Solution

1. Preparation

Tools Required: Socket set, wrench set, fluid catch pan, funnel, OBD-II scanner
Disconnect the negative battery terminal to avoid electrical shorts.
Allow the vehicle to sit for a few minutes to ensure systems are inactive.

2. Check Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level using the dipstick attached to the cap or by visual inspection.
If fluid is low, top off with the manufacturer-recommended power steering fluid.
Safety Warning: Do not overfill the reservoir.

3. Inspect Power Steering Pump

Locate the power steering pump, typically mounted on the front of the engine.
Check for any visible signs of fluid leaks around the pump and hoses.
Start the engine and listen for any unusual noises from the pump. If the pump is noisy or leaking, it may need replacement.

4. Reset Steering Angle Sensor (if applicable)

If the power steering warning light is illuminated, a reset may be needed.
Use the OBD-II scanner to access the vehicle’s body control module.
Follow the scanner’s instructions to reset the steering angle sensor, if applicable.

5. Recheck Connections

Ensure that all battery terminals are securely connected and that there is no corrosion.
Inspect the wiring harness connected to the power steering system for any loose or damaged connections.
