Recommendations for Salvage Rebuilders

  1. Visual Inspection: Start with checking all connectors, wiring harnesses, and components for physical damage.

  2. Use Professional Repair Services: For faulty modules and seat belts, consider using MyAirbags to repair or reset components, ensuring they meet safety standards.

  3. Reset Procedures: After repairs, use a compatible scan tool to clear codes and reset the SRS system.

  4. Refer to Service Manuals: Always consult the specific Ford service manual for the vehicle's year and model for detailed diagnostics and repair procedures.

  5. Safety Precautions: Disconnect the battery and wait at least 3 minutes before working on SRS components to prevent accidental deployment.


Disclaimer: The codes listed above are generalized and may vary depending on the specific model and year of the Ford vehicle. For precise diagnostics, always refer to the manufacturer's service information or use a professional-grade diagnostic scanner. MyAirbags can help repair and reset specific SRS components, but always ensure that repairs are performed by qualified professionals to maintain vehicle safety.
