SYSTEM DESCRIPTION

1. GENERAL

(a) In the occupant classification system, the occupant detection ECU calculates the weight of the occupant based on signals from the occupant classification sensors. This system recognizes the occupant as a child if it detects a weight of less than 36 kg (79.3 lb), and disables the front passenger airbag, front passenger side knee airbag and front seat belt pretensioner RH.

(b) This system is mainly comprised of 4 occupant classification sensors that detect the load on the front passenger seat. The occupant detection ECU controls the system, and the passenger airbag ON/OFF indicator indicates the ON/OFF condition of the front passenger airbag, front passenger side knee airbag and front seat belt pretensioner RH.
