Occupants Classification System (OCS) - North America Vehicles

WARNING: This page is about a different car, the 2008 Suzuki Swift +, 2008 Pontiac Wave, and 2008 Chevrolet Aveo. However, it is still accessible from the selected car via links, so may be relevant.

OCS determines passenger airbag deployment. It consists of a sensor and module which are in the passenger seat.

OCS monitors the pressure profile of the passenger seat and sends it to the sensing and diagnostic module (SDM).

When the pressure from the occupant's weight is higher than a specified value, the OCS module will send an enable signal to the SDM to deploy the passenger airbag.

When the passenger airbag on and off indicators are lit on the passenger airbag status indicator, it indicates the suppression of deployment for the passenger's frontal airbag and side airbag.

When the passenger seat cushion assembly is replaced, besure to confirm that the OCS operates normally as follows:

Turn the ignition switch ON.
Check the passenger airbag on and off indicators in clock illuminate for 5 seconds and turn off for 2 seconds. If the both indicators turn on or off depending on the status of passenger presence after step 2, OCS is in good condition.

OCS is not unit repairable so it should be replaced with an assembly of passenger seat cushion.
