What vehicles are most commonly affected by C063C?
C063C is commonly found in 2015-2020 Chevrolet and GMC models, including the Silverado, Sierra, and Equinox. Check for recalls or Technical Service Bulletins (TSBs) related to this issue.
How can I prevent C063C from happening again?
Routine maintenance, including electrical system checks and keeping connectors dry, can help prevent C063C. Regular inspections can catch issues before they escalate.
What is C063C?
The Diagnostic Trouble Code (DTC) C063C indicates a problem with the chassis control module, particularly in the communication with other vehicle systems. This code is often seen in various Chevrolet and GMC models from 2015 to 2020. The chassis control module is crucial as it manages many aspects of vehicle dynamics, including stability control, anti-lock braking systems, and traction control. When C063C is triggered, it suggests that the chassis control module has detected an internal malfunction or is unable to communicate effectively with other modules. This can lead to a number of performance issues, such as reduced stability control or malfunctioning braking systems, which can pose serious safety risks. Additionally, drivers may notice warning lights on the dashboard, particularly the check engine light or stability control light. Ignoring this code can lead to further complications and higher repair costs down the line, so prompt diagnosis and resolution are essential. In many cases, a thorough inspection of wiring and connections, as well as testing of the module itself, is required to determine the root cause of the issue.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C063C is present:
- The check engine light activates and remains illuminated, indicating a fault in the vehicle's systems.
- Drivers may experience irregular vehicle handling, such as skidding or loss of traction during acceleration, which can be alarming.
- Fuel efficiency may decline, with reports of a decrease in miles per gallon by 10-15%, indicating a larger systemic issue.
- Inconsistent operation of stability control features may occur, leading to a lack of confidence while driving.
- Dashboard warning lights for traction control or anti-lock braking systems may frequently illuminate, signaling a malfunction.
Possible Causes
Most common causes of C063C (ordered by frequency):
- The most common cause is a faulty chassis control module, which accounts for around 60% of cases. This can be due to internal failures or software issues.
- Loose or damaged wiring and connectors in the system can cause intermittent communication failures between the chassis module and other components.
- Water ingress or corrosion in the chassis control module can lead to malfunction. Regular inspections can help prevent this.
- Less common but serious causes include a complete failure of the power supply to the chassis control module, which requires immediate attention.
- Rarely, issues with other control modules communicating with the chassis control module can lead to this code being triggered.
