Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, fluid catch pan.
Disconnect the battery to ensure safety while working on the electrical system.
Allow the vehicle to cool down if the engine has been running.

2. Check and Top Off Power Steering Fluid

Locate the power steering fluid reservoir (refer to the owner's manual for exact location).
Remove the cap and check the fluid level; top off with the recommended fluid type if low.
Inspect for any leaks around the reservoir and hoses. Replace any damaged components.

3. Inspect and Repair Wiring and Connections

Remove the EPS control module cover (if applicable) to access the wiring.
Use a multimeter to check for continuity in wires and ensure the ground connections are secure.
Repair any damaged wires or connectors. If necessary, replace the EPS control module.

4. Replace EPS Motor (if faulty)

Disconnect the battery and remove the steering column covers.
Unplug the EPS motor connector and unbolt the motor from the steering rack.
Install the new EPS motor, ensuring it is securely fastened.
Reconnect the wiring and covers.

5. Calibration

Reconnect the battery and start the vehicle.
Use the OBD-II scanner to perform a steering angle sensor calibration.
Follow the scanner's instructions to complete the calibration process.
