What is C0F96?

The diagnostic trouble code (DTC) C0F96 indicates an issue related to the vehicle's communication with its various electronic control units (ECUs). This code is particularly prevalent in 2015-2019 Ford F-150 models but can also appear in other Ford vehicles. Essentially, C0F96 suggests that there's a problem with the electric parking brake system or its related components, often indicating a malfunction in the parking brake control module or a communication error between the module and the vehicle's main computer system. As a car owner, understanding this code is crucial because it can lead to issues with the vehicle's ability to engage or disengage the parking brake, which can be dangerous, especially on inclines. Drivers may experience symptoms such as a persistent warning light on the dashboard or irregularities in the vehicle's braking performance. Ignoring this code can lead to further complications, including complete failure of the parking brake system, which may result in costly repairs down the line.

Symptoms

Common symptoms when C0F96 is present:

  • Check engine light remains illuminated, indicating a persistent issue.
  • Electric parking brake fails to engage or disengage properly, affecting vehicle safety.
  • Unusual noises coming from the parking brake module when engaged.
  • Dashboard warning messages related to the parking brake system.
  • Increased braking distance noted during vehicle operation, potentially leading to safety concerns.

Possible Causes

Most common causes of C0F96 (ordered by frequency):

  1. The most common cause is a faulty parking brake control module, which occurs in about 60% of cases. This module may fail due to electrical issues or water intrusion.
  2. Another frequent cause is damaged wiring or connectors related to the parking brake system. Corrosion or wear can lead to poor communication with the ECU.
  3. A third cause could be a software issue within the vehicle's computer systems. Regular software updates can help prevent these problems.
  4. Less common but serious is a failure in the vehicle's main ECU, which can lead to multiple DTCs being triggered and may require extensive diagnostic work.
  5. Rarely, a mechanical failure in the parking brake itself, such as a broken cable or actuator, can also trigger the C0F96 code.
