Toyota Venza: System Description

SYSTEM DESCRIPTION

1. DESCRIPTION OF OCCUPANT CLASSIFICATION SYSTEM

(a) GENERAL DESCRIPTION

(1) 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 recognizes the occupant as a child if it detects a weight of less than 32 kg (70.6 lb), and disables the front passenger airbag and front seat belt pretensioner RH.

(2) 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.

(b) OCCUPANT CLASSIFICATION SENSOR


(1) 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.

(c) DESCRIPTION FOR PASSENGER AIRBAG ON/OFF INDICATOR


(1) 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.

(2) If a malfunction occurs in the occupant classification system, the passenger airbag ON/OFF indicator ("OFF") and the SRS warning light come on.
