What is C0609?
DTC C0609 indicates a problem with the Steering Column Control Module (SCCM). This module is critical for the functionality of various steering and safety features in your vehicle. When the SCCM fails or has a communication issue, it can trigger this diagnostic trouble code. Common symptoms include a malfunctioning steering wheel controls, issues with the airbag system, or problems with electronic stability control. For example, on models like the 2015-2018 Chevrolet Silverado, drivers might experience erratic behavior from the steering wheel controls, such as failure to activate the horn or cruise control. This can be concerning as it may impact vehicle safety. Ignoring this code can lead to more severe electrical issues or even failure of safety features like the airbag deployment system during an accident. Therefore, addressing DTC C0609 promptly is essential for maintaining vehicle safety and performance.
