1. Disconnect the negative battery cable..
2. Remove the auto leveling sensor..
3. Prepare three dry cell batteries (1.5 V
).
4. Connect the three dry cell batteries in a series.

5. Connect the positive pole of the dry cell battery to auto leveling sensor terminal C, and the negative pole to terminal A.

6. 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.

7. 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.

A/C Unit Disassembly/Assembly
1. Disassemble in the order indicated in the table.
CAUTION:
If a non-specified grease is used, it may result in abnormal noise or improper
operation of the links. Apply only the specified grease to each link.
2. Assemble in the reverse order of disassembly.

Thermostat
Purpose, Function
When the engine coolant temperature is low, the thermostat blocks the engine
coolant passage between the radiator and engine. As a result, because engine
coolant cycles without passing through the radiator, warming is promoted.
Construction
The thermostat ...
