C006C is a diagnostic trouble code (DTC) that indicates an issue with the Ryker's electric throttle control system. This code is triggered when the Vehicle Control Module (VCM) detects an incorrect signal or voltage from one of the sensors in the system, usually indicating a malfunctioning component. A C006C DTC can cause symptoms such as reduced engine power and acceleration, engine stalling, and difficulty starting. If this code appears on your Ryker's dashboard display, it's important to take your vehicle into a qualified repair shop right away so they can properly diagnose and fix any underlying issues before they become more serious.
