What vehicles are most commonly affected by C0595?

DTC C0595 is frequently observed in various models from General Motors, particularly the Chevrolet Silverado (2007-2013) and GMC Sierra (2007-2013). These vehicles may have known issues related to the traction control system.

How can I prevent C0595 from happening again?

Regular maintenance, including electrical system checks and software updates, can help prevent issues with the traction control module. Additionally, ensure that any previous repairs are done correctly to maintain system integrity.

What is C0595?

The Diagnostic Trouble Code (DTC) C0595 is associated with the vehicle's traction control system, particularly in General Motors vehicles such as Chevrolet and GMC models. This code indicates a malfunction within the Traction Control Module (TCM), which is responsible for regulating wheel slip during acceleration. When this code is triggered, it usually means that the TCM has detected a fault in either the communication with the Anti-lock Braking System (ABS) or the electronic stability control system. In practical terms, if your vehicle is equipped with traction control, you may experience a warning light on the dashboard, and the system may become inactive. This is critical because traction control helps prevent wheel spin, especially in slippery conditions, enhancing driver safety and vehicle stability. Ignoring this code can lead to reduced vehicle control during acceleration, particularly on wet or icy roads, increasing the risk of accidents. Therefore, it's vital to address this issue promptly to ensure your vehicle operates safely and efficiently.

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

Symptoms

Common symptoms when C0595 is present:

  • The traction control warning light illuminates on the dashboard, indicating a system fault.
  • You may notice a decrease in vehicle stability during acceleration, especially in wet conditions.
  • The vehicle may experience unexpected wheel slip, leading to loss of traction when starting from a stop.
  • The ABS warning light may also appear, indicating related system issues.
  • In some cases, there could be an overall decrease in fuel efficiency due to improper traction control operation.

Possible Causes

Most common causes of C0595 (ordered by frequency):

  1. The most common cause is a faulty Traction Control Module, which has a likelihood of around 60%. This can occur due to electrical issues or internal failures within the module.
  2. A second potential cause is damaged wiring or connectors related to the TCM, which can disrupt proper communication, accounting for about 25% of cases.
  3. A third cause could be a malfunctioning ABS sensor, which is crucial for the TCM's operation. Regular inspections can help prevent this issue.
  4. Less common causes include software glitches within the vehicle's control systems, which may require a software update.
  5. A rare but possible cause is a failure within the Electronic Control Unit (ECU), which manages multiple vehicle systems, including traction control.
