Solution

1. Preparation

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

2. Inspect and Replace Fuse

Locate the fuse box (usually under the dashboard or engine compartment).
Remove the EPS fuse using a fuse puller.
Check the fuse visually or using a multimeter; replace if blown.
Reinstall the fuse and reconnect the battery terminal.

3. Check Wiring and Connections

Inspect the wiring harness connected to the EPS motor for damage.
Disconnect the EPS connector and clean any corrosion with electrical cleaner.
Reconnect the harness ensuring a snug fit.

4. Test EPS Motor

With the battery reconnected, use a multimeter to measure voltage at the EPS motor connector while turning the steering wheel.
If voltage is present and the motor does not operate, replace the EPS motor.

5. Calibration of EPS System

Use a specialized diagnostic scanner to access the EPS system settings.
Follow on-screen instructions to calibrate the steering angle sensor as required.

6. Final Assembly

Reconnect any removed components and ensure all connections are secure.
Test drive the vehicle to confirm that the power steering is functioning properly.
