What is B07FA?

The diagnostic trouble code B07FA indicates a fault within the brake system control module, often related to issues with the vehicle's electronic stability control (ESC), anti-lock braking system (ABS), or traction control. This code can be triggered by a variety of factors, including wiring problems, faulty sensors, or a malfunctioning control module itself. Car owners may notice that the brake warning light is illuminated on their dashboard, and in some cases, the brakes may feel unresponsive or spongy. In addition, the vehicle may experience reduced braking performance, which can lead to safety concerns. It's crucial to address this code promptly, as neglecting it could lead to more extensive and costly repairs down the line. Regular maintenance and timely diagnostics can help prevent the occurrence of this code, ensuring safe operation of the vehicle. If you own a 2015-2021 Ford F-150 or Jeep Wrangler, keeping an eye on this code is particularly important, as these models are commonly affected.

Symptoms

Common symptoms when B07FA is present:

  • The brake warning light stays illuminated on the dashboard, indicating a potential issue with the braking system.
  • Drivers may notice the vehicle’s brakes feeling unresponsive or less effective during braking, which can be alarming.
  • In severe cases, the vehicle may enter a limp mode, affecting acceleration and overall drivability, especially in emergency situations.
  • The ABS warning light may also activate, suggesting issues with the anti-lock braking system that could compromise safety.
  • Some drivers report a spongy brake pedal feel, which can indicate air in the brake lines or a malfunctioning brake booster.

Possible Causes

Most common causes of B07FA (ordered by frequency):

  1. The most common cause of DTC B07FA is a faulty brake system control module, which is likely to occur in around 40% of cases. This module may fail due to electrical faults or internal malfunctions.
  2. Another prevalent cause is damaged wiring or poor connections within the brake system, accounting for roughly 25% of reported cases. Moisture or corrosion can lead to these wiring issues.
  3. Faulty wheel speed sensors can trigger this code, as they provide critical data to the control module. Keeping these sensors clean and well-maintained can prevent issues.
  4. Less commonly, a brake fluid leak can cause pressure inconsistencies, leading to this error code. Regular checks of brake fluid levels can help prevent leaks.
  5. In rare cases, software glitches in the vehicle’s ECU can also cause B07FA. Ensuring that your vehicle software is updated can help mitigate this problem.
