Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to avoid electrical shorts.
Ensure the vehicle is on a level surface and securely supported.

2. Inspect Electrical Connections

Locate the EPS motor and inspect the electrical connectors.
Clean the connectors using electrical cleaner, ensuring there is no corrosion.
Reconnect the connectors firmly.

3. Check and Replace Power Steering Fluid (if applicable)

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; top off if necessary.
If the fluid is dark or contaminated, drain the old fluid using a siphon pump.
Refill with the manufacturer-recommended power steering fluid type.

4. Test EPS Motor

Reconnect the battery terminal.
Start the vehicle and turn the steering wheel from lock to lock, listening for unusual noises.
Use a multimeter to check the EPS motor voltage while the steering is being turned; ensure it is within specification.

5. Clear Error Codes

Use the OBD-II scanner to clear any stored trouble codes.
Test drive the vehicle to ensure the EPS light does not return.
