SYSTEM DESCRIPTION
1. FRONT PASSENGER OCCUPANT CLASSIFICATION SYSTEM
a. General Description
1. The front passenger occupant classification system determines whether the front passenger seat is occupied by an adult or child (with child
seat) or is unoccupied, based on the load that is applied to the front passenger seat and whether the seat belt is buckled. The system restricts
the deployment of the front passenger airbag, front passenger side airbag, and the front passenger seat belt pretensioner in accordance with
this judgement. The result is informed to the driver through the airbag ON/OFF indicator illumination.
b. System Configuration
1. This system consists of the occupant classification ECU, occupant classification sensors, airbag ON/OFF indicator, seat belt buckle
switches, and center airbag sensor assembly.
