Occupant Classification System (OCS)

INFOID:0000000009479959

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 receives inputs from the occupant classi-

fication sensor (located inside the passenger seat cushion assembly) and belt tension sensor (part of the pas-

senger front seat belt assembly and located at the belt anchor location). 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.

NOTE:

In case of customer concern, CONSULT can be used to confirm the passenger air bag status (readiness).
