Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and screwdrivers.
Ensure the vehicle is on a flat surface and the ignition is off. Disconnect the battery to prevent any electrical issues.

2. Inspect and Repair Wiring

Remove the steering column cover using a screwdriver.
Visually inspect the wiring harness connected to the EPS motor for any frayed wires or poor connections.
If damaged, repair or replace the wiring as necessary.

3. Fluid Check and Replacement

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level. If low, top it up with the manufacturer-recommended fluid type.
If the fluid is dark or contaminated, drain and replace it with fresh fluid.
Reattach the reservoir cap securely.

4. Test EPS Motor

Reconnect the battery and use a multimeter to check the voltage at the EPS motor connector.
If the voltage is outside the specified range, trace back to the power supply circuit for issues.
If the motor is unresponsive, it may need replacement.

5. Steering Angle Sensor Calibration

Use the OBD-II scanner to access the EPS system.
Follow the manufacturer's procedure to recalibrate the steering angle sensor if needed.
Clear any stored fault codes after calibration.
