Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, fluid pump, socket set, torque wrench.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative battery terminal for safety.

2. Fluid Inspection and Replacement

Remove the power steering reservoir cap.
Check the fluid level; if low, top off with the manufacturer's recommended power steering fluid.
If the fluid appears dark or contaminated, drain the old fluid:
- Locate the power steering fluid return line.
- Place a drain pan under the connection point and disconnect the line.
- Allow old fluid to drain completely.
- Reconnect the line and refill the reservoir with new fluid.

3. Electrical System Check

Reconnect the battery and turn on the ignition (do not start the engine).
Use the OBD-II scanner to check for error codes related to the power steering system.
If any codes are found, follow the vehicle-specific service manual to address the issues.
Use a multimeter to check the voltage at the power steering motor connector while turning the steering wheel:
- If voltage is absent or unstable, trace the wiring back to the power source for faults.

4. Inspect Components

Visually inspect the steering column and joints for any signs of wear, looseness, or damage.
Check the serpentine belt for wear and tension; replace if it is frayed or loose according to the manufacturer’s specifications.

5. Reassembly and Final Checks

After addressing any issues, reassemble any components that were removed.
Ensure all connections are tight and secure.
Test the vehicle's steering in a safe area before taking it on the road.
