Seat Occupant Classification Module - Air Bag: Description and Operation
Description
DESCRIPTION
The Occupant Classification Module (OCM) is secured with two screws to a mount on the underside of the passenger side front seat cushion frame near
the outboard front corner. Concealed within a hollow in the center of the molded plastic OCM housing is a microprocessor and the other electronic
circuitry of the module. The module housing is sealed to enclose and protect the internal electronic circuitry. The OCM software is flash programmable.
A non-calibrated OCM is available for service replacement. The OCM and all of the other components of the Occupant Classification System (OCS)
including the passenger front seat, the seat weight sensors, the passenger or driver seat track position sensor and the seat adjusters, cushion, back, frame,
foam, springs, and wiring harness are a factory-calibrated and assembled unit. Any time any one of these components is removed or replaced for any
reason, the OCM must be re-calibrated using a diagnostic scan tool, the Occupant Classification Seat Weight special tool, and the Occupant
Classification System Verification Test. Refer to the appropriate diagnostic procedures.
The OCM cannot be adjusted or repaired and, if damaged or faulty, it must be replaced.
