Occupant Classification System (OCS)
WARNING: This page is about a different car, the 2009 Nissan Maxima. However, it is still accessible from the selected car via links, so may be relevant.
The occupant classification system (OCS) identifies if a child or child seat is present in the front passenger seat. The OCS receives inputs from the occupant classification sensor mat (1) which is located inside the passenger seat cushion assembly. Depending on classification of the passenger, the OCS control unit (2) 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 front passenger air bag module in the event of a collision. Depending on the signals received, the air bag diagnosis sensor unit can disable the front passenger air bag module completely.
NOTE:
In case of customer concern, CONSULT-III can be used to confirm the front passenger air bag status (readiness).
