Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace EPS Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Remove the cover and identify the EPS fuse using the diagram on the cover.
Check the fuse for continuity with a multimeter; replace it if blown.

3. Check Wiring and Connectors

Visually inspect the wiring harness leading to the EPS motor for any frayed wires or corrosion.
Disconnect the connectors and clean them with an electrical contact cleaner.
Reconnect the connectors ensuring they are secure and free of debris.

4. Test EPS Motor Voltage

Reconnect the battery and turn the ignition to the ON position (do not start the engine).
Using a multimeter, measure the voltage at the EPS motor connector.
If voltage is absent or incorrect, trace back to the EPS control module for further testing.

5. Inspect Power Steering Fluid (If Applicable)

Check the power steering fluid reservoir for the correct fluid level (refer to the owner's manual for specifications).
If the fluid is low, fill it with the recommended type of fluid; check for leaks in the system.

6. Replace EPS Control Module (If Necessary)

If the control module is found to be faulty, locate it (usually near the EPS motor).
Disconnect the battery, then remove any components obstructing access to the module.
Unplug the old control module and install the new one, reconnecting all necessary wiring.
Reassemble any components removed during the process.
