Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the vehicle's battery to prevent any electrical shorts during repair.
Allow the vehicle to cool if it has been running.

2. Inspect and Replace EPS Fuse and Relay

Locate the fuse box and identify the EPS fuse using the diagram on the cover.
Remove the EPS fuse using a fuse puller and inspect it; replace if blown.
Locate the EPS relay, remove it, and test it for continuity. Replace if faulty.

3. Check and Replace Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check fluid level; if low, top up with manufacturer-recommended fluid.
If fluid is contaminated, drain the system completely and refill with new fluid.

4. Repair or Replace EPS Motor

Disconnect the electrical connector from the EPS motor.
Remove the mounting bolts securing the EPS motor to the steering column.
Replace with a new EPS motor if testing indicates failure; follow the manufacturer’s specifications for installation.

5. Reassemble and Connect Battery

Reinstall any components removed during the procedure.
Reconnect the vehicle's battery and ensure all connections are secure.
