Common Questions

What does C0AD6 mean and how does it affect my car?

DTC C0AD6 indicates a fault in your vehicle's Electric Power Steering system. This can lead to increased steering effort, especially at low speeds, making it difficult to maneuver your vehicle. If you ignore this code, you may face serious steering issues down the line, affecting overall vehicle safety.

What are the most common causes of C0AD6 and how much does it cost to fix?

The most common causes for C0AD6 include a faulty power steering control module, damaged wiring, or low power steering fluid levels. Repair costs can range from $150 for wiring repairs to over $800 for module replacement, depending on the issue.

Can I drive my car with C0AD6 or should I stop immediately?

While you can drive your vehicle with C0AD6, it is not advisable due to the risk of losing power steering assist. This can make steering difficult and potentially dangerous. It's best to have the issue diagnosed and repaired as soon as possible.

How can I diagnose C0AD6 myself using GeekOBD APP?

Using the GeekOBD APP, you can scan your vehicle's OBD2 system to retrieve DTC codes, including C0AD6. The app provides freeze frame data to help you understand when the fault occurred, allowing you to narrow down potential causes for further investigation.

What vehicles are most commonly affected by C0AD6?

DTC C0AD6 is frequently seen in models like the 2015-2018 Ford F-150 and similar vehicles equipped with Electric Power Steering technology. Always check for any recalls or Technical Service Bulletins (TSBs) related to your vehicle.

How can I prevent C0AD6 from happening again?

To prevent DTC C0AD6 from recurring, regularly inspect your vehicle's power steering system for any signs of wear and tear, ensure proper fluid levels, and keep wiring connections clean and intact. Additionally, maintain regular software updates for your vehicle's onboard computer.

What is C0AD6?

The diagnostic trouble code (DTC) C0AD6 indicates a problem with the vehicle's Electric Power Steering (EPS) system. This code is primarily seen in various models, including the 2015-2018 Ford F-150, but can also affect other vehicles equipped with EPS technology. When this code is triggered, it generally signifies that the system has detected an issue that could prevent the steering from functioning correctly, potentially leading to a loss of power steering assistance. This can result in a heavier steering feel, making the vehicle harder to maneuver, especially at low speeds. If left unresolved, it may lead to more severe steering system failures, which can compromise vehicle safety. Car owners may notice symptoms like the check engine light illuminating, or they may experience unusual steering resistance or noise while turning. Ignoring this code can lead to further damage and costly repairs down the line. Therefore, it is crucial to address DTC C0AD6 promptly to ensure safe and reliable vehicle operation.

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

Symptoms

Common symptoms when C0AD6 is present:

  • Check engine light remains illuminated, indicating a fault in the steering system.
  • Steering wheel feels heavier than usual, particularly when making turns or maneuvering at low speeds.
  • Unusual noises such as grinding or whining may occur while steering.
  • Increased difficulty in steering, which can become dangerous in tight situations.
  • Intermittent loss of power steering assist, leading to inconsistent steering feel.

Possible Causes

Most common causes of C0AD6 (ordered by frequency):

  1. The most common cause is a faulty power steering control module, which has a likelihood of about 60%. This module regulates the EPS system's performance.
  2. A second potential cause is damaged wiring or connections within the EPS system, which can lead to shorts or open circuits, impacting system functionality.
  3. Thirdly, low power steering fluid levels can also trigger this code, although it's less common in EPS systems due to their design. Regular checks can help prevent this issue.
  4. Less commonly, a failing EPS motor can be the culprit. This can be serious, as replacing the motor is often more expensive.
  5. A rare but possible cause includes software glitches in the vehicle's onboard computer system. Updating the vehicle’s software may resolve this issue.
