Can I drive my car with C0585 or should I stop immediately?

It is advisable to stop driving as soon as possible. Ignoring the C0585 code can lead to compromised vehicle stability, which poses safety risks, especially in slippery conditions.

How can I diagnose C0585 myself using the GeekOBD APP?

To diagnose C0585, connect your GeekOBD APP to your vehicle's OBD2 port, scan for trouble codes, and note any additional codes or freeze frame data. This information helps in pinpointing the issue accurately.

What vehicles are most commonly affected by C0585?

The C0585 code is frequently seen in vehicles like the 2015-2020 Chevrolet Silverado, as well as other models from General Motors during that time frame. Checking for recalls or Technical Service Bulletins (TSBs) related to stability control systems in these models is advisable.

How can I prevent C0585 from happening again?

Regular maintenance, including checking your vehicle's wiring and connectors for signs of wear, can help prevent C0585. Keeping the stability control system software updated and promptly addressing any warning lights can also reduce the risk.

What is C0585?

The diagnostic trouble code (DTC) C0585 indicates a fault with the Stabilizer Control Module (SCM) within vehicles, particularly in models like the 2015-2020 Chevrolet Silverado. This code is triggered when the vehicle's computer detects a malfunction in the SCM, which is responsible for managing the vehicle’s stability control system. The stability control system helps maintain traction and control, especially during adverse driving conditions. When this code appears, it may lead to diminished handling performance, increased stopping distances, or even a loss of traction in slippery conditions. Owners might notice the check engine light illuminating on their dashboard or experience erratic handling characteristics. Ignoring this code could lead to more severe stability-related issues, potentially compromising vehicle safety. Moreover, this code can also affect other systems in the vehicle, such as anti-lock brakes and traction control, making it a critical issue to address promptly. To resolve the C0585 code, proper diagnostic procedures must be followed, which often require specialized tools like the GeekOBD APP to read the trouble codes and perform system checks effectively.

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

Symptoms

Common symptoms when C0585 is present:

  • The check engine light is illuminated, indicating a fault with the stability control system.
  • Drivers may feel a loss of traction or poor handling, especially during turns or on wet surfaces.
  • The vehicle may exhibit unusual braking behavior, with the brakes applying unexpectedly or not releasing properly.
  • Dashboard alerts for stability control or traction control may appear, providing additional warnings.
  • Reduced fuel economy may be noticeable, as the vehicle compensates for the malfunctioning stability control system.

Possible Causes

Most common causes of C0585 (ordered by frequency):

  1. The most common cause of the C0585 code is a faulty Stabilizer Control Module, which has a likelihood of about 60%. This can happen due to wear and tear or exposure to moisture.
  2. Another cause could be damaged wiring or connectors leading to the SCM, which can disrupt communication and function. This is seen in approximately 25% of cases.
  3. Faulty wheel speed sensors can also trigger this code, as they provide crucial data for the stability control system. Regular checks can help prevent such issues.
  4. Less commonly, a software issue in the vehicle's ECU could cause the C0585 code, which can often be resolved by reprogramming or updating the software.
  5. In rare cases, a malfunction in the brake system can falsely trigger the C0585 code, making it essential to check for related trouble codes.
