Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle's battery to ensure safety while working on electrical components.

2. Inspect and Replace Fuse

Locate the EPS fuse in the fuse box.
Use a fuse puller or pliers to remove the fuse and check for continuity.
If blown, replace it with a new fuse of the same amperage.

3. Check and Replace EPS Motor

Locate the EPS motor, typically found on or near the steering column.
Disconnect the electrical connector from the EPS motor.
Remove any mounting bolts securing the motor using a socket set.
Replace with a new EPS motor and reattach the electrical connector.

4. Test and Calibrate Steering Angle Sensor

Reconnect the battery and turn the ignition to the "ON" position without starting the engine.
Use a scan tool to access the steering angle sensor data and verify it is within specification.
If calibration is needed, follow the manufacturer's specific calibration procedure using the diagnostic tool.

5. Final Assembly

Reinstall any covers or components that were removed during the inspection.
Ensure all connections are secure and no tools are left in the engine bay.
