What is B037F?

The DTC code B037F indicates a problem with the driver's side control module, particularly focusing on the seat belt tension sensor. This diagnostic trouble code typically arises when the system detects a malfunction in the sensor that monitors the seat belt's tension during a crash. When the code is triggered, it means that the safety systems may not function as intended, which can have serious implications for passenger safety. For vehicle owners, especially those with models like the 2015-2018 Ford F-150, it's crucial to address this issue promptly. Ignoring it could lead to the airbag system not deploying correctly in the event of an accident, which poses a real risk. Drivers might experience symptoms like the airbag warning light illuminating on the dashboard, or they might notice that the seat belt tension isn't functioning as expected during sudden stops. This can lead to a false sense of security when the vehicle is actually not fully protected. To resolve this issue, professional diagnostics are recommended to ensure that the entire seat belt system is functioning properly, and to replace any faulty components. This code often requires a careful examination of wiring and the seat belt assembly to ensure everything is in good order.

System: B - Body (Airbags, Lighting, Security, Climate Control)

Symptoms

Common symptoms when B037F is present:

  • The airbag warning light stays on continuously, indicating a fault in the airbag system.
  • Seat belt tension feels loose or does not retract properly during sudden stops, reducing safety during a collision.
  • Fuel economy may decrease slightly due to potential electronic system malfunctions that could affect overall vehicle performance.
  • Unexpected error messages may appear on the dashboard, complicating normal vehicle operations.
  • In some cases, the vehicle may not pass safety inspections due to the illuminated warning light.

Possible Causes

Most common causes of B037F (ordered by frequency):

  1. The most common cause of B037F is a faulty seat belt tension sensor, which has a likelihood of around 60%. This sensor can fail due to wear and tear or physical damage, affecting its ability to function correctly.
  2. A second common cause could be damaged wiring or loose connections in the seat belt assembly, which might occur from repeated use or an impact, leading to a 25% likelihood.
  3. Thirdly, software glitches in the vehicle’s onboard diagnostic system can also trigger this code, making up about 10% of cases. Keeping the vehicle's software updated can help prevent these issues.
  4. A less common but serious cause could be a malfunction in the airbag control module itself, which could lead to catastrophic failure of the airbag system during a crash.
  5. Rarely, issues with the vehicle's main ECU, which might affect multiple systems, can also trigger the B037F code, necessitating a thorough inspection.
