OCCUPANT CLASSIFICATION SY STEM : System DescriptionINFOID:0000000009460720
The occupant classification system (OCS) identifies diff erent size occupants, out of position occupants, and
detects if a child seat is present in the front passenger seat. The OCS control unit (2) receives inputs from the
occupant classification sensors (1) (located inside t he passenger seat cushion assembly). Depending on clas-
sification 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 (passenger seat) 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 dis able the passenger front air bag completely. The OCS
(weight sensors) must be set to zero point using CONSULT after servicing the OCS system.
NOTE:
• CONSULT can be used to confirm when “zero point reset” for OCS is complete.
• Always perform zero point reset after the removal and installation of the seat or when disconnecting the
OCS control unit harness connector even if zero point reset has been completed in the past.
• If zero point reset is incomplete, the passenger air bag will be disabled and the passenger air bag off indica-
tor will be ON.
• In case of customer concern, CONSULT can be us ed to confirm the passenger air bag status (readiness).
