Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.
Ensure the vehicle is on a level surface and safely secured.

2. Inspect and Replace the EPS Fuse

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Remove the cover and identify the EPS fuse using the diagram on the fuse box lid.
Use a fuse puller or pliers to remove the fuse and visually inspect it for blown elements.
Replace with a new fuse of the same amperage rating if blown.

3. Check and Repair Wiring

Visually inspect the EPS wiring harness for cuts, abrasions, or corrosion.
Use a multimeter to check continuity across the wiring.
Repair or replace damaged wires or connectors as necessary.

4. Test and Replace EPS Motor (if needed)

Reconnect the battery and turn the ignition to the ON position.
Measure the voltage at the EPS motor connector using a multimeter; it should match the specifications in the service manual.
If the voltage is correct but the EPS motor is unresponsive, replacement may be necessary.
Remove the EPS motor by disconnecting the electrical connector and unbolting it from the steering column.
Install the new EPS motor in reverse order and torque bolts to manufacturer specifications.

5. Reassembly and Final Checks

Reconnect any components removed during the process.
Reconnect the battery terminal.
Start the engine and turn the steering wheel to ensure power steering is functioning properly.
