Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to avoid any electrical issues.

Tools Required:

OBD-II scanner
Socket set
Torque wrench
Fluid container
Power steering fluid (as specified in the owner’s manual)

2. Inspect Power Steering Fluid

Locate the power steering reservoir.
Remove the cap and check the fluid level against the markings.
If low, add the recommended power steering fluid until it reaches the correct level.

3. Check for Leaks

Visually inspect hoses and connections for any signs of fluid leakage.
If you find leaks, replace the damaged hoses or fittings.
Clean any spilled fluid to ensure accurate future inspections.

4. Inspect Steering Components

Lift the front of the vehicle using a jack and secure it with jack stands.
Check the steering rack for any physical damage or corrosion.
Inspect the tie rods and ball joints for wear; replace as necessary.

5. Test Electric Power Steering Motor

Reconnect the battery and turn the ignition to the "ON" position without starting the engine.
Use a multimeter to check the voltage at the electric power steering motor connector; compare with manufacturer specifications.
If the voltage is incorrect, further diagnose the wiring or replace the motor.

6. Reassemble and Test Drive

Ensure all components are tightened to the manufacturer’s torque specifications.
Reconnect the battery and start the vehicle.
Test the steering response by performing a test drive, checking for improvements in handling and response.
