Purpose
The seat belt warning alarm warns occupants that a seat belt is not fastened.
Function
The instrument cluster sounds the seat belt warning alarm based on the following CAN signals:
Vehicle speed signal sent from PCM
Driver/passenger buckle switch signal, occupancy sensor signal sent from SAS control module
Driver/passenger seat belt warning alarm sound function
The driver/passenger seat belt warning alarm 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 have been met, the alarm sounds.
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 alarm only)
The driver/passenger seat belt warning alarm sound pattern is as shown in the figure.

When all of the following conditions are met, the alarm sounds.
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 alarm only)
The driver/passenger seat belt warning alarm sound pattern is as shown in the figure.

When all of the following conditions are met, the alarm sounds.
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 alarm only)
After initial warning operates, buckle switch off signal (seat belt fastened) to on signal (seat belt unfastened) is detected
The driver/passenger seat belt warning alarm sound pattern is as shown in the figure.

Construction
The seat belt warning alarm sounds using the buzzer built into the instrument cluster.
Operation
1. The instrument cluster receives (1) the vehicle speed signal from the PCM, the driver/passenger buckle switch signal and occupancy sensor signal from the SAS control module when the ignition is switched ON (engine off or on).
2. The instrument cluster microcomputer turns the transistor on (2) based on each signal.
3. When the transistor turns on, a ground circuit with the alarm is established and the alarm sounds (3).
