Occupant Classification System (OCS)

Nissan Maxima. Occupant Classification System (OCS)

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 can be used to confirm the front passenger air bag status (readiness).
