The 2014 Chevrolet Silverado’s electric power steering system integrates an electromechanical unit housing the power steering control module, sensors, motor, belt drive, and ball nut mechanism. This module is crucial for controlling power steering assist and is located within the power steering assist motor assembly. It’s important to note that the module is replaced as a complete unit and is not serviceable separately from the motor assembly. This integrated design simplifies repairs and ensures proper functionality.
The power steering control module on the 2014 Silverado is not independently replaceable and comes as part of the entire power steering motor assembly. This assembly is typically located on the steering column, near the steering gear. Accessing the module requires removing components like the steering column shroud and potentially other related parts. While the exact location can vary slightly, consulting a repair manual specific to the 2014 Silverado will provide precise instructions and diagrams.
This module plays a critical role in features like Smooth Road Shake Compensation. This software function actively counteracts vibrations felt in the steering wheel caused by tire imbalances at highway speeds. By sensing and reducing torque fluctuations, it enhances driving comfort and stability. The system is designed to compensate for a specific range of imbalance, ensuring effectiveness within typical driving conditions.
The system also compensates for road crown, utilizing input from the steering wheel angle sensor. This sensor determines the intended driving direction, sending data to the Electronic Brake Control Module (EBCM). While infrequent, if a lead/pull condition arises, re-centering the steering wheel angle sensor is necessary, and should be done before a wheel alignment. This ensures accurate steering input and proper vehicle control.
The torque sensor, vital for measuring steering effort, is integrated within the steering gear pinion. Unlike the power steering control module, the torque sensor is serviced as part of the steering gear assembly. Understanding the distinct locations and service procedures for these components is crucial for accurate diagnosis and repair of steering system issues.
