What vehicles are most commonly affected by C0860?

C0860 is commonly found in 2015-2018 Chevrolet Silverado models, as well as some GMC Sierra and Cadillac vehicles. Check for any recalls or technical service bulletins related to stability control.

How can I prevent C0860 from happening again?

Regular maintenance checks on your vehicle's electrical systems and stability control components can help. Keeping an eye on warning lights and addressing issues promptly also aids in prevention.

What is C0860?

DTC C0860 is a diagnostic trouble code indicating a problem with the vehicle's stability control system. This code is commonly triggered when the system detects an issue with the communication between the Electronic Stability Control (ESC) module and other onboard systems. The ESC is crucial for maintaining vehicle stability during challenging driving conditions, such as slippery roads or sudden maneuvers. When C0860 is logged, it typically means that the vehicle's ability to control traction and stability is compromised, which can lead to hazardous driving situations. In practical terms, you might notice that the traction control or stability control warning lights are illuminated on your dashboard, indicating that the system has been disabled. Ignoring this code can result in poor handling, especially in adverse weather conditions, increasing the risk of accidents. Therefore, addressing C0860 promptly is essential to ensure both safety and vehicle performance. It's important to have a professional technician perform a thorough diagnostic to pinpoint the exact cause of the code and recommend the appropriate repairs.

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

Symptoms

Common symptoms when C0860 is present:

  • The traction control light stays illuminated on the dashboard, indicating a malfunction in the system.
  • You may experience reduced vehicle stability during acceleration or sharp turns, leading to a feeling of loss of control.
  • Fuel economy may decrease due to the vehicle's stability system trying to compensate for traction loss, resulting in more frequent engine power adjustments.
  • Unusual noises might occur when the stability control system attempts to engage, such as clicking or grinding sounds.
  • The vehicle may exhibit erratic behavior, such as oversteering or understeering during routine driving conditions.

Possible Causes

Most common causes of C0860 (ordered by frequency):

  1. The most common cause of C0860 is a faulty ESC module, with an estimated likelihood of about 40%. This can result from electrical failures or software issues.
  2. Another frequent cause is damaged or corroded wiring in the stability control system, which can disrupt communication. This accounts for roughly 30% of C0860 cases.
  3. Worn or defective wheel speed sensors can trigger this code, as they play a vital role in stability control. Regular inspections can help prevent this issue.
  4. Less commonly, issues with the Anti-lock Braking System (ABS) can interfere with stability control functionality, leading to C0860. This is a more serious concern that may require extensive repairs.
  5. A rare but possible cause is software malfunctions within the vehicle’s ECU, which can sometimes be resolved with a simple update.
