  1. GENERAL 
    1. The occupant detection ECU estimates the weight of an occupant based on signals received from the 2 occupant classification sensors. The occupant detection ECU determines whether the front passenger seat is occupied and classifies the occupant based on the estimated weight, front passenger side buckle switch state, acceleration sensor signal and vehicle speed signal. The result determined by the occupant detection ECU is sent to the airbag ECU assembly via CAN communication.
    2. The airbag ECU assembly controls the operation of the passenger airbag ON/OFF indicator and restricts the operation of the instrument panel passenger airbag assembly and lower No. 2 instrument panel airbag assembly.
