What is C01AE?

The diagnostic trouble code C01AE indicates a malfunction in the brake control module of your vehicle. This code is particularly prevalent in models such as the 2015-2018 Ford F-150, but can also affect various other Ford vehicles. The brake control module (BCM) is crucial for managing brake functions, including anti-lock braking system (ABS) operations, electronic stability control (ESC), and traction control. When the BCM fails or exhibits errors, it can lead to significant safety issues, including compromised braking performance. Symptoms may include the illumination of the 'Check Engine' light, malfunctioning ABS, or traction control warnings. If not addressed promptly, this malfunction can result in reduced vehicle safety, increased stopping distances, and potential brake failure in critical situations. Given the importance of the brake system, it is essential to diagnose and rectify any issues related to the C01AE code as soon as possible, ensuring that your vehicle remains safe to drive and compliant with vehicle regulations.

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

Symptoms

Common symptoms when C01AE is present:

  • The 'Check Engine' light remains illuminated, indicating a fault related to the brake control module.
  • You may experience erratic ABS activation, especially during hard braking, which can cause the brakes to pulse unexpectedly.
  • Drivers might notice a decrease in traction control effectiveness, leading to wheel slip during acceleration on wet or slippery surfaces.
  • There may be unusual noises from the braking system, such as grinding or squeaking, which could indicate underlying issues with the brake components.
  • In some cases, the brake pedal may feel spongy or unresponsive, which can be alarming and indicates a serious issue.

Possible Causes

Most common causes of C01AE (ordered by frequency):

  1. The most common cause of C01AE is a failed brake control module, which can occur in approximately 60% of cases due to electrical failures or internal component malfunctions.
  2. Another cause could be wiring issues, such as frayed or corroded wires that prevent proper communication between the BCM and other systems, accounting for about 25% of issues.
  3. Poor connections at the BCM or related sensors can lead to intermittent faults, which are often overlooked; this accounts for about 10% of the problems.
  4. Less commonly, software issues or firmware bugs within the BCM can cause this code to trigger, which may require a software update as part of the fix.
  5. Rarely, external factors like water intrusion or impact damage from an accident can affect the BCM's functionality.
