CHECK VEHICLE HEIGHT SENSOR OUTPUT SIGNAL.

1) Connect three dry cell batteries (1.5 V) in series.

2) Connect the (+) side of the battery to the No. 3 terminal of the sensor body, and the (−) side of the battery to terminal No. 1, to apply a voltage of 4.5 V between terminals No. 3 — No. 1.

3) With voltage applied, use a tester to measure the voltage between the No. 2 — No. 1 terminals when the sensor body link is moved slowly up and down.
