What is C0599?

The diagnostic trouble code (DTC) C0599 indicates a malfunction in the stability control system of your vehicle. This code is primarily associated with various models of Chevrolet, particularly the Silverado produced between 2013 and 2020, but can also affect other makes and models with similar electronic stability control systems. When this code is triggered, it usually points to an issue with the communication between the electronic control unit (ECU) and other components of the stability system. The stability control system is crucial for maintaining vehicle stability during dynamic driving situations, such as sharp turns or slippery conditions. A malfunction can lead to erratic handling, decreased traction, and a potential increase in the risk of losing control of the vehicle. Common symptoms include the activation of the traction control warning light and the check engine light, as well as unresponsive or erratic stability control functionality. It’s important to address this issue promptly to ensure safety while driving, as ignoring it could lead to more significant problems down the line.

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

Symptoms

Common symptoms when C0599 is present:

  • The check engine light stays on constantly, indicating a persistent issue with the stability control system.
  • Traction control light may illuminate, which can affect your vehicle's handling in adverse weather conditions.
  • The vehicle may exhibit erratic handling, especially during turns or wet conditions, leading to potential safety risks.
  • Loss of stability control functionality, meaning the system may not engage when needed, which can be dangerous.
  • A noticeable decrease in fuel efficiency, possibly due to the stability control system working harder to compensate for the malfunction.

Possible Causes

Most common causes of C0599 (ordered by frequency):

  1. The most common cause of code C0599 is a faulty wheel speed sensor, occurring in about 60% of cases. This sensor monitors the speed of each wheel and sends data to the ECU to maintain stability control.
  2. Another potential cause could be damaged wiring or poor connections within the stability control system. Corrosion or wear can disrupt the signals sent between components.
  3. A third cause might be a malfunctioning ECU, which is less common but can occur due to software issues or electrical failures. Regular maintenance can help prevent these failures.
  4. Less common, but serious, is the possibility of a failure within the stability control module itself, which can require replacement and may lead to high repair costs.
  5. A rare but possible cause is interference from aftermarket modifications, such as suspension upgrades or tire changes that aren’t compatible with the stability control system.
