Solution

1. Preparation

Gather tools and materials: OBD-II scanner, multimeter, socket set, torque wrench, and any necessary replacement parts.
Disconnect the vehicle battery to ensure safety while working on the electrical system.

2. Inspect and Replace EPS Fuse

Locate the EPS fuse in the fuse box (refer to the owner's manual for specific location).
Remove the fuse using a fuse puller or pliers.
Inspect the fuse for continuity; replace it if blown.
Reinsert the fuse securely into the fuse box.

3. Repair Wiring Connections

Visually inspect the wiring harness connected to the EPS motor.
Look for frayed wires, loose connections, or corrosion.
Repair or replace any damaged wiring or connectors as necessary.
Use electrical cleaner to clean any corroded terminals before reconnecting.

4. Test and Replace EPS Motor (if necessary)

Using a multimeter, test the voltage supply to the EPS motor while the vehicle is turned on (check manufacturer specifications for correct voltage).
If the EPS motor is not receiving adequate voltage, trace the wiring back to the source.
If the motor is faulty, remove it by unbolting it from the steering column.
Install a new EPS motor, ensuring all connections are secure and torqued to manufacturer specifications.
