U0455Invalid Data Received From Restraints Occupant Classification System Module
- Generic OBD-II code · Network
- How the car detects it
- The occupant classification module reads sensors in the front passenger seat and reports to the restraints controller if the seat is vacant, occupied by a child seat or by an adult; FMVSS 208 lets carmakers switch the passenger airbag off automatically on that basis. U0455 means the restraints controller still receives this classification but finds it invalid, whereas U0154 is total loss of contact. Ford uses the code in the RCM: SSM 46109 and SSM 46901 concern Fusion and MKZ of model years 2017-18 showing an airbag lamp or a SYNC 911 Assist warning, list U0455 among other RCM codes and have the RCM reprogrammed and its as-built data loaded again. Chrysler's restraint fault list in NHTSA file PE11-019 keeps a separate code for an undetermined classification. Expect the airbag lamp and doubtful passenger airbag status; no MIL.
