Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal for safety.

2. Inspect and Replace Fuses

Locate the fuse box and identify the EPS fuse.
Remove the EPS fuse and inspect it for continuity using a multimeter.
Replace the fuse if it is blown, using the correct amperage as specified in the owner's manual.

3. Inspect Wiring and Connectors

Reconnect the battery terminal.
Remove the covers around the steering column if necessary.
Check all wiring harnesses for fraying, corrosion, or loose connections.
Repair or replace damaged wiring as needed.

4. Replace EPS Motor (if necessary)

If the EPS motor is faulty, disconnect the battery again.
Remove the steering column covers for access to the EPS motor.
Disconnect the wiring harness from the EPS motor.
Unbolt the EPS motor from its mount using the appropriate socket set.
Install the new EPS motor by reversing the removal steps, ensuring all connections are secure.

5. System Reset and Calibration

Reconnect the battery terminal.
Turn the ignition to the ON position without starting the engine to allow the system to initialize.
Perform a steering angle sensor calibration using a scan tool if required.
