→ 2WD
When the transfer shift control lever is shifted from the 4WD (4H or 4L) to the 2WD (2H) position, the 4WD con-
troller activates VSV1 and the intake manifold vacuum is applied to the chamber “A” in the hub housing. As the
slide gear is shifted to the wheel side by the vacuum force and disengaged from the outer gear, rotation of the
front wheel hub is not transmitted to the front axle shaft.

4WD Controller and ITS Circuit Check
VOLTAGE CHECK
Check for input or output voltage of 4WD controller (1) (voltage
between each circuit and body ground) with 4WD controller con-
nector connected and ignition switch turned START (engine run).
* : With engine runningCAUTION:
Disable air bag system (if equipped with Air Bag), refer
to “Disabling Air Bag System” in Section 10B.
This check must be carried out in a well-ventilated
place.
