When this system malfunctions, it can lead to inaccurate airbag deployment, potentially increasing the risk of injury to occupants.
Common Causes of B2290 Mercury
- Malfunctioning weight sensors in the seats.
- Faulty wiring or connectors in the OCS system.
- Software issues in the OCS control module.
- Physical damage to the seats or sensor components.
- Corrosion or water damage to OCS components.
Symptoms of B2290 Mercury
- Airbag warning light illuminated on the dashboard.
- Inconsistent airbag deployment in crashes.
- Passenger airbag light indicating that it is off when a passenger is present.
- Erratic seat belt warning alerts.
- Unresponsive or malfunctioning seat position sensors.
How to Fix B2290 Mercury
- Diagnose the specific cause of the OCS fault using a diagnostic scanner.
- Inspect and test the weight sensors in the seats for proper functioning.
- Check and repair any damaged wiring or connectors in the OCS system.
- Update or reprogram the OCS control module software if necessary.
- Replace any faulty OCS components, such as sensors or control modules, as needed.
Cost to Fix B2290 Mercury

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.
