What is C0957?

The diagnostic trouble code (DTC) C0957 indicates a traction control system malfunction. This code is prevalent in various vehicles, particularly in models like the 2013-2018 Chevrolet Silverado and the 2014-2019 GMC Sierra. The traction control system is designed to prevent wheel spin during acceleration by applying brakes to specific wheels or reducing engine power. When the C0957 code is triggered, it typically signifies that the traction control module has detected a fault in the system, which may prevent the system from functioning properly. This malfunction can lead to reduced vehicle stability, especially in slippery conditions, making it crucial for drivers to address this issue promptly. Ignoring this code could lead to increased tire wear, diminished fuel efficiency, and compromised safety due to the vehicle's inability to maintain traction. If you encounter this code, it’s essential to have your vehicle diagnosed by a qualified technician who can accurately identify the underlying issues and recommend appropriate repairs.

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

Symptoms

Common symptoms when C0957 is present:

  • The traction control light illuminates on the dashboard, indicating potential system issues.
  • Drivers may notice reduced acceleration or difficulty maintaining traction, especially on wet or icy roads.
  • Increased fuel consumption may be observed due to the traction control system attempting to compensate for wheel slip.
  • The vehicle may exhibit erratic behavior during acceleration, with the engine hesitating or stalling unexpectedly.
  • A noticeable decrease in overall vehicle stability and handling may occur when navigating turns or uneven surfaces.

Possible Causes

Most common causes of C0957 (ordered by frequency):

  1. The most common cause of the C0957 code is a faulty traction control module, which accounts for approximately 60% of cases. This can be due to electrical malfunctions or internal component failures.
  2. Another frequent issue is damaged or corroded wiring harnesses connected to the traction control system, which can lead to signal loss. This problem is often seen in vehicles exposed to harsh weather conditions.
  3. Faulty wheel speed sensors can also trigger this code, as they provide essential data to the traction control system. Regular inspections can help prevent this issue.
  4. Less common but serious causes include a malfunctioning ABS system, which can impact the overall functionality of the traction control system.
  5. In rare cases, software glitches in the vehicle's onboard computer can also result in a C0957 code, often requiring a software update or reset.
