Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, steering wheel puller (if needed).
Disconnect the negative battery terminal and ensure the vehicle is on a flat surface.

2. Inspect and Replace EPS Fuse

Locate the EPS fuse in the fuse box.
Remove the fuse and inspect it for any signs of damage or burn.
Replace with a new fuse of the same amperage if necessary.
Reconnect the battery terminal.

3. Repair or Replace EPS Motor and Wiring

If wiring is damaged:
- Remove any protective covers.
- Cut away damaged wiring and splice in new wire of the same gauge.
- Use heat-shrink tubing to insulate splices.
If the EPS motor is faulty:
- Disconnect the EPS motor wiring harness.
- Remove bolts securing the motor to the steering column.
- Install a new EPS motor, ensuring proper alignment and secure mounting.
- Reconnect the wiring harness.

4. Calibrate Steering Angle Sensor

Using an OBD-II scanner, access the EPS system.
Follow the manufacturer's instructions to perform the steering angle sensor calibration.
Verify that the calibration is successful before proceeding.

5. Test Drive

Reconnect the battery and start the vehicle.
Test drive to ensure that the steering assist operates normally and check for any warning lights.
