The seat occupied sensor, front passenger side
G128 is only installed in the front passenger seat.
The seat occupied sensor for front passenger side
G128 has no influence on whether the passenger airbag is triggered in the event of an accident.
The function of the front passenger seat occupied sensor
G128 is to remind passengers to wear their seat belt (seat belt command) by means of an optical and acoustic warning signal in the dash panel insert.
On the front passenger side, therefore, corrective activation of the request to fasten seat belt is carried out via the sensor which also evaluates occupancy of the seat and insertion of the seat belt into buckle.
On the driver side, only insertion of the seat belt into buckle is evaluated for corrective activation of the request to fasten the seat belt.
