Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the negative battery terminal to prevent electrical shock.
Allow the vehicle to sit for a few minutes to discharge any residual electrical energy.

2. Inspect and Replace Faulty Components

a. Fuse and Relay

Check the power steering fuse in the fuse box.
If blown, replace with a new fuse of the same amperage.
Inspect the power steering relay; replace if faulty.

b. Wiring and Connections

Visually inspect all wiring harness connections related to the EPS system.
Clean any corroded connectors using electrical contact cleaner.
Repair or replace damaged wiring as necessary.

3. Replace Steering Angle Sensor (if required)

Locate the steering angle sensor, typically found on the steering column.
Disconnect the wiring harness from the sensor.
Remove the mounting screws and gently pull the sensor out.
Install the new sensor in the reverse order and reconnect the wiring.

4. Reconnect Battery and Reset System

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any error codes and reset the EPS system.

5. Test Drive

Take the vehicle for a test drive to ensure that the steering operates smoothly and that the warning light is off.
