Occupant Classification System
The occupant classification system identifies different size occupants, out of position occupants, and detects if child seat is present in the front passenger seat. The occupant classification system receives inputs from the occupant classification system sensor (located inside the passenger seat cushion assembly) and belt tension sensor (part of the passenger front seat belt assembly and located at the belt anchor location). Depending on classification of passenger, the occupant classification system sends a signal to the air bag diagnosis sensor unit. The air bag diagnosis sensor unit uses this signal to determine deployment or non deployment of the passenger front air bag in the event of a collision. Depending on the signal received, the air bag diagnosis sensor unit can disable the passenger front air bag completely. If this occurs the air bag diagnosis sensor unit will turn on the PASS AIR BAG OFF indicator.
