What is C068E?

The C068E diagnostic trouble code (DTC) is primarily associated with the Electronic Stability Control (ESC) and is often found in various Chevrolet and GMC models manufactured between 2015 and 2020. This code indicates a malfunction in the vehicle's ESC system, which is designed to enhance vehicle stability by detecting and reducing loss of traction. When the C068E code is triggered, it typically reflects issues related to the stability control module, wheel speed sensors, or the vehicle’s communication network. For car owners, this means that the vehicle's traction control may not function properly, which can lead to a higher risk of skidding or losing control, especially in slippery conditions. Common symptoms of this code may include the illumination of the check engine light, a flashing stability control warning light, or even noticeable changes in handling when cornering. Ignoring the C068E code can lead to further complications, as it may impact the vehicle's overall safety features and performance. Therefore, addressing this code promptly is crucial for maintaining safe driving conditions.

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

Symptoms

Common symptoms when C068E is present:

  • Check engine light illuminates continuously, indicating potential issues with the ESC system.
  • Stability control warning light may flash intermittently during driving, suggesting traction loss.
  • Vehicle may exhibit unusual handling characteristics, such as skidding or oversteering, especially in wet conditions.
  • Unresponsive traction control system that fails to engage during slippery conditions, compromising safety.
  • Increased stopping distance noted by the driver, raising concerns about overall braking effectiveness.

Possible Causes

Most common causes of C068E (ordered by frequency):

  1. The most common cause of the C068E code is a faulty wheel speed sensor, which accounts for approximately 60% of cases. These sensors monitor the rotation speed of each wheel to help manage stability control.
  2. Another prevalent cause is a malfunctioning stability control module, which may arise from software glitches or hardware failures. This can disrupt communication within the ESC system.
  3. Poor electrical connections or damaged wiring in the ESC circuit can lead to intermittent faults, so regular inspections can prevent these issues from developing.
  4. Less common but serious causes include issues with the vehicle's ABS (Anti-lock Braking System), which can affect how the ESC system operates.
  5. A rare but possible cause is malfunctioning software within the vehicle’s control modules, requiring updates or reprogramming to resolve.
