Seat Belt Warning System

When the ignition switch is turned to the ON position, the signal is input to the appropriate body ECU and door ECU. At this time, to determine whether or not the driver fastens the seat belt, the signal from the LH buckle switch is input to terminal DBKL of the body ECU No. 2. If the driver does not fasten the seat belt, the seat belt warning light in the combination meter flashes and the alarm buzzer goes on, in response to the communication control of the appropriate body ECU and door ECU etc.

Additionally, the sensor (seat belt warning occupant detection sensor) installed on the front passenger seat detects the passenger and determines whether or not the passenger fastens the seat belt.

If the passenger does not fasten the seat belt, the signals from the seat sensor and RH buckle switch are input to terminal RBE+ of the center air bag sensor assembly and through communication control of the appropriate body ECU and door ECU etc. The passenger seat belt warning light in the clock is flashed.
