Code B220B Dodge Description
The B220B diagnostic trouble code (DTC) pertains to the Occupant Restraint Controller (ORC) system in Dodge vehicles. This code indicates a malfunction related to the firing stored energy, which is a critical component of the vehicle's airbag system. The ORC is responsible for monitoring various sensors and determining when to deploy airbags in the event of a collision. When the B220B code is triggered, it suggests that the ORC has detected an issue with the stored energy required to deploy the airbags effectively.
Common Causes of B220B Dodge
- Faulty Occupant Restraint Controller (ORC) unit.
- Low battery voltage or a weak battery affecting the ORC's operation.
- Damaged or corroded wiring harness connected to the ORC.
- Faulty sensors that provide data to the ORC for airbag deployment.
- Software issues or glitches in the vehicle's onboard computer system.
Symptoms of B220B Dodge
- Airbag warning light illuminated on the dashboard.
- Inoperative airbags during crash tests or deployment scenarios.
- Malfunctioning seatbelt pretensioners.
- Diagnostic scanner indicates the presence of the B220B code.
- Possible erratic behavior of other safety features, such as traction control or stability control systems.
How to Fix B220B Dodge
- Diagnostic Scan: Begin by using an OBD-II scanner to confirm the presence of the B220B code and check for any additional codes that may provide more context.
- Visual Inspection: Inspect the wiring harness and connectors associated with the ORC for any signs of damage, corrosion, or loose connections.
- Battery Check: Test the vehicle's battery voltage to ensure it is within the acceptable range, as low voltage can affect the ORC's performance.
- Component Testing: If necessary, test the ORC and related sensors using specialized diagnostic equipment to determine if they are functioning correctly.
- Replacement or Reprogramming: Depending on the findings, replace the faulty components (such as the ORC or sensors) or reprogram the vehicle's computer system if a software issue is identified.
Cost to Fix B220B Dodge

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.
