Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle's battery to prevent electrical shorts.
Allow the vehicle to cool down if it has been recently driven.

2. Check Power Steering Fluid

Locate the power steering fluid reservoir under the hood.
Remove the cap and check the fluid level; add manufacturer-recommended fluid to the appropriate level if low.
Inspect fluid for signs of contamination or discoloration; replace if necessary.

3. Inspect EPS Motor and Wiring

Visually inspect the EPS motor mounted on the steering column for any signs of wear or damage.
Check the wiring harness for frayed wires, corrosion, or loose connections.
If damaged wiring is found, repair or replace as necessary.

4. Test EPS System Voltage

Reconnect the battery and turn the ignition to the ON position without starting the engine.
Use a multimeter to measure voltage at the EPS motor connector; it should match manufacturer specifications (typically around 12V).
If voltage is not present, trace the wiring back for faults.

5. Reset EPS System

Use a compatible diagnostic tool to access the EPS control module.
Follow the tool's instructions to perform a system reset.
Clear any stored fault codes and verify that the EPS warning light is no longer illuminated.
