Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Inspect and Replace EPS Fuse

Locate the fuse box (check owner’s manual for specific location).
Remove the fuse related to the power steering using a fuse puller.
Inspect the fuse for continuity; replace it if blown with a fuse of the same amperage.

3. Repair or Replace Wiring and Connectors

Visually inspect the EPS wiring harness and connectors for any damage.
Clean any corrosion from connectors using electrical contact cleaner.
If any wiring is damaged, repair or replace it as necessary.

4. Test and Replace EPS Motor (if needed)

Reconnect the negative battery terminal.
Turn the ignition to the "ON" position without starting the engine.
Use a multimeter to test the EPS motor voltage while turning the steering wheel.
If the motor does not respond, remove it from the vehicle and replace it with a new unit.
- Tools Needed: Socket set, torque wrench.
- Installation Steps:
  - Disconnect the EPS motor connector.
  - Remove mounting bolts and carefully take out the motor.
  - Install the new motor, torque bolts to manufacturer specifications.
  - Reconnect the motor connector.

5. Calibrate Steering Angle Sensor

Use a scan tool to access the steering angle sensor calibration procedure.
Follow the prompts on the scan tool to complete the calibration successfully.
