Occupant Classification System (OCS)

The OCS classifies the size of the front passenger seat occupant and provides this information to the RCM.

Pressure is applied to the OCS bladder when weight of any occupant or object in the front passenger seat is present. The pressure is then transferred through a tube and sensed by the OCS pressure sensor within the OCSM. The OCSM sends information concerning the weight of any occupant or object on the front passenger seat to the RCM via the HS-CAN2. The RCM uses this information when determining if the passenger airbag needs to be deployed in the event of a crash.

The OCS is also used for operation of the passenger Belt-Minder ®. Refer to: Seatbelt Systems - System Operation and Component Description . To deactivate or reactivate the passenger Belt-Minder ® feature, Refer to: Seatbelt Minder Deactivating/Activating .

Passenger Airbag Deactivation (PAD) Indicator 

The RCM controls the PAD indicator through a direct, hardwired connection, based on information provided by the OCS. The PAD indicator illuminates to indicate whether the passenger airbag is disabled or enabled.

The RCM briefly activates the PAD indicator to prove out the indicator function and verify proper functional operation of the PAD indicator to the front occupants.

The following table indicates the passenger airbag and PAD indicator status based on the size of the front passenger occupant.
