This information is used to control the deployment of the airbag system and ensure that it deploys with the appropriate force based on the occupant's characteristics.
Common Causes of B2212 Chrysler
- Faulty Occupant Classification Module (OCM).
- Wiring or connector issues in the OCM circuit.
- Software glitches or malfunctions in the OCM.
- Impact or damage to the OCM due to accidents or rough handling.
- Corrosion or moisture damage affecting the OCM components.
Symptoms of B2212 Chrysler
- Airbag warning light illuminated on the dashboard.
- Inconsistent or incorrect airbag deployment in a crash.
- Passenger airbag indicator showing incorrect status.
- Safety system warning messages displayed on the instrument cluster.
- Vehicle failing safety inspections due to airbag system issues.
How to Fix B2212 Chrysler
- Begin by diagnosing the specific cause of the B2212 code using a diagnostic scanner to pinpoint the issue within the OCM.

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.
