Occupant Classification System (OCS)NHS0009O
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 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 classifi-
cation of passenger, the occupant classification system sends a signal to the diagnosis sensor unit. The diag-
nosis sensor unit uses this signal to determine full, partial, or non deployment of passenger front air bag in the
event of a collision. Depending on the signal received, the diagnosis sensor unit can disable the passenger
front air bag completely.
NOTE:
In case of customer concern, CONSULT-ll can be used to confirm the passenger air bag status (readiness).
