Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to prevent any electrical shorts.

2. Check Power Steering Fluid

Locate the power steering reservoir.
Remove the cap and check the fluid level; top off with the recommended fluid if low.
Inspect the fluid for contamination or a burnt smell; if contaminated, proceed to the next step.

3. Replace Power Steering Fluid (if necessary)

Using a siphon or turkey baster, remove old fluid from the reservoir.
Refill with new OEM-approved power steering fluid.
Start the engine and turn the steering wheel from lock to lock to purge air from the system.

4. Inspect and Repair Electrical Connections

Visually inspect the wiring harness connected to the EPS motor for any signs of wear or damage.
Clean any corroded connectors with electrical contact cleaner.
Reconnect any loose or damaged wires.

5. Check and Replace EPS Motor (if necessary)

If testing indicated a failure in the EPS motor, remove the mounting bolts using a socket set and carefully detach the motor from the steering column.
Install the new EPS motor by reversing the removal steps, ensuring all connectors are properly secured.
Torque the mounting bolts to the manufacturer specifications.

6. Reconnect Battery and Test

Reconnect the battery terminals.
Start the vehicle and check if the EPS light is still illuminated.
Test the steering response during a short drive.
