What vehicles are most commonly affected by C06FB?

Commonly affected vehicles include the 2015-2020 Ford Explorer, along with other Ford models that utilize similar chassis control systems. Check for any recalls or Technical Service Bulletins (TSBs) related to your model.

How can I prevent C06FB from happening again?

To avoid recurring C06FB issues, ensure regular vehicle maintenance, check wiring and connectors during inspections, and promptly address any electronic system warnings that may arise.

What is C06FB?

The diagnostic trouble code (DTC) C06FB indicates a malfunction in the chassis control module, particularly related to the electronic stability control (ESC) system. This code is commonly found in vehicles like the 2015-2020 Ford Explorer, where the ESC plays a crucial role in maintaining vehicle stability during various driving conditions. When C06FB is triggered, it usually means that the module has detected an abnormality in its communication with other control units or a fault within the ESC system itself. Drivers may notice issues such as the traction control light illuminating on the dashboard or a reduced ability to maintain traction on slippery surfaces. This could lead to compromised vehicle handling and increased risk during adverse conditions, making it essential to address promptly. Left unchecked, a malfunctioning chassis control module can lead to further complications, including a complete failure of the ESC system. Therefore, understanding this code is vital for ensuring both safety and performance in affected vehicles.

System: C - Chassis (ABS, Steering, Suspension)

Symptoms

Common symptoms when C06FB is present:

  • The check engine light or traction control light illuminates and stays on, indicating a fault in the stability control system.
  • Drivers may experience erratic vehicle handling, especially during acceleration or when navigating turns, creating an unsettling driving experience.
  • Fuel economy may decrease by 10-20% due to the engine compensating for stability control issues, leading to increased fuel consumption.
  • The vehicle may exhibit unintended acceleration or deceleration, making it difficult to maintain consistent speed.
  • In some cases, the vehicle may enter limp mode, restricting power to prevent further damage until the issue is resolved.

Possible Causes

Most common causes of C06FB (ordered by frequency):

  1. 1. Faulty chassis control module (70% likelihood) - The module may fail due to electrical issues or internal faults, leading to communication errors.
  2. 2. Damaged wiring or connectors (15% likelihood) - Corrosion or physical damage to the wiring harness can disrupt signals between the module and other components, triggering the C06FB code.
  3. 3. Faulty wheel speed sensors (10% likelihood) - These sensors provide crucial data to the chassis control module for stability control; if they malfunction, it can cause erroneous readings.
  4. 4. Low battery voltage (3% likelihood) - Insufficient power supply can affect module performance, leading to erroneous codes.
  5. 5. Rarely, software issues in the vehicle's ECU (2% likelihood) - Occasionally, a software glitch may cause the module to misinterpret sensor data, generating a false C06FB code.
