Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety during the repair.

2. Inspect and Replace EPS Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Remove the cover and locate the EPS fuse.
Check the fuse visually or use a multimeter to test for continuity.
If blown, replace the fuse with one of the same amperage.

3. Check and Repair Wiring and Connections

Inspect the wiring harness connected to the EPS motor for frays or corrosion.
Disconnect the EPS motor connectors carefully.
Clean the connectors with electrical contact cleaner, ensuring a good connection.
If damaged, repair or replace wiring as necessary.

4. Replace EPS Motor (if necessary)

If diagnostics indicate an EPS motor failure, proceed to replace the motor:
- Remove any covers or panels obstructing access to the EPS motor.
- Disconnect the EPS motor wiring harness.
- Remove the mounting bolts using a socket set.
- Carefully pull the EPS motor out and replace it with a new unit.
- Torque the mounting bolts to the manufacturer specifications.

5. Reassemble and Test

Reconnect all connectors and panels removed during the repair.
Reconnect the negative battery terminal.
Start the vehicle and check for EPS warning lights.
Test the steering functionality by turning the wheel at various speeds.
