Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety while working on the EPS system.

2. Inspect and Replace EPS Fuse

Locate the fuse box, typically under the dashboard or hood.
Remove the cover and check the EPS fuse (refer to owner's manual for specific fuse location).
If blown, replace with a fuse of the same amperage.

3. Check and Add Power Steering Fluid

Locate the power steering fluid reservoir.
Inspect fluid level; if low, top off with the recommended type of power steering fluid (refer to owner's manual for specifications).
Look for any signs of leaks around hoses and connections; repair any leaks as necessary.

4. Test and Repair Wiring Connections

Using a multimeter, test the voltage at the EPS motor connector while the ignition is in the "ON" position.
If no voltage is present, trace back to the EPS control module and check wiring for damage or loose connections.
Repair any damaged wiring or replace connectors as needed.

5. Replace EPS Motor (if necessary)

If the EPS motor is faulty, remove the steering column cover to access the EPS motor.
Disconnect the electrical connectors and remove any bolts securing the motor to the steering assembly.
Install the new EPS motor in reverse order, ensuring all connections are secure.
