3. Use a multimeter to check the voltage at the power steering motor while turning the steering wheel. Ensure it receives the correct voltage as outlined in the service manual.

4. Component Replacement (if necessary)

Sub-steps:
1. If a faulty power steering pump is identified, remove the drive belt if applicable.
2. Unbolt the power steering pump from the bracket and disconnect the hoses.
3. Install the new power steering pump by reversing the removal steps, ensuring all connections are secure and torqued to specified values.
4. Refill the power steering fluid and bleed the system according to the manufacturer's instructions.
