The test is checking how the system’s pressure relief valve behaves. When you close the valve on the steering system analyzer, the hydraulic circuit is isolated and pressure builds up. The relief valve should open at its specified setting to prevent overpressure, then reseat when the valve is opened again. Closing the valve multiple times and noting the readings checks that the relief valve seats properly, leaks aren’t present, and the system holds and releases pressure at the correct level. If the pressure readings reach and hold at the expected relief setting and cycle consistently, the relief valve is functioning. If the readings are off—too low, too high, or unstable—the relief valve or its seating may be faulty. This test targets the relief valve specifically; the pump or steering gear aren’t being directly validated by this isolation-and-readings procedure, and the fluid isn’t a component you measure by pressure reading in this test.
