Rear Height Sensor: Inspection
- Connect three dry cell batteries (1.5 V) in series.NOTE:
- Use new dry-cell batteries.
- Using a circuit tester, check that the initial voltage of each dry-cell battery is 1.6 V or more. And also check that the voltage of three batteries in series is between 4.8 - 5.2 V.
- For power supply, 5 V DC constant voltage power source can also be used.
- Connect the (+) side of the battery to terminal No. 3 of the sensor, and the (-) side of the battery to terminal No. 1, and apply a voltage of 4.5 V between terminals No. 3 - No. 1.
- With voltage applied, measure the voltage between connector terminals when the sensor link is moved slowly up and down.

Terminal No. Inspection conditions Standard 2 (+) - 1 (-) Move the link within the operation range. Approx. 0.5 - 4.1 V NOTE: When the link is moved upward from the standard output position, the sensor output varies to the 0.5 V side. When the link is moved downward, the sensor output varies to the 4.1 V side. - Replace the sensor assembly - headlight beam leveler if the inspection result is not within the standard value.
