Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Inspect and Replace the EPS Fuse and Relay

Locate the fuse box under the dashboard and identify the EPS fuse.
Use a multimeter to check for continuity. If faulty, replace the fuse with one of the same amperage.
Locate the EPS relay, remove it, and test it for continuity. Replace if defective.

3. Check and Refill Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check fluid level against the dipstick. If low, add the recommended power steering fluid until it reaches the full mark.
Inspect for any leaks around the reservoir and hoses.

4. Repair or Replace Damaged Wiring and Connectors

Visually inspect the wiring harness and connectors for signs of wear, fraying, or corrosion.
If damaged, repair the wiring using appropriate soldering techniques or replace the entire harness if necessary.
Ensure all connections are secure and free of debris.

5. Test and Replace the EPS Motor (if necessary)

Reconnect the battery terminal and turn the ignition to the "ON" position without starting the engine.
Use a multimeter to test the EPS motor's voltage and ground connections.
If the motor is unresponsive or faulty, remove it from the steering column and replace it with a new EPS motor.
