Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check and Refill Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level using the dipstick.
If low, add manufacturer-recommended power steering fluid to the appropriate level.
Reinstall the cap securely.

3. Inspect and Repair Wiring

Examine the wiring harness connected to the EPS motor and steering column.
Look for frayed wires, loose connections, or corrosion.
Repair or replace any damaged wiring or connectors as needed.

4. Replace EPS Motor (if necessary)

If diagnostics indicate a malfunctioning EPS motor, proceed to replace it:
- Disconnect electrical connectors from the EPS motor.
- Remove the mounting bolts securing the EPS motor using a socket set.
- Carefully extract the motor from its housing.
- Install the new EPS motor in reverse order, ensuring proper alignment.
- Torque the mounting bolts to manufacturer specifications.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Clear any diagnostic codes using the OBD-II scanner.
Start the vehicle and turn the steering wheel left and right to check for proper function.
