Solution

1. Preparation

Gather required tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.
Allow the vehicle to cool if it has been running.

2. Inspect and Repair Wiring

Tools Required: Multimeter, wire splicing tools, soldering iron (if needed)
Inspect the wiring harness connected to the EPS motor for frays or breaks.
Use a multimeter to test for continuity between wires.
Repair or replace damaged wiring as necessary, ensuring all connections are secure and insulated.

3. Replace EPS Motor (if necessary)

Tools Required: Socket set, torque wrench
Remove the EPS motor by unbolting it from its mount.
Disconnect the electrical connector from the EPS motor.
Install the new EPS motor by reversing the removal steps, ensuring to torque bolts to manufacturer specifications (typically around 25 Nm, check your service manual).
Reconnect the electrical connector securely.

4. Calibration of Steering Angle Sensor

Tools Required: OBD-II scanner with live data functionality
After replacing the EPS motor, connect the battery terminal.
Use an OBD-II scanner to access the steering angle sensor calibration function.
Follow the on-screen prompts to calibrate the sensor correctly.
