Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, multimeter, steering wheel puller (if necessary).
Ensure the vehicle is parked on a level surface and the ignition is off. Disconnect the negative battery terminal to prevent electrical shorts.

2. Check Power Steering Fluid (If Applicable)

Locate the power steering fluid reservoir.
Inspect the fluid level; if low, top off with the recommended fluid type as per the owner's manual.
If the fluid is dirty or contaminated, consider flushing the system.

3. Inspect and Test Electric Power Steering Motor

Reconnect the battery and turn the ignition to the ON position (do not start the vehicle).
Use the OBD-II scanner to check for any logged error codes related to the power steering system.
If codes are present, follow the manufacturer's guidelines to troubleshoot the specific issue.
If no codes are present, test the power steering motor using a multimeter to ensure it receives the appropriate voltage and is functioning properly.

4. Inspect Steering Components

Visually inspect the steering column for any obstructions, such as debris or damaged components.
Check for wear on the steering rack and tie rods.
If needed, remove the steering wheel using a steering wheel puller to access the column and inspect for internal damage or binding.

5. Alignment and Tire Pressure Check

Verify that all tires are inflated to the manufacturer's recommended pressure.
If the steering issue persists, consider performing a wheel alignment to ensure proper handling and tire wear.
