2. Inspect and Repair Wiring

Sub-steps:
1. Remove any covers that obstruct access to the EPS wiring harness.
2. Inspect the wiring for frays, cuts, or corrosion.
3. Repair any damaged wires by soldering and applying heat-shrink tubing.
4. Ensure all connectors are securely attached and free of corrosion.

3. Replace Steering Angle Sensor (if needed)

Sub-steps:
1. Disconnect the battery (if not already done).
2. Remove the steering wheel airbag by unscrewing the retaining screws behind the steering wheel.
3. Disconnect the airbag connector and set the airbag aside safely.
4. Unbolt and remove the steering wheel using a steering wheel puller if necessary.
5. Locate the steering angle sensor and disconnect the electrical connector.
6. Remove the sensor from its mounting location and install the new sensor.
7. Reassemble in reverse order, ensuring all components are torqued to manufacturer specifications (refer to service manual).

4. Fluid Replacement (if applicable)

Sub-steps:
