Solution

1. Preparation

Gather the necessary tools and parts listed below.
Ensure the vehicle is parked on a flat surface with the engine turned off.
Disconnect the negative terminal of the battery to prevent any electrical shorts.

2. Check Power Steering Fluid

Locate the power steering fluid reservoir under the hood.
Remove the cap and check the fluid level against the “MIN” and “MAX” marks.
If low, add the recommended power steering fluid (typically ATF or specific PS fluid) until it reaches the proper level.
Reinstall the cap securely.

3. Reset the EPS Warning Light

Reconnect the negative terminal of the battery.
Turn the ignition to the “ON” position without starting the engine.
Wait for about 10 seconds, then turn the ignition to the “OFF” position.
Start the engine and check if the EPS light goes out.
If the light remains on, repeat the process once more. If it persists, further diagnosis is required.

4. Final Checks

After resetting, take the vehicle for a short test drive to ensure the EPS system operates correctly.
Monitor the steering responsiveness and listen for any unusual noises during operation.
