Solution

1. Preparation

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

2. Inspect and Replace EPS Fuse

Locate the fuse box (usually near the driver’s side dashboard).
Remove the cover and identify the EPS fuse using the diagram.
Check the fuse for continuity; if blown, replace it with the same amperage fuse.
Reinstall the fuse box cover.

3. Inspect EPS Motor and Wiring

Remove any covers obstructing access to the EPS motor.
Visually inspect the EPS motor for any signs of damage or overheating.
Check the wiring harness for frayed wires or corrosion.
If damaged, repair or replace the wiring harness as necessary.

4. Test EPS Motor

Reconnect the battery terminal.
Use a multimeter to check the voltage at the EPS motor connector while the ignition is on.
If voltage is present but the motor does not operate, replace the EPS motor.

5. Steering Calibration (if applicable)

Use a diagnostic tool to perform a steering angle sensor calibration.
Follow the tool's instructions to ensure the EPS system is reset and calibrated correctly.
