Solution

1. Preparation

Tools Required: Socket set, OBD-II scanner, fluid catch pan, safety goggles, gloves.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; it should be between the "MIN" and "MAX" marks.
If fluid is low, top it off with the recommended power steering fluid type for your model.

3. Inspect the Power Steering Pump

Reconnect the battery.
Start the engine and listen for unusual noises from the power steering pump.
If noises are present, remove the pump:
1. Disconnect the power steering lines using a wrench.
2. Unbolt the pump from its mounting bracket.
3. Remove the pump for further inspection or replacement.

4. Examine the Steering Rack and Tie Rods

Raise the front of the vehicle using jack stands.
Inspect the steering rack for leaks or physical damage.
Check the tie rods for play or wear; replace if necessary.

5. Electrical Connections

With the battery reconnected, check the wiring harness and connectors to the power steering control module for corrosion or loose connections.
If necessary, clean the connectors and ensure they are securely attached.

6. Test Drive

After completing the repairs, take the vehicle for a test drive to ensure proper steering assist functions.
Monitor for any warning lights or abnormal noises during operation.
