DESCRIPTION OF OCCUPANT CLASSIFICATION SYSTEM
GENERAL DESCRIPTION
In the occupant classification system, the occupant classification ECU calculates the weight of the occupant based on signals from the occupant classification sensors.
This system is mainly comprised of 4 occupant classification sensors that detect the load on the front passenger seat. The occupant classification ECU controls the system, and the passenger airbag ON/OFF indicator indicates the ON/OFF condition of the front passenger airbag and front seat belt pretensioner RH.
OCCUPANT CLASSIFICATION SENSOR
The occupant classification sensors are installed on 4 brackets connecting the seat rail and seat frame. Accordingly, when load is applied to the front passenger seat by an occupant sitting in it, the occupant classification sensors register a distortion.
DESCRIPTION FOR PASSENGER AIRBAG ON/OFF INDICATOR
This indicator informs the driver whether the occupant classification ECU puts the front passenger airbag and front seat belt pretensioner RH into an active state or inactive state.
If a malfunction occurs in the occupant classification system, the SRS warning light come on.
