Solution

1. Preparation

Gather tools including a socket set, OBD-II scanner, and multimeter.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Check Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; it should be between the minimum and maximum marks.
If low, top off with the appropriate power steering fluid (consult owner’s manual).
Inspect the fluid for contamination (dark color or debris); if contaminated, consider a fluid flush.

3. Inspect Steering Components

Raise the front of the vehicle using a jack and secure it with jack stands.
Visually inspect the steering rack for any leaks or signs of wear.
Check the steering column for any loose bolts or damaged components.
Ensure that the electric power steering motor is securely mounted and free of corrosion.

4. Test Electric Power Steering Motor

Use a multimeter to check voltage at the EPS motor connector while turning the steering wheel.
If no voltage is detected, trace the wiring back to the control module and check for any breaks or shorts.
If the motor is faulty, replace it according to manufacturer specifications.

5. Wheel Alignment and Tire Check

Inspect all tires for proper inflation and any signs of uneven wear.
If tires are worn or misaligned, perform a wheel alignment and replace tires as needed.
Ensure that all suspension components are secure and free of damage.
