Grand Caravan V6-3.8L VIN L (2007)
A non-calibrated OCM is the only component of the Occupant Classification System (OCS) that is available for separate service replacement. The OCS
components of the passenger side front seat cushion including the seat weight bladder and pressure sensor, seat cushion foam, wiring harness and the
OCM are a factory-calibrated and assembled unit. Once this unit is connected to a vehicle electrically, the calibration settings are uploaded from the
calibrated OCM and stored in the memory of the Occupant Restraint Controller (ORC). If only the OCM is subsequently replaced, the new,
non-calibrated OCM learns the proper calibration settings from the ORC after it is connected to the vehicle electrically.
The OCM cannot be adjusted or repaired and, if damaged or faulty, it must be replaced. The components of the passenger front seat cushion are serviced
only as a factory-calibrated, assembled and tamper-evident unit. Only the OCM and the seat cushion trim are available for separate service replacement.
Once a service replacement package has been installed in a vehicle, the OCM can thereafter be serviced only by replacing the entire passenger front seat
cushion with an OCS Service Kit replacement.
