While you may be able to drive your vehicle, doing so can be dangerous due to potential loss of steering assist. It's best to address the C058D code immediately to ensure safe driving conditions.
How can I diagnose C058D myself using GeekOBD APP?
Using the GeekOBD APP, you can scan for the C058D code and view freeze frame data. This will help you understand the conditions under which the fault occurred. You can also use the app to check other related codes that may provide additional insight.
What vehicles are most commonly affected by C058D?
The C058D code is commonly found in 2015-2018 models of Chevrolet Silverado and GMC Sierra. If you own one of these vehicles, be vigilant about any steering issues and have them checked regularly.
How can I prevent C058D from happening again?
Regular maintenance of your vehicle's steering system, including visual inspections and timely repairs of any wiring damage, can help prevent the recurrence of the C058D code. Additionally, keeping the steering system clean and free from corrosion will also contribute to its longevity.
What is C058D?
The diagnostic trouble code (DTC) C058D indicates a problem with the steering system, specifically related to the steering assist motor circuit. This code typically appears in vehicles equipped with an electronic power steering system, such as the 2015-2018 Chevrolet Silverado and GMC Sierra. When the C058D code is triggered, it suggests that the power steering control module has detected an abnormal condition in the steering assist function. This could result from various issues, including communication problems between the module and the steering motor, an open or shorted wiring harness, or even a malfunctioning steering assist motor. If not addressed promptly, this issue can lead to a loss of power steering assistance, making it difficult to steer the vehicle, especially at lower speeds. Drivers may experience increased effort while turning the steering wheel, which can be particularly dangerous in tight situations or during parking maneuvers. Ignoring this code could result in further damage to the steering system, increased repair costs, and compromise vehicle safety.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C058D is present:
- The check engine light illuminates on the dashboard, indicating a fault detected by the vehicle's onboard diagnostics.
- Steering feels heavy or unresponsive, especially at low speeds, making it difficult to maneuver the vehicle in tight spaces.
- Intermittent loss of power steering assist occurs, where the steering may function normally at times but then becomes excessively stiff or unresponsive.
- Unusual noises from the steering column or motor, such as grinding or whining sounds while turning the wheel.
- Abnormal behavior of the vehicle's traction control or stability systems, which may engage unexpectedly due to the steering fault.
Possible Causes
Most common causes of C058D (ordered by frequency):
- The most common cause of the C058D code is a faulty steering assist motor, which accounts for about 40% of cases. When this motor fails, it can disrupt the power steering assistance, leading to difficulty steering.
- Another possible cause is a damaged wiring harness or connector issues, which can occur from wear and tear, or exposure to the elements. This is often seen in vehicles with high mileage, contributing to around 30% of reported cases.
- Corrosion or poor connections at the steering system control module can lead to communication failures, making up roughly 20% of cases. Regular inspections can help prevent this issue.
- Less commonly, a software glitch in the steering control module may cause the C058D code to trigger, especially after a recent update or repair.
- In rare instances, physical damage to the steering rack or column could also lead to this code, typically after an accident or collision.
