Diagnostic Steps for 'Power Steering Assist Fault'

Here are the steps you can take to troubleshoot and potentially fix the 'power steering assist fault' yourself:

1. Check the Battery

Charge the Battery: Ensure that the battery is fully charged. A weak battery can lead to various electrical issues including power steering faults.

Inspect Battery Connections: Make sure the battery terminals are clean and securely connected. Corrosion can cause poor electrical connections.

Visual Inspection: Look for any damaged wires or loose connectors related to the power steering system. Ensure everything is properly connected.

7. Check the Power Steering Pump

If the power steering pump is not functioning correctly, it may need to be replaced. Listen for any unusual noises when you turn the steering wheel, which could indicate a failing pump.

8. Consult the Owner’s Manual

Refer to Your Vehicle’s Manual: For specific troubleshooting steps related to the power steering system, refer to your vehicle’s owner’s manual.
