Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.
Ensure the vehicle is on a level surface and supported securely.

2. Inspect and Replace Power Steering Fuse

Locate the fuse box in the engine compartment or passenger side.
Remove the cover and find the power steering fuse (refer to the owner's manual for the correct fuse ID).
Use a multimeter to check for continuity in the fuse. If it is blown, replace it with a fuse of the same amperage.

3. Check and Clean Battery Connections

Inspect battery terminals for corrosion; clean with a wire brush if necessary.
Ensure the connections are tight. If the battery is weak, replace it with a fully charged unit.

4. Inspect EPS Motor and Wiring

Remove any protective covers to access the EPS motor.
Visually inspect the motor for physical damage or loose connections.
Check wiring harness for fraying or exposed wires. Repair or replace as necessary.

5. Test and Replace Steering Angle Sensor

Disconnect the steering angle sensor connector.
Use a multimeter to test the sensor's output; it should indicate changing resistance as the steering wheel is turned.
If it is faulty, replace the steering angle sensor by unbolting it and connecting the new unit.

6. Check EPS Control Module

Use the OBD-II scanner to check for any stored codes related to the EPS control module.
If the module is found to be faulty, replace it by unbolting it from its mount and disconnecting the wiring harness.
