Common Questions

What does C071F mean and how does it affect my car?

The C071F code indicates a malfunction in the electronic parking brake system, which can compromise the safety of your vehicle by failing to hold it securely in place. This can result in unintended movement, particularly on inclines, and may lead to increased repair costs if not addressed promptly.

What are the most common causes of C071F and how much does it cost to fix?

Common causes of C071F include a faulty parking brake actuator, which is the most frequent issue, accounting for about 60% of cases. Repair costs for actuator replacement typically range from $200 to $400. Other causes may include wiring issues and software glitches, with varying repair costs depending on the specific problem.

Can I drive my car with C071F or should I stop immediately?

Driving a vehicle with the C071F code is not recommended, as it poses a safety risk. The electronic parking brake may not function correctly, leading to potential accidents. It's best to address this issue immediately to ensure safe vehicle operation.

How can I diagnose C071F myself using GeekOBD APP?

To diagnose C071F with the GeekOBD APP, start by connecting the app to your vehicle's OBD2 port. Run a full scan to retrieve the C071F code along with any other codes that may be present. Review freeze frame data to understand the conditions under which the fault occurred and follow the diagnostic steps outlined in the app.

What vehicles are most commonly affected by C071F?

C071F is most commonly reported in Ford vehicles, particularly models from 2015 to 2020, including the Ford Focus, Fusion, and Escape. It's important to check for any recalls or technical service bulletins related to the EPB system for these models.

How can I prevent C071F from happening again?

To prevent C071F from recurring, ensure regular maintenance of your vehicle's brake system, including checking brake fluid levels and inspecting wiring for damage. Additionally, keep the software updated to avoid glitches, and avoid using the parking brake excessively in harsh conditions.

What is C071F?

The diagnostic trouble code (DTC) C071F is associated with the Electronic Parking Brake (EPB) system in various Ford vehicles, specifically models ranging from 2015 to 2020. This code indicates a malfunction within the EPB module or its associated components, which are crucial for the safe and effective operation of the parking brake. When this code is triggered, it typically means that the system has detected an issue with the EPB's ability to engage or disengage properly, which could lead to significant safety concerns. In practical terms, if the parking brake isn't functioning correctly, it may not hold the vehicle securely on an incline, increasing the risk of unintentional movement. Moreover, drivers may experience symptoms such as a warning light on the dashboard, difficulty engaging the parking brake, or unusual noises when attempting to activate the brake. Addressing this issue promptly is essential—not only to ensure safe vehicle operation but also to prevent further damage to the EPB system, which can lead to more costly repairs down the line. Additionally, neglecting to resolve the C071F code may result in failed vehicle inspections, especially in regions that require thorough checks on braking systems. Therefore, understanding the implications of this code and seeking timely repairs is crucial for vehicle safety and reliability.

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

Symptoms

Common symptoms when C071F is present:

  • The parking brake warning light illuminates on the dashboard, indicating a potential issue with the system.
  • You may notice that the electronic parking brake does not engage or disengage as expected, which can cause safety concerns.
  • Unusual grinding or clicking noises may occur when attempting to use the parking brake, suggesting mechanical issues.
  • Increased resistance when pulling the parking brake lever could indicate a malfunctioning actuator or wiring issue.
  • The vehicle may exhibit unintended rolling on an incline if the parking brake fails to hold securely.

Possible Causes

Most common causes of C071F (ordered by frequency):

  1. The most common cause of the C071F code is a malfunctioning electronic parking brake actuator, which accounts for approximately 60% of cases. This can occur due to wear and tear or electrical issues.
  2. A faulty wiring harness or corroded connectors can also trigger this code, especially in regions with harsh weather; this is seen in about 25% of cases.
  3. Low brake fluid levels might be a contributing factor, as the EPB system can fail if the hydraulic system is compromised.
  4. In rare instances, a software glitch within the vehicle's control module could lead to this code being set, necessitating a software update.
  5. Less common, but serious, is the potential for a mechanical failure within the brake assembly, which could compromise the entire parking brake system.
