What adjustment is necessary when inspecting a vehicle with power steering?

When inspecting a vehicle with power steering, it is necessary to ensure that the engine is running. This is because the power steering system relies on hydraulic pressure generated by the engine to function properly. Without the engine running, the power steering pump will not operate, making it impossible to assess the effectiveness of the system.

Inspecting while the engine is running allows the inspector to check for any abnormal sounds, assess the responsiveness of the steering, and identify any potential leaks or issues with the power steering system. In this state, the power steering can also be tested under load, providing a complete picture of its performance and safety.

Other aspects such as fluid level checking and turning the wheels by hand are important but should follow the initial assessment where the system's functionality can be observed.
