Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and safety gloves.
Disconnect the negative battery terminal to prevent any electrical shorts.

2. Replace Fuse/Relay (if faulty)

Locate the fuse box under the dashboard or engine bay.
Identify the fuse for the EPS system using the owner's manual.
Remove the faulty fuse and replace it with a new one of the same amperage.
If the relay is faulty, remove the old relay and install a new one.

3. Repair or Replace Wiring/Connectors (if damaged)

Visually inspect all wiring and connectors leading to the EPS motor and sensor.
Repair any damaged insulation or connections using electrical tape or heat-shrink tubing.
Replace any corroded connectors with new ones.

4. Replace EPS Motor (if faulty)

Remove the steering column covers to access the EPS motor.
Disconnect the electrical connector and remove the mounting bolts securing the EPS motor.
Install the new EPS motor by reversing the removal steps.
Reconnect the electrical connector and ensure all fastenings are tight.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Clear any stored codes using the OBD-II scanner.
Start the vehicle and check if the power steering assist functions correctly.
