Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and turn off the ignition.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace EPS Fuse

Locate the fuse box under the dashboard or engine bay.
Remove the cover and identify the EPS fuse using the diagram.
Use a fuse puller to remove the fuse and inspect it.
If blown, replace it with a fuse of the same amperage rating.

3. Check and Refill Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level against the markings on the dipstick.
If low, add the manufacturer-recommended power steering fluid until it reaches the proper level.

4. Inspect Wiring and Connectors

Visually examine the wiring harness connected to the EPS motor and steering column.
Look for frayed wires, loose connections, or corrosion.
If damage is found, repair or replace the affected wiring or connectors.

5. Test EPS Motor Voltage

Reconnect the battery terminal.
Turn the ignition to the "ON" position without starting the engine.
Use a multimeter to test voltage at the EPS motor connector.
Ensure it reads the manufacturer-specified voltage. If not, check the supply wiring for faults.

6. Replace EPS Motor (if necessary)

If the EPS motor is faulty, remove the retaining bolts securing it to the steering assembly.
Disconnect the electrical connector and remove the motor from its housing.
Install the new EPS motor and reconnect the electrical connector and securing bolts to the manufacturer-specified torque.
