Bladder Repair Kit

There are only three replaceable components in the OCS, Occupant Classification Module, Bladder Repair Kit and the Passenger Airbag OFF Indicator. The Bladder repair kit contains the OCS bladder; wire harnesses, pressure sensor (Seat Weight Sensor), module, seat cushion and other relate structural and sound deadening components. The module and sensor connector have a Tamper evident material installed on the service kit module and sensor connectors. This material provides visible evidence that the assembly has been separated after the calibration process was completed. Do not install a Bladder Repair Kit if it appears that any of the components have been disconnected

The OCM can be replaced if the Airbag Control Module has uploaded the seat calibration into memory in a previous ignition cycle and the new OCM has a blank VIN and no calibration data stored in memory.

NOTE: An OCM can only be replaced in a passenger front seat if the seat is equipped with the original OCS module, bladder, sensor and wiring.

NOTE: Servicing the OCS may create additional active and stored trouble codes that must be resolved before the vehicle can be returned to the owner. The OCS Verification Test will also set active DTCs if the procedure is not completed successfully.

The Miller Special Tool, MRL-9077 and the DRB®III are needed to successfully complete the system Verification Test. The DRB may report the following errors and failure messages during the procedure.
