Auto Leveling Sensor Inspection
- Remove the auto leveling sensor. (See AUTO LEVELING SENSOR REMOVAL/INSTALLATION .)
- Prepare three dry cell batteries (1.5 V ).
- Connect the three dry cell batteries in a series.
- Connect the positive pole of the dry cell battery to auto leveling sensor terminal C, and the negative pole to terminal A.
- Connect the tester as shown in the figure with approx. 4.5 V of voltage applied between auto leveling sensor terminals A and C, and measure the voltage at auto leveling sensor terminal B.
- When slowly moving the auto leveling sensor link up and down, verify that the voltage fluctuates linearly between 0.5-4.5 V
as shown in the figure.
- If the voltage cannot be verified as indicated in the graph, replace the auto leveling sensor. (See AUTO LEVELING SENSOR REMOVAL/INSTALLATION .)
