Occupant Classification System (OCS)
After an impact event, either front, rear, or side, the OCS system components need to be inspected and replaced if found to be damaged.
This includes:
- Occupant Classification Module (OCM)
- Passenger Airbag Disabled Indicator
- Seat Weight Sensors (4)
WARNING:
Never replace both the Occupant Restraint Controller (ORC) and the Occupant Classification Module (OCM) at the same time. If both require replacement, replace one, then perform the Airbag System test. See DIAGNOSIS AND TESTING before replacing the other. Both the ORC and the OCM store Occupant Classification System (OCS) calibration data, which they transfer to one another when one of them is replaced. If both are replaced at the same time, an irreversible fault will be set in both modules and the OCS may malfunction and result in serious or fatal injury.
Whether replaced or not, the OCS must be re-zeroed to make sure that the system in within proper parameters to sense the occupants weight correctly.
WARNING:
Do not connect the battery negative cable. See DIAGNOSIS AND TESTING . Serious or fatal injury may result if the system test is not performed first.
WARNING:
Following successful completion of the Airbag System test procedure, the Occupant Classification System Verification Test must be done using a scan tool and the appropriate diagnostic information. Serious or fatal injury may result if the system test is not performed.
