Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative battery terminal to ensure safety while working on the electrical system.

2. Check and Replace Fuses

Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the power steering fuse using the fuse diagram.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse for any signs of damage; if blown, replace it with a new fuse of the same amperage.

3. Inspect and Repair Wiring

Visually inspect the wiring harness connecting the EPS motor and control module.
Look for frayed wires, corrosion, or loose connections.
Repair or replace any damaged wiring or connectors.

4. Test and Replace EPS Motor (if necessary)

If the EPS motor is suspected to be faulty, disconnect it from the harness.
Using a multimeter, check the motor for continuity and proper resistance.
If the motor is defective, replace it with a new EPS motor following the manufacturer's guidelines.
- Install the new motor and reconnect the wiring harness securely.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and check for any warning lights on the dashboard.
Test the steering function by turning the steering wheel at various speeds.
