Code B220C Description

The B220C diagnostic trouble code refers to an issue with the Occupant Restraint Controller Accelerometer 1 Internal. The Occupant Restraint Controller (ORC) is a crucial component of the vehicle's safety system, responsible for managing the operation of the airbags and seat belt pretensioners. The accelerometer within the ORC is designed to detect sudden changes in vehicle acceleration and trigger the deployment of airbags in the event of a collision.

Precautions for SRS “AIR BAG” and “SEAT BELT PRE-TENSIONER” Service

  • Never probe the electrical connectors on air bag, side air curtain modules or seat belts.
  • Never disassemble or tamper with safety belt buckle/retractor pretensioners, adaptive load limiting retractors, safety belt inflators, or probe the electrical connectors.
  • Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
  • Before servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3 minutes. For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes have passed.

Failure to follow this instruction may result in the accidental deployment of these modules, which increases the risk of serious personal injury or death.
