Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, basic hand tools (sockets, wrenches), power steering fluid.
Ensure the vehicle is parked on a level surface and the ignition is off.

2. Clear Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the "ON" position without starting the engine.
Use the scanner to clear any stored EPS-related error codes.
Turn off the ignition and disconnect the scanner.

3. Inspect and Refill Power Steering Fluid

Locate the power steering reservoir.
Check the fluid level against the dipstick or markings on the reservoir.
If low, add the manufacturer-recommended power steering fluid until it reaches the proper level.
Inspect for leaks around hoses and connections.

4. Test Battery Voltage

Use a multimeter to measure the battery voltage; it should be between 12.4V and 12.7V.
If the voltage is low, charge the battery or replace it if necessary.
Inspect battery terminals for corrosion and ensure they are tight.

5. Inspect Wiring and Connectors

Visually inspect the wiring harness connected to the EPS motor and control module.
Look for any frayed wires, loose connections, or corrosion.
If any issues are found, repair or replace the damaged components as needed.

6. Test the EPS Motor

Disconnect the EPS motor connector.
Use a multimeter to check for continuity and resistance according to the manufacturer's specifications.
If the motor fails the test, replace the EPS motor.
