What is B07E7?

The Diagnostic Trouble Code (DTC) B07E7 indicates a problem with the vehicle's integrated trailer brake control module. This code is particularly common in 2015-2019 Ford F-150 trucks, but it can also appear in other models equipped with similar braking systems. When this code is triggered, it often means that the trailer brake controller is experiencing a malfunction, which can affect towing performance and safety. If you see this code, you might notice that the trailer brakes are not engaging correctly, leading to uneven braking or extended stopping distances when towing. In practical terms, this could mean serious safety issues while driving, especially if you're carrying heavy loads. Ignoring this code could lead to further damage to the braking system, increased repair costs, or even a potential accident. It’s crucial to address the underlying issues promptly to ensure safe operation of your vehicle, especially if you frequently tow trailers or heavy loads.

Symptoms

Common symptoms when B07E7 is present:

  • The check engine light remains illuminated, indicating a fault that requires attention.
  • Inconsistent trailer braking performance may lead to swaying or difficulty in stopping when towing.
  • You may experience increased stopping distances when attempting to brake while towing a trailer.
  • The trailer brake controller may fail to respond, leaving the trailer brakes inactive.
  • Unusual sounds or smells from the braking system could indicate overheating or wear.

Possible Causes

Most common causes of B07E7 (ordered by frequency):

  1. The most common cause of the B07E7 code is a faulty trailer brake control module, with a likelihood of about 60%. This module can fail due to electrical issues or internal component wear.
  2. Another frequent cause is damaged wiring or connectors in the trailer brake system, which can disrupt communication between the vehicle and the trailer brakes.
  3. Corrosion on the electrical connections can prevent proper current flow, leading to intermittent issues and triggering the code. Regular inspections can help prevent this.
  4. Less commonly, a failed brake actuator can lead to a loss of trailer braking function, which can be serious if not addressed.
  5. Rarely, a software issue within the vehicle's computer may also trigger the B07E7 code, requiring a software update or reprogramming.
