What vehicles are most commonly affected by C07FB?

C07FB is commonly seen in 2015-2018 Ford Explorer and Fusion models. These vehicles may experience issues related to their Adaptive Cruise Control systems, particularly if they haven't had recent software updates.

How can I prevent C07FB from happening again?

Regular maintenance, including periodic checks of wiring and sensors connected to the ACC system, can help. Ensuring that your vehicle's software is up-to-date can also prevent potential issues.

What is C07FB?

The diagnostic trouble code (DTC) C07FB indicates an issue related to the vehicle's communication system, particularly in the context of the Adaptive Cruise Control (ACC) module in certain Ford models, including the Explorer and Fusion from 2015 to 2018. This code signifies that there is a malfunction occurring within the ACC system, which is responsible for maintaining a set speed and distance from the vehicle ahead. When this code is triggered, it may affect how well the ACC operates, potentially leading to an unsafe driving experience. Drivers might notice that their ACC does not engage, disengages unexpectedly, or may even affect other electronic systems in the vehicle. Ignoring this code can lead to further complications, including increased wear on the braking system due to erratic operation. It’s crucial to have this issue addressed promptly to ensure your vehicle remains safe and functional. Addressing DTC C07FB not only improves safety but also restores full functionality to systems designed to enhance your driving experience.

Symptoms

Common symptoms when C07FB is present:

  • Check engine light stays on constantly, indicating a persistent issue with the ACC system.
  • The Adaptive Cruise Control fails to engage or disengages unexpectedly, making highway driving less convenient and potentially hazardous.
  • You may experience erratic braking behavior, where the vehicle applies brakes unexpectedly, leading to discomfort and safety concerns.
  • Increased fuel consumption, as the vehicle may not be able to maintain optimal speed settings effectively.
  • Inability to use cruise control features, which can lead to fatigue on long drives.

Possible Causes

Most common causes of C07FB (ordered by frequency):

  1. Faulty ACC module - This is the most common cause, with a likelihood of about 60%. The module might be damaged due to electrical issues or moisture entry.
  2. Wiring issues - Loose connections or damaged wiring can result in communication failures between the ACC and the vehicle's computer system, occurring in about 25% of cases.
  3. Sensor malfunctions - Sensors that relay distance information may fail, contributing to about 10% of cases. Regular checks and cleaning can help prevent this.
  4. Software glitches - Rarely, outdated software can cause issues, especially in vehicles that have not received necessary updates.
  5. Mechanical failures - Less common but serious, mechanical failure in components that support the ACC can cause significant issues.
