Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is on a level surface and engage the parking brake.
Disconnect the negative terminal of the battery to avoid electrical shock.

2. Check and Replace Fuses

Locate the fuse box (refer to the owner’s manual).
Identify the EPS fuse and remove it with a fuse puller.
Inspect the fuse for continuity; replace it if blown with a fuse of the same amperage.

3. Inspect and Repair Wiring

Visually inspect the EPS wiring harness and connectors.
If any damage is found, repair or replace the affected wiring.
Ensure all connectors are securely attached and free from corrosion.

4. Test and Replace EPS Motor (if necessary)

If the EPS motor shows no voltage output, remove the motor from the steering column.
Disconnect the electrical connector and mounting bolts.
Install the new EPS motor by reversing the removal steps and ensuring all connections are tight.

5. Reconnect Battery and Test

Reconnect the negative terminal of the battery.
Start the vehicle and check for error codes again to ensure the problem is resolved.
Test drive the vehicle to confirm that power steering is functioning properly.
