Solution

1. Preparation

Gather necessary tools: OBD-II scanner, multimeter, socket set, torque wrench, and power steering fluid.
Ensure the vehicle is parked on a level surface and turn off the ignition. Disconnect the vehicle's 12V battery to prevent electrical shock.

2. Inspect and Replace Power Steering Fluid

Sub-steps:
1. Locate the power steering reservoir under the hood.
2. Remove the cap and check the fluid level. If low, top it off with the manufacturer-recommended power steering fluid.
3. If the fluid appears dirty or contaminated, proceed to drain and replace it.
4. Use a siphon pump to remove old fluid from the reservoir.
5. Refill with new power steering fluid and replace the cap.

3. Inspect and Replace Power Steering Pump

Sub-steps:
1. Remove any covers or components obstructing access to the power steering pump.
2. Disconnect the electrical connector from the power steering pump.
3. Unbolt the pump from its mounting location using the appropriate socket.
4. Install the new power steering pump in the reverse order of removal, ensuring to torque the bolts to the manufacturer’s specifications.
5. Reconnect the electrical connector and any components removed during disassembly.

4. Reconnect Battery and Test

Sub-steps:
1. Reconnect the vehicle's 12V battery and ensure all connections are secure.
2. Turn on the ignition and allow the power steering system to initialize.
3. Check for any error messages on the dashboard.
4. Test the steering response by turning the wheel left and right while stationary, then take the vehicle for a short test drive.
