Code B2290 Ford Description

The B2290 Ford code indicates a fault in the Occupant Classification System (OCS) of the vehicle. The OCS is responsible for determining whether a passenger is present in the front passenger seat and, if so, their weight and size to determine how the airbag system should deploy in the event of a crash. This system uses sensors in the seat to make these calculations. A fault in the OCS can lead to the airbag not deploying properly, which can pose a safety risk to the occupants in the vehicle.

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.

    • If the airbag light on your 2010 Ford Sport Trac stays on, it indicates an issue with the Supplemental Restraint System (SRS). The system has detected a fault and deactivated the airbags to ensure safety until the issue is resolved. Here’s a brief guide:

      Possible Causes:

      1. Faulty Clock Spring: The clock spring inside the steering wheel can wear out and fail to maintain the electrical connection to the airbag.
      2. Seat Belt Pretensioners: A malfunctioning seat belt pretensioner can trigger the airbag light.
      3. Loose or Damaged Connections: Corroded or disconnected wiring under the seat or in the SRS system can cause this issue.
      4. Failed Airbag Module: The airbag control module might be defective.
      5. Low or Fluctuating Battery Voltage: A weak battery can affect the SRS system.

      Diagnosis Steps:

      1. Scan for Codes: Use an OBDII scanner with SRS capability to retrieve fault codes related to the airbag system.
      2. Inspect Wiring: Check the wiring under the seats and in the steering column for loose or damaged connections.
      3. Test Battery Voltage: Ensure the battery and charging system are in good condition.
      4. Examine the Clock Spring: Check for continuity in the clock spring wiring.

      Repair Steps:

      1. Fix Loose Connections: Secure and clean any corroded or loose connectors in the system.
      2. Replace Faulty Components: Replace any identified faulty parts such as the clock spring, seat belt pretensioners, or airbag module.
      3. Reset the SRS System: After repairs, use a scanner to clear the fault codes and reset the system.

      If you’re not experienced with vehicle electrical systems, it’s best to take your Sport Trac to a qualified technician to ensure the airbags are repaired safely.
