Code B2212 RAM Description
The B2212 RAM code refers to an issue with the Occupant Classification Module (OCM) internal circuitry within the vehicle. The OCM is a crucial component of the vehicle's safety system, responsible for accurately detecting and classifying occupants in the front passenger seat. This information is used to determine the deployment of the airbags in the event of a collision. When the OCM internal circuitry malfunctions, it can lead to inaccurate occupant classification, potentially resulting in improper airbag deployment or failure to deploy in a crash.
Common Causes of B2212 RAM
- Electrical issues such as a short circuit or open circuit in the OCM wiring.
- Faulty sensors within the OCM.
- Physical damage to the OCM module.
- Corrosion or water damage affecting the OCM.
Symptoms of B2212 RAM
- Airbag warning light illuminated on the dashboard.
- Inconsistent or incorrect airbag deployment in testing.
- Passenger airbag indicator showing incorrect status.
- Diagnostic trouble codes related to the OCM.
How to Fix B2212 RAM
- Begin by conducting a thorough diagnostic scan to confirm the B2212 RAM code and identify any additional related codes.
- Inspect the OCM wiring and connectors for any signs of damage or corrosion. Repair or replace as necessary.
- Test the sensors within the OCM to ensure they are functioning correctly. Replace any faulty sensors.
- If the OCM module itself is damaged, it may need to be replaced with a new unit.
- Clear the diagnostic trouble codes and perform a final test to verify that the issue has been resolved.

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.
