Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a level surface.
Disconnect the negative battery terminal to prevent electrical shock.

2. Inspect and Replace EPS Fuse

Locate the fuse box under the dashboard or in the engine compartment.
Remove the cover and identify the EPS fuse using the diagram on the cover.
Use a multimeter to check for continuity in the fuse.
If the fuse is blown, replace it with one of the same amperage.

3. Fluid Check and Replacement

Locate the power steering fluid reservoir.
Check the fluid level and condition; it should be clear, not dark or contaminated.
If necessary, drain the old fluid using a siphon pump and replace it with the manufacturer-recommended EPS fluid.
Purge air from the system by turning the steering wheel from lock to lock several times.

4. Wiring Inspection and Repair

Inspect the wiring harness connected to the EPS motor for any fraying, breaks, or loose connections.
Clean any corroded terminals with electrical contact cleaner.
Repair or replace damaged wiring as necessary.

5. Test and Replace EPS Motor (if applicable)

If previous steps do not resolve the issue, test the EPS motor by applying direct power.
If the motor fails to operate, remove it from the vehicle.
Install a new EPS motor by following the manufacturer’s specifications for torque values and connection points.
