Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and ensure the engine is off.

2. OBD-II Code Retrieval

Tools Required: OBD-II scanner
Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the "On" position without starting the engine.
Retrieve and record any EPS-related fault codes.

3. Inspect and Replenish Power Steering Fluid

Tools Required: Funnel, power steering fluid
Locate the power steering fluid reservoir.
Check the fluid level; if low, add the recommended type of power steering fluid until it reaches the proper level.
Inspect the fluid for contamination; if dirty, consider a fluid flush.

4. Check Electrical Connections

Tools Required: Multimeter
Disconnect the battery negative terminal to ensure safety.
Visually inspect the wiring harness connected to the EPS motor for frays or corrosion.
Use a multimeter to check for continuity in the wiring.
Reconnect any loose connections and repair any damaged wiring.

5. Test EPS Motor Function

Tools Required: Multimeter
With the battery reconnected, measure the voltage at the EPS motor connector while the steering wheel is turned.
Ensure the voltage is within the specifications; if not, further diagnosis of the EPS control unit may be necessary.
If the motor is faulty, proceed to replace it.

6. Replace EPS Motor (if necessary)

Tools Required: Socket set, torque wrench
Disconnect the battery negative terminal.
Remove any components obstructing access to the EPS motor.
Disconnect the wiring harness and remove the bolts securing the EPS motor.
Install the new EPS motor, ensuring it is properly aligned and secured.
