Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle's 12V battery to ensure safety while working on electrical components.
Allow the vehicle to cool down if it has been recently driven.

2. Inspect Power Steering Fluid

Locate the power steering reservoir.
Check the fluid level; top off with the recommended fluid type if low.
If the fluid is contaminated, drain and replace it.

3. Check Electrical Connections

Reconnect the battery if disconnected.
Inspect the wiring harness connected to the power steering motor for wear or disconnections.
Secure any loose connections and repair damaged wiring.

4. Test the Power Steering Motor

Using a multimeter, check the voltage at the power steering motor while turning the steering wheel.
If voltage is absent or inconsistent, further testing of the steering control module may be necessary.

5. Inspect Steering Components

Lift the front of the vehicle using a jack and secure it with jack stands.
Check the steering rack for any visible damage or excessive play.
Inspect the steering linkage for wear or looseness, replacing components as needed.

6. Reassemble and Test Drive

Reattach any components removed during inspection.
Reconnect the battery and clear any error codes.
Test drive the vehicle to verify the proper function of the steering system.
