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 V and 5.2 V.
- For power supply, 5 V DC constant voltage power source can also be used.
Connect the cell battery positive terminal to the connector terminal No. 3, and the cell battery negative terminal to the connector terminal 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.
