What is C06C1?

The DTC code C06C1 indicates a communication issue within the vehicle's control module, specifically relating to the chassis control system. This code can arise in various makes and models, but it is frequently reported in vehicles like the 2016-2020 Chevrolet Silverado and 2017-2020 GMC Sierra. When the C06C1 code is triggered, it suggests that the chassis control module is unable to communicate effectively with other critical modules, which can lead to a range of operational problems. For instance, you might experience issues with the anti-lock braking system (ABS), traction control, or even stability control functions. In real-world terms, this can result in safety features not operating correctly, posing a risk to both the driver and passengers. The presence of this code often coincides with symptoms like warning lights on the dashboard, particularly for the ABS or traction control systems. Ignoring the C06C1 code could lead to more extensive damage and costly repairs, so addressing it promptly is crucial for maintaining vehicle safety and performance.

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

Symptoms

Common symptoms when C06C1 is present:

  • The check engine light or ABS warning light stays illuminated on the dashboard, indicating a fault in the chassis control system.
  • You may notice that the traction control system is unresponsive, especially during slippery conditions, leading to loss of vehicle stability.
  • Fuel efficiency may decline by 10-15% due to the engine's reduced performance caused by the communication error with the chassis control module.
  • The vehicle might exhibit erratic behavior, such as sudden braking or loss of power during acceleration, making driving unpredictable.
  • Unexpected activation of the anti-lock braking system (ABS) can occur, even in situations where braking is not necessary.

Possible Causes

Most common causes of C06C1 (ordered by frequency):

  1. The most common cause of the C06C1 code is a faulty chassis control module, with a likelihood of about 60%. This can happen due to water ingress, electrical shorts, or manufacturing defects.
  2. Another frequent cause is damaged wiring or poor connections, often leading to intermittent communication failures. This can be due to wear and tear, particularly in older vehicles.
  3. Corrosion at the connectors can also be a contributing factor, especially in regions with harsh weather conditions. Regular maintenance can help prevent this.
  4. Less common, but serious causes include software glitches in the control module that may require a software update or reprogramming.
  5. Rarely, issues with other control modules in the vehicle, such as the engine control module (ECM), can also lead to communication errors that trigger the C06C1 code.
