How can I diagnose C0C6D myself using GeekOBD APP?

Using the GeekOBD APP, connect to your vehicle's OBD2 port, scan for codes, and review the freeze frame data to understand the circumstances under which the C0C6D code was triggered. This will help you identify potential issues.

What vehicles are most commonly affected by C0C6D?

The C0C6D code is frequently found in models like the 2016-2020 Chevrolet Equinox and GMC Terrain, particularly if they've experienced steering issues or electrical faults.

How can I prevent C0C6D from happening again?

Regular maintenance, including checking the power steering system and ensuring proper alignment, can help prevent the C0C6D code from reoccurring. Also, avoid harsh driving conditions that could stress the steering components.

What is C0C6D?

The C0C6D diagnostic trouble code (DTC) is a manufacturer-specific code that indicates an issue with the vehicle's power steering system, specifically related to the steering angle sensor. When this code is triggered, it means that the vehicle's onboard computer has detected an inconsistency or malfunction in the sensor's data. This can lead to various issues, including difficulty steering, an unresponsive steering wheel, or the steering assist feature being disabled. Drivers may experience a sudden loss of power steering, making it more challenging to maneuver the vehicle, especially at low speeds or during parking maneuvers. The power steering system relies on electric motors and sensors to provide the necessary assistance, and when the steering angle sensor fails, it can affect the overall steering control. In practical terms, if you're driving a 2017 Chevrolet Equinox and see the check engine light illuminated along with a message alerting you to the power steering issue, it's crucial to address it immediately. Ignoring the C0C6D code can lead to more severe steering problems, increased repair costs, and potential safety hazards on the road.

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

Symptoms

Common symptoms when C0C6D is present:

  • The check engine light remains illuminated, indicating a fault in the power steering system.
  • Drivers may notice difficulty in steering, especially when trying to turn at low speeds or during parking.
  • Increased steering effort is required, leading to noticeable fatigue during long drives.
  • The steering assist feature may deactivate, resulting in a very stiff steering wheel.
  • Unusual noises may occur from the steering column when turning, indicating mechanical failure.

Possible Causes

Most common causes of C0C6D (ordered by frequency):

  1. The most common cause of the C0C6D code is a faulty steering angle sensor, with a likelihood of about 70%. This sensor measures the angle of the steering wheel and sends data to the vehicle’s computer for proper steering assistance.
  2. Another potential cause could be damaged wiring or connectors leading to the steering angle sensor, which can result in intermittent signals and faults.
  3. Improper alignment or suspension issues can also trigger this code, as they affect the steering geometry and sensor readings.
  4. Less common causes include a malfunctioning power steering control module, which may require reprogramming or replacement.
  5. A rare but serious cause could be an internal failure within the power steering rack itself, necessitating a costly repair or replacement.
