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 any electrical shorts.

2. Check Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level. If low, fill it to the recommended level using the manufacturer's specified fluid type.
Inspect for any leaks around hoses and fittings. If leaks are found, replace the damaged components.

3. Inspect Electrical Connections

Reconnect the battery terminal.
Check the wiring harness and connectors for any visible damage.
Clean any corrosion from connectors using electrical contact cleaner.
Re-secure any loose connections.

4. Test Power Steering Motor

Reconnect the battery terminal.
Use a multimeter to measure the voltage at the power steering motor while turning the steering wheel.
If voltage is present and the motor does not respond, replace the power steering motor.

5. Replace Power Steering Control Module (if necessary)

Remove any covers obstructing access to the power steering control module.
Disconnect the electrical connectors from the module.
Unscrew the module from its mounting points and replace it with a new one.
Reconnect the electrical connectors and ensure they are secured properly.

6. Final Checks

Reconnect the negative battery terminal.
Start the vehicle and turn the steering wheel lock to lock to bleed any air from the system.
Check for any leaks and ensure proper operation of the steering system.
