Occupant Classification Sensor

It uses a pressure mat, weight sensors or capacitive sensors in the seat. It helps prevent deploying the airbag against a child seat or an empty seat. A passenger airbag status lamp shows whether the airbag is on or off.

The module reads the sensor and classifies the occupant before deciding whether the passenger airbag can deploy.

Heavy objects on the seat, seat covers or damage can confuse the sensor. After seat repairs the sensor may need zero-point calibration.
