OCCUPANT CLASSIFICATION SYSTEM
OCCUPANT CLASSIFICATION SYSTEM : System Description
SYSTEM DIAGRAM
DESCRIPTION
The occupant classification system (OCS) identifies different size occupants, out of position occupants, and detects if child seat is present in the front passenger seat. The OCS control unit (2) receives inputs from the occupant classification sensors (1) (located on the passenger seat track assembly). Depending on classification of the passenger, the OCS sends a signal to the air bag diagnosis sensor unit. The air bag diagnosis sensor unit uses this signal and the seat belt buckle switch RH signal to determine deployment or non deployment of the passenger front air bag in the event of a collision. Depending on the signals received, the air bag diagnosis sensor unit can disable the passenger front air bag completely. The OCS (weight sensors) must be set to zero point using CONSULT after servicing the OCS system.
NOTE:
Passenger Air Bag Status Conditions
NOTE: Passenger does not meet Occupant Classification System specifications for passenger air bag activation.
