System Outline

Current is always applied from the ECU-B fuse to TERMINAL 3 of the combination meter. When the ignition SW is turned to the ON position, the current from the MET IG2 fuse flows to TERMINAL 4 of the combination meter.

Seat Belt Warning System 

When the ignition SW is turned on, a signal is sent to the combination meter. To determine whether the driver has fastened the seat belt, a signal is sent from the front seat inner belt (Driver's side) to TERMINAL 5 of the combination meter. If the seat belt is not fastened, the seat belt warning light in the combination meter blinks, and emits a warning sound.

In addition, if a front passenger is detected by the sensor (Occupant detection sensor) which is installed in the front passenger seat, it is then determined whether the passenger's seat belt is fastened or not. If not fastened, the signals from the front seat inner belt (Front passenger's side) are sent to TERMINAL 22 of the combination meter, and the passenger's seat belt warning lamp blinks.
