Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, basic hand tools, replacement fuses (if needed).
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to prevent accidental electrical shorts.

2. Inspect EPS Fuse

Locate the fuse box (refer to the owner’s manual for the exact location).
Remove the EPS fuse (typically labeled) and visually inspect it for damage.
Use a multimeter to check for continuity. Replace if necessary.

3. Check Power Steering Fluid

Locate the power steering fluid reservoir.
Open the cap and check the fluid level; it should be between the ‘MIN’ and ‘MAX’ marks.
If low, add the recommended type of power steering fluid as per the owner’s manual.

4. Inspect EPS Motor and Wiring

Remove any covers to access the EPS motor and wiring harness.
Inspect the motor for any physical damage or corrosion.
Check the wiring harness for loose connections or frayed wires; repair as needed.

5. Test EPS System Voltage

Reconnect the battery and power on the vehicle.
Using a multimeter, measure the voltage at the EPS motor connector while turning the steering wheel.
Ensure the voltage is within the manufacturer's specifications (check service manual for exact values).

6. Verify Steering Angle Sensor Operation

Connect the OBD-II scanner and navigate to the EPS section.
Check the readings from the steering angle sensor to ensure they are within the normal range.
If readings are abnormal, recalibrate or replace the sensor as necessary.
