COUPLING COMPONENT ASSEMBLY

id031900800600

Warning

• The engine stand is equipped with a self-lock mechanism, however, if the coupling unit is in a

tilted condition, the self-lock mechanism could become inoperative. If the coupling unit
unexpectedly rotates it could cause injury, therefore do not maintain the coupling unit in a tilted
condition. When turning the coupling unit, grasp the rotation handle firmly.

WM: DIFFERENTIAL OIL TEMPERATURE SENSOR

DIFFERENTIAL OIL TEMPERATURE SENSOR INSPECTION

id031900800700

Warning

• Hot differential oil may cause severe burns. Do not perform maintenance while differential oil is

hot.

1. Disconnect the negative battery cable.
2. Disconnect the differential oil temperature sensor connector and remove the differential oil temperature sensor.
3. Wrap the differential oil temperature sensor with

plastic wrap and immerse it into a beaker filled
with water. Gradually raise the water temperature,
and measure resistance between differential oil
temperature sensor terminals A and B.

• If not as specified, inspect the harness for

continuity. If there is normal continuity
between the terminals, replace the differential
oil temperature sensor.

4. Install the differential oil temperature sensor and connect the connector.
5. Connect the negative battery cable.
