    1. Disconnect the height control sensor connector.
    2. Remove the height control sensor.
    3. Connect 3 dry batteries of 1.5 V in series.
    4. Connect terminal 2 to the batteries' positive (+) terminal, and terminal 3 to the batteries' negative (-) terminal, then apply voltage about 4.5 V between terminals 2 and 3.
    5. Measure the voltage between terminals 1 and 3, when the height control sensor link is slowly moved up and down.
