CLIMATE CONTROL UNIT [FULL-AUTO AIR CONDITIONER] (with auto A/C).
Operation
1. The instrument cluster receives (1) a vehicle speed signal from the PCM, and a driver/passenger seat buckle switch signal and occupancy sensor signal from the SAS control module.
2. The instrument cluster microcomputer turns the transistor on (2) intermittently for flashing and continuously for illumination based on the each signal. In addition, it sends a driver/passenger seat belt warning request signal to the clock (with manual A/C)/climate control unit (with auto A/C).
3. When the transistor turns on intermittently, the driver seat belt warning light flashes (3), when it turns on continuously, the driver seat belt warning light illuminates (3).
