Code B220C Dodge Description
The B220C code for Dodge vehicles indicates a problem with the Occupant Restraint Controller Accelerometer 1 internal circuit. The Occupant Restraint Controller (ORC) is responsible for controlling the airbag system and seatbelt pretensioners in the vehicle. The accelerometer is a sensor that detects changes in acceleration and deceleration, providing crucial information to the ORC for deployment of safety systems in the event of a collision. When this code appears, it means that there is a malfunction in the internal circuit of the accelerometer, which could compromise the proper functioning of the airbag system and seatbelt pretensioners.
Common Causes of B220C Dodge
- Faulty accelerometer sensor
- Wiring or connector issues in the circuit
- Electronic control module malfunction
- Impact or collision that damaged the sensor or circuit
- Environmental factors like moisture or corrosion affecting the sensor
Symptoms of B220C Dodge
- Airbag warning light illuminated on the dashboard
- Inability to deploy airbags in a collision
- Seatbelt pretensioners not engaging properly
- Erratic behavior of the airbag system
- Vehicle failing safety inspections due to airbag system issues
How to Fix B220C Dodge
- Diagnose the specific cause of the B220C code using a diagnostic scan tool
- Inspect the wiring and connectors related to the accelerometer circuit for any damage or corrosion
- Replace the faulty accelerometer sensor if necessary
- Clear the code from the vehicle's computer system
- Perform a test drive to ensure the airbag system is functioning correctly
Cost to Fix B220C Dodge
The cost of repairing the B220C code in a Dodge vehicle can vary depending on the specific cause of the issue. In general, replacing a faulty accelerometer sensor and addressing any wiring or connector issues can 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.
