U0455Invalid Data Received From Restraints Occupant Classification System Module

U0455 means the module that monitors the occupant classification system (OCS) in the seats has sent data the vehicle's network considers invalid, so the restraint control module cannot trust the passenger presence or weight information. The computer detected a message from the OCS module that was missing expected values, out of range, or not properly formatted for the network.
