What is C0632?
DTC C0632 refers to a fault detected in the Steering Control Module, which is a critical component in modern vehicles that helps manage the steering system effectively. When this code appears, it signals that the module has detected an issue that could affect steering performance, possibly leading to unsafe driving conditions. This code is commonly found in vehicles such as the 2014-2020 Chevrolet Silverado and GMC Sierra. If your vehicle's steering feels loose or unresponsive, or if you experience difficulty maneuvering, you may be facing issues related to this code. Drivers might notice that the vehicle's stability control features are disabled, which can lead to challenges in maintaining control during sharp turns or sudden maneuvers. Ignoring DTC C0632 can lead to more significant problems down the line, including increased wear on other steering components, potential safety hazards, and could even result in steering failure. Therefore, it’s crucial to address this issue promptly to ensure safe vehicle operation and prevent further damage.
