Solution

1. Preparation

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

2. Replace EPS Fuse

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Remove the cover and identify the EPS fuse using the diagram on the cover.
Use a fuse puller or needle-nose pliers to remove the fuse.
Inspect for any signs of a blown fuse and replace it with a new fuse of the same amperage.

3. Inspect and Repair Wiring

Reconnect the negative battery terminal and turn the ignition to the "ON" position.
Use a multimeter to check the voltage at the EPS motor connector.
If voltage is absent, trace the wiring back to the fuse box, looking for breaks or damage.
Repair or replace any damaged wiring or connectors.

4. Replace EPS Motor (if necessary)

If the motor is faulty, remove the steering column cover to access the EPS motor.
Disconnect the motor's electrical connector and remove the mounting bolts.
Carefully take out the old motor and install the new EPS motor.
Reconnect the electrical connector and secure the motor with the mounting bolts to the specified torque.

5. Final Assembly and Testing

Reinstall any steering column covers that were removed.
Reconnect the negative battery terminal.
Start the vehicle and check for the EPS warning light.
Test the steering for proper operation and ensure no unusual noises are present.
