Regular maintenance is key to preventing C025C. This includes inspecting wiring and connectors for corrosion, ensuring proper wheel alignment, and checking the condition of the wheel speed sensors during routine service.

What is C025C?

The diagnostic trouble code (DTC) C025C indicates a malfunction within the traction control system, particularly linked to the vehicle's wheel speed sensors or the traction control module itself. When this code appears, it typically signifies that the traction control module has detected a fault in the system, which can affect the vehicle's ability to maintain traction during slippery conditions. This can lead to issues such as reduced vehicle stability, especially in adverse weather conditions, making it crucial for drivers to address it promptly. In practical terms, if the traction control system is not functioning properly, it can compromise vehicle safety, particularly when accelerating on wet or icy roads. Drivers may notice that their vehicle behaves unpredictably, with the traction control light illuminated on the dashboard. Commonly seen in models like the Ford F-150 (2014-2018), Chevrolet Silverado (2014-2019), and GMC Sierra (2014-2019), this code can result from various underlying issues, including wiring problems, sensor failures, or module errors. Understanding the implications of DTC C025C is essential for maintaining vehicle safety and performance, making it a priority for car owners experiencing this diagnostic code.

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

Symptoms

Common symptoms when C025C is present:

  • The traction control light remains illuminated on the dashboard, indicating a persistent issue within the system.
  • The vehicle may experience reduced power during acceleration, leading to a struggle to gain speed, especially on slippery surfaces.
  • Drivers may notice an unusual amount of wheel slip or lack of traction control engagement in adverse weather conditions.
  • In some cases, the vehicle may exhibit erratic behavior, such as sudden braking or loss of power steering when the traction control system is activated.
  • There could also be a noticeable decrease in fuel efficiency as the vehicle attempts to compensate for excessive wheel slip.

Possible Causes

Most common causes of C025C (ordered by frequency):

  1. A faulty wheel speed sensor is the most common cause, accounting for approximately 45% of C025C occurrences. This sensor monitors the wheel rotation speed and relays information to the traction control module. If damaged or malfunctioning, it can lead to incorrect readings.
  2. Wiring issues, including damaged or corroded connections in the traction control system, represent about 30% of cases. These problems can disrupt communication between the sensors and the control module, leading to system failure.
  3. A malfunctioning traction control module itself can also trigger the C025C code, which happens in about 15% of instances. This may require a replacement or reprogramming of the module.
  4. Less common but serious causes include software glitches within the vehicle's computer that can lead to erroneous code readings, requiring a system update.
  5. Rarely, issues with the anti-lock brake system (ABS) can affect traction control, as both systems are interlinked. This might occur due to brake line leaks or faulty ABS components.
