Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, torque wrench, power steering fluid, and a multimeter.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Disconnect the vehicle's 12V battery to prevent any electrical issues while working on the steering system.

2. Inspect Power Steering Fluid

Locate and remove the power steering fluid reservoir cap.
Check the fluid level; add manufacturer-recommended power steering fluid if low.
If the fluid appears dark or contaminated, proceed to replace it.

3. Replace Power Steering Fluid (if necessary)

Place a drain pan under the power steering system.
Disconnect the return line from the power steering pump.
Allow old fluid to drain completely.
Reconnect the line and refill the reservoir with new power steering fluid.
Bleed the system by turning the steering wheel from lock to lock several times to remove air bubbles.

4. Inspect and Replace Power Steering Pump (if needed)

If the pump shows signs of failure, remove the serpentine belt and disconnect the pump from the mounting brackets.
Remove the power steering lines from the pump.
Install the new power steering pump, ensuring all connections are secure and torqued to specifications.
Reinstall the serpentine belt.

5. Test Steering System

Reconnect the 12V battery.
Start the vehicle and check for proper function of the power steering assist.
Test drive the vehicle at low speeds to ensure steering responsiveness has improved.
