Code B1BBD Mitsubishi Description
The B1BBD code for Mitsubishi vehicles indicates that the Occupant Classification Module (OCM) current table is unprogrammed. The OCM is a crucial component of the vehicle's safety system, responsible for determining the weight and position of occupants in the front passenger seat to control airbag deployment. When the OCM current table is unprogrammed, it means that the module is not properly calibrated to accurately detect occupants, potentially leading to incorrect airbag deployment or failure to deploy in the event of a crash.
Common Causes of B1BBD Mitsubishi
- Software glitch or malfunction in the OCM.
- Electrical connection issues or wiring problems.
- Impact or damage to the OCM sensor.
- Faulty OCM module.
- Incorrect calibration or programming of the OCM.
Symptoms of B1BBD Mitsubishi
- Airbag warning light illuminated on the dashboard.
- Inconsistent or erratic airbag deployment.
- Passenger airbag off indicator staying illuminated.
- Fault codes related to the OCM in the vehicle's diagnostic system.
- Inability to pass state inspections due to safety system issues.
How to Fix B1BBD Mitsubishi
- Connect a diagnostic scanner to the vehicle's OBD-II port to retrieve the specific fault code and confirm the issue.
- Inspect the OCM wiring and connections for any damage or corrosion, repairing or replacing as necessary.
- Program or reprogram the OCM module using manufacturer-specific software to calibrate the current table accurately.
- Test the OCM system to ensure proper functionality and clear any fault codes from the vehicle's system.
- Perform a final test drive to verify that the airbag warning light is no longer illuminated and that the OCM is operating correctly.
Cost to Fix B1BBD Mitsubishi
The cost of repairing an unprogrammed OCM current table in a Mitsubishi vehicle can vary depending on the extent of the issue and the specific repairs needed.

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.
