Overview of the Ford Fusion Power Steering Assist System
In the Ford Fusion, Power Steering Assist is a feature that uses an electric motor to provide power assistance to the steering system. This feature helps to reduce the effort required to turn the steering wheel, especially at low speeds or when parking.
The system is controlled by a Power Steering Control Module (PSCM), which uses sensors to monitor the vehicle’s speed, steering angle, and other parameters to adjust the electric motor’s level of assistance.
However, a fault with the PSCM or other components of the system leads to the Power Steering Assist Fault issue, which makes steering difficult or unsafe.
