Code B1B83 Mitsubishi Description
The B1B83 code in a Mitsubishi indicates a problem with the passenger seat weight sensor 2 left rear input circuit being too low. This sensor is crucial for the proper functioning of the vehicle's airbag system, as it helps determine whether or not to deploy the airbag in the event of a crash. When the sensor detects a passenger in the seat, it adjusts the airbag deployment settings accordingly to ensure their safety. A low input circuit reading suggests that there may be an issue with the sensor or its wiring, which could potentially lead to improper airbag deployment or no deployment at all.
Common Causes of B1B83 Mitsubishi
- Faulty passenger seat weight sensor
- Damaged wiring or connectors in the sensor circuit
- Corrosion or water damage affecting the sensor
- Issues with the airbag control module
- Electrical issues in the vehicle's wiring system
Symptoms of B1B83 Mitsubishi
- Airbag warning light illuminated on the dashboard
- Inconsistent or erratic airbag deployment
- Passenger seatbelt warning light staying on
- Passenger airbag off indicator showing despite a passenger in the seat
- Loss of communication with the airbag control module
How to Fix B1B83 Mitsubishi
- Begin by diagnosing the specific cause of the low input circuit reading, which may involve using a scan tool to retrieve fault codes and data from the airbag control module.
- Inspect the passenger seat weight sensor and its wiring for any visible damage or corrosion. Replace the sensor if necessary.
- Check and repair any damaged wiring or connectors in the sensor circuit.
- Clear the fault codes from the airbag control module and reset the system to ensure proper functioning.
- Test the airbag system to verify that the issue has been resolved and that the airbags deploy correctly.

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.
