Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, basic hand tools (screwdrivers, socket set).
Ensure the vehicle is on a level surface and in park with the engine off.

2. Replace EPS Fuse (if necessary)

Locate the fuse box and identify the EPS fuse.
Remove the fuse and inspect it for continuity.
If blown, replace it with a new fuse of the same amperage.

3. Repair or Replace Wiring/Connectors

If any damaged wiring or connectors are found during inspection, repair or replace as necessary.
Ensure all connections are secure and free of corrosion.

4. Replace EPS Motor (if necessary)

Disconnect the vehicle battery before working on the EPS motor.
Remove any covers or components obstructing access to the EPS motor.
Disconnect the EPS motor cables and remove the mounting bolts.
Install the new EPS motor by reversing the removal steps.
Reconnect the battery.

5. Calibrate the Steering Angle Sensor

Using an OBD-II scanner, access the EPS system.
Follow the manufacturer's instructions for steering angle sensor calibration.
