Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface, engage the parking brake, and disconnect the negative battery terminal for safety.

2. Inspect and Replace EPS Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Remove the EPS fuse using a fuse puller or needle-nose pliers.
Inspect the fuse for continuity; if blown, replace it with a new fuse of the same amperage.

3. Check and Repair Wiring

Inspect the wiring harness connected to the EPS motor and ECU for any signs of wear, fraying, or damage.
If damage is found, repair the wiring with solder and heat-shrink tubing or replace the harness if necessary.

4. Test and Replace EPS Motor (if necessary)

If the motor is not functioning correctly, remove it from the steering column.
Disconnect the electrical connector and unscrew the mounting bolts.
Replace the EPS motor with a new unit, ensuring it is correctly aligned and secured.

5. Reassemble and Reconnect

Reconnect all electrical connectors and ensure they are secure.
Reinstall the fuse and reconnect the negative battery terminal.
Start the vehicle and check for any warning lights on the dashboard.
