Solution

1. Preparation

Gather tools: OBD-II scanner, fluid siphon, socket set, torque wrench, and a multimeter.
Ensure the vehicle is parked on a level surface and the engine is off before beginning work.

2. Inspect and Replace Power Steering Fluid

Remove the cap from the power steering fluid reservoir.
Use a siphon to extract old fluid from the reservoir.
Inspect the fluid for contamination (discoloration, debris).
Refill the reservoir with manufacturer-recommended power steering fluid.
Start the vehicle and turn the steering wheel from lock to lock to purge air from the system.

3. Check and Repair Leaks

Visually inspect all power steering hoses and connections for leaks.
If leaks are found, replace the affected hoses and ensure all clamps are tight.
If the power steering pump is leaking, remove the pump by:
- Disconnecting the power steering lines.
- Unbolting the pump from its mount (refer to torque specifications in the service manual).
Install the new pump, ensuring all connections are secure and properly torqued.

4. Electrical Component Check

Inspect the power steering fuse and replace it if blown.
Use a multimeter to check voltage at the power steering assist motor.
If no voltage is detected, trace wiring for damage or corrosion and repair as needed.
