What is C0A06?

The DTC C0A06 is a diagnostic trouble code that indicates a malfunction in the electric parking brake system, specifically related to the parking brake actuator. This code is commonly seen in vehicles like the 2015-2020 Ford F-150 and Ford Explorer. When this code is triggered, it usually denotes that the parking brake isn’t functioning correctly, which can pose safety risks while driving. The electric parking brake system is designed to automatically engage and release, allowing drivers to secure their vehicles safely. If the system detects an issue, such as a fault in the actuator or wiring, it can result in symptoms like the parking brake warning light illuminating on the dashboard. Ignoring this code can lead to further complications, such as a complete failure of the parking brake system, making it critical to address promptly. In addition to safety concerns, a malfunctioning parking brake can lead to costly repairs if not diagnosed early. Understanding this code and its implications is vital for maintaining your vehicle’s safety and functionality.

Symptoms

Common symptoms when C0A06 is present:

  • The parking brake warning light remains illuminated on the dashboard, indicating a malfunction.
  • Drivers may experience difficulty in engaging or disengaging the parking brake, which can lead to safety hazards.
  • Unusual noises such as grinding or clicking when attempting to activate the parking brake may occur, pointing to mechanical issues.
  • The vehicle may roll when parked, suggesting that the parking brake is not functioning as intended.
  • Increased stopping distances can be observed if the parking brake does not engage properly.

Possible Causes

Most common causes of C0A06 (ordered by frequency):

  1. The most common cause is a faulty parking brake actuator, which has a likelihood of about 60%. This can happen due to wear and tear over time.
  2. Another potential cause is damaged wiring or connections within the parking brake system, which could be due to corrosion or physical damage.
  3. A third cause is low voltage or battery issues, which can prevent the actuator from receiving the necessary power to function correctly. Regular battery maintenance can help prevent this.
  4. Less common but serious causes include a malfunctioning Electronic Control Unit (ECU) that manages the parking brake system.
  5. A rare cause could be a software issue within the vehicle's onboard systems, which may require a software update from a dealership.
