Fuses and Relays
Fuses and relays protect the electrical system from overloads and short circuits. Inspect the fuse box for any blown fuses and replace them if necessary. Relays are also located in the fuse box and can be tested using a multimeter to ensure they are functioning correctly.
Wiring Harnesses
Wiring harnesses connect the various electrical components in the power steering assist system. Inspect the wiring harnesses for any damage or corrosion, especially at the points where they connect to components. Loose or damaged wiring can cause intermittent or complete failure of the power steering assist system.
Electrical Connections
Electrical connections between components are essential for proper functioning of the power steering assist system. Inspect the electrical connections for any signs of corrosion or loose connections. Clean or tighten any loose connections and replace any corroded connectors.
Multimeter Testing
A multimeter can be used to test electrical connections and components. Set the multimeter to the appropriate setting (voltage, resistance, or continuity) and test the connections and components according to the manufacturer’s specifications.
Power Steering Pump Inspection
The power steering pump is a crucial component of the power steering assist system, responsible for generating the hydraulic pressure that assists in steering the vehicle. It is driven by the engine’s serpentine belt and converts rotational motion into hydraulic pressure.
Visual Inspection
Visually inspect the power steering pump for any leaks or damage. Look for signs of fluid seepage around the pump body, hoses, or connections. Also, check for any cracks or physical damage to the pump housing or its components.
Fluid Level and Condition
Check the power steering fluid level and condition. Locate the power steering fluid reservoir, usually a translucent plastic container with markings indicating the fluid level. Ensure the fluid level is between the “Min” and “Max” marks. Inspect the fluid for any discoloration, contamination, or burnt smell, which may indicate a need for fluid replacement or further diagnosis.
Steering Rack Inspection
The steering rack is a vital component of the power steering assist system, responsible for translating the rotational motion of the steering wheel into linear motion that turns the wheels. It consists of a齿条and pinion mechanism, with the齿条connected to the steering wheel and the pinion connected to the steering linkage.
When the steering wheel is turned, the齿条moves along the pinion, causing the steering linkage to move and turn the wheels.
Visual Inspection
Begin by visually inspecting the steering rack for any leaks or damage. Look for signs of fluid seepage or corrosion around the rack housing and seals. Check for any loose or damaged mounting bolts or brackets that could affect the rack’s alignment or stability.
Bushings and Ball Joints Inspection
The steering rack is supported by bushings and ball joints, which allow for movement and articulation while maintaining proper alignment. Check the bushings for any signs of wear, cracking, or excessive play. Inspect the ball joints for any looseness or damage to the boot that could indicate wear or contamination.

If any of these components are worn or damaged, they should be replaced to ensure proper steering operation and prevent further issues.
Power Steering Lines and Hoses
The power steering lines and hoses are essential components of the power steering assist system, responsible for transmitting hydraulic fluid from the power steering pump to the steering rack. They ensure proper fluid circulation and pressure, enabling smooth and effortless steering.
Visual Inspection
Regular visual inspections of the power steering lines and hoses are crucial to detect any potential leaks or damage. Look for any cracks, abrasions, or loose connections along their length. Pay special attention to areas where the hoses connect to the pump, steering rack, and other components.
Power Steering Fluid Pressure Check
Measuring the power steering fluid pressure using a pressure gauge is a valuable diagnostic step. Connect the gauge to the designated test port on the power steering system and start the engine. The gauge should read within the manufacturer’s specified pressure range.
Deviations from the expected pressure may indicate a problem with the power steering pump, lines, or hoses.
Computer Module and Software
The computer module plays a crucial role in the power steering assist system of the Ford Fusion. It serves as the central control unit, processing inputs from various sensors and providing appropriate commands to the power steering system components.
The software within the computer module contains the necessary algorithms and instructions to manage the power steering assist functionality. Updates to this software may become available to address potential issues or introduce enhancements to the system’s performance.
Updating Software and Reprogramming Computer Module
If a software update is available for the computer module, it is recommended to have it performed by a qualified technician. The process involves connecting a diagnostic tool to the vehicle’s computer system and downloading the updated software. Once the update is complete, the technician may also perform a reprogramming procedure to ensure the computer module is properly configured for the updated software.
Resetting the System
Resetting the power steering assist system after repairs or replacements is crucial to ensure its proper operation. It clears any stored fault codes and recalibrates the system to its optimal settings.
There are two methods to reset the system:
Using a Diagnostic Scanner, How to fix power steering assist fault ford fusion
