Code B220D Description
The B220D diagnostic trouble code (DTC) refers to the Occupant Restraint Controller Accelerometer 2 Internal. This code indicates a problem with the accelerometer sensor located within the occupant restraint controller system of the vehicle. The accelerometer is responsible for detecting changes in acceleration and deceleration of the vehicle, which is crucial for the proper deployment of airbags and seat belt pretensioners in the event of a collision.
Common Causes of B220D
- Faulty accelerometer sensor within the occupant restraint controller.
- Wiring or connection issues in the restraint system.
- Impact or damage to the accelerometer sensor due to a collision.
- Software malfunction in the occupant restraint controller system.
Symptoms of B220D
- Illumination of the airbag warning light on the dashboard.
- Inconsistent deployment of airbags or seat belt pretensioners.
- Erratic behavior of the restraint system during sudden acceleration or deceleration.
- Diagnostic trouble code B220D stored in the vehicle's computer system.
How to Fix B220D
- Begin by performing a thorough inspection of the occupant restraint controller system to identify any visible damage or loose connections.
- Use a diagnostic scan tool to retrieve the specific details of the B220D code and pinpoint the exact location of the issue.
- Test the accelerometer sensor for proper functionality and replace it if necessary.
- Check and repair any damaged wiring or connections in the restraint system.
- Clear the DTC from the vehicle's computer system and perform a test drive to ensure that the issue has been resolved.
Cost to Fix B220D
The typical repair costs for addressing the B220D code can vary depending on the extent of the issue and the specific components that need to be replaced. In general, the cost of replacing an accelerometer sensor in the occupant restraint controller system can range from $200 to $500, including parts and labor. However, it is important to note that the actual cost may vary based on factors such as the vehicle make and model, the location of the repair shop, and the hourly labor rates. It is recommended to consult with a professional mechanic to get an accurate estimate for the repair.

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.
