Solution

1. Preparation

Gather tools and parts required.
Disconnect the negative battery terminal to prevent electrical shorts.
Ensure the vehicle is on a level surface and securely parked.

2. Check and Replace Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Identify the EPS fuse (refer to the owner’s manual for the exact location).
Use a fuse puller or needle-nose pliers to remove the EPS fuse.
Inspect the fuse for continuity and replace it with a new fuse of the same amperage if blown.

3. Inspect and Refill Power Steering Fluid

Locate the power steering fluid reservoir (usually near the front of the engine bay).
Remove the cap and check the fluid level; if low, add the manufacturer-recommended power steering fluid.
If the fluid is dark or contaminated, consider flushing the system.

4. Inspect EPS Motor and Connections

Visually inspect the EPS motor and wiring harness for any signs of damage, wear, or corrosion.
Ensure all connectors are securely attached and free of corrosion.
If damaged, replace the EPS motor or repair the wiring as needed.

5. Battery and Charging System Check

Use a multimeter to measure the battery voltage; it should be approximately 12.6 volts when the engine is off and around 13.7 to 14.7 volts when running.
If the voltage is below specifications, recharge or replace the battery as necessary.

6. Steering Angle Sensor Calibration

Connect a compatible diagnostic tool to the OBD-II port.
Access the EPS calibration function and follow the on-screen instructions to calibrate the steering angle sensor.
Turn the steering wheel fully left and right several times as indicated by the tool to complete the calibration.
