Code B220D Description

When powered, the Occupant Restraint Controller (ORC) performs an internal self test. The repair of this fault condition does not involve any external circuitry and centers on verifying the integrity of the module's internal circuitry and software validity. When Monitored the ORC module on board diagnostics continuously performs internal circuit tests. This Diagnostic Trouble Code (DTC) will set if the module identifies an out of range internal circuit.

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.
