Code B220D Dodge Description
The B220D diagnostic trouble code for Dodge vehicles specifically refers to an issue with the Occupant Restraint Controller Accelerometer 2 internal circuit. The Occupant Restraint Controller (ORC) is a crucial component of the vehicle's safety system, responsible for monitoring and controlling the deployment of airbags and seat belt pretensioners in the event of a collision. The accelerometer within the ORC is designed to detect sudden changes in acceleration and trigger the appropriate safety measures to protect the occupants.
Common Causes of B220D Dodge
- Faulty ORC accelerometer sensor.
- Wiring or connection issues in the ORC system.
- Impact or damage to the ORC unit.
- Electronic control module (ECM) malfunction.
- Software glitches or calibration errors.
Symptoms of B220D Dodge
- Illumination of the airbag warning light on the dashboard.
- Inconsistent or improper deployment of airbags in the event of a collision.
- Failure to trigger seat belt pretensioners during sudden deceleration.
- Safety system malfunctions during diagnostic tests.
How to Fix B220D Dodge
- Use a diagnostic scanner to read and clear the B220D code.
- Inspect the ORC system for any visible damage or loose connections.
- Test the ORC accelerometer sensor for proper functioning.
- Replace the faulty ORC accelerometer sensor if necessary.
- Reset the airbag system and perform a test drive to ensure proper operation.
Cost to Fix B220D Dodge
The typical repair costs for addressing the B220D code may range from $200 to $500, including parts and labor.

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.
