WARNING:
When handling an air bag (inflator) module, be sure to
read “Service Precautions” given earlier in this section
and observe each instruction. Failure to follow them
could cause a damage to the air bag (inflator) module or
result in personal injury.
WARNING:
Never disassemble driver air bag (inflator) module or
measure its resistance. Otherwise, personal injury may
result.
CAUTION:

Components and Functions
Component Function
4WD switch When the transfer shift lever is shifted to 4L or 4H position from 2H, this switch
turns ON and cause the 4WD control system to turn ON.
4WD controller When the 4WD switch turns on, the 4WD controller activates VSV2 to lock the
air locking hubs and when it receives an “ON” signal from the vacuum switch, it
makes VSV2 to complete operation within 5 seconds and causes the 4WD indi-
cator light to light up.
If vacuum in the vacuum circuit fails to reach the specified level due to a leakage
in the vacuum circuit (when no “ON” signal is inputted from the vacuum switch),
the 4WD controller stops operation of VSV2 in 15 seconds and makes the 4WD
indicator light to flash to warn occurrence of a trouble.
When the 4WD switch turns off, the 4WD controller activates VSV1 for 10 sec-
onds to unlock the hubs and at the same time makes the 4WD indicator light
turn off.
VSV1 VSV1 operates according to the signal from the 4WD controller. When it is acti-
vated, the port opens and vacuum in the intake manifold is applied through the
vacuum circuit to unlock to the slide gear in the air locking hub. As a result, the
air locking hubs are unlocked.
VSV2 VSV2 operates according to the signal from the 4WD controller. When it is acti-
vated, the port opens and vacuum in the intake manifold is applied through the
vacuum circuit to lock to the slide gear in the air locking hub. As a result, the air
locking hubs are locked.
Vacuum switch When VSV2 receives the “ON” signal from 4WD switch, vacuum is applied
through its circuit to the vacuum switch. The vacuum switch turns on when it
detects vacuum exceeding 260 mmHg.
“4WD” indicator lamp It lights up when 4WD control system is in the 4WD mode.
It flashes to warn that locking hub operation has not completed (4WD control
system fails to shift 4WD).

OPERATION
2WD
→ 4WD
When the transfer shift control lever is shifted from the 2WD (2H) position to the 4WD (4H or 4L) position, a 4WD
“ON” signal is transmitted to the 4WD controller which then activates VSV2 to apply vacuum in the intake mani-
fold to the chamber “B” in the hub housing.
When vacuum is applied, the slide gear is separated from the magnet, moves toward the center of the vehicle
body and gets engaged with the outer gear. In this way, the front axle shaft and the front wheel hub rotate as one
unit.
If vacuum in the circuit fails to reach 260 mmHg within 15 seconds after operation of VSV2 due to such trouble
as a hole in the vacuum pipe, the slide gear does not operate and the 4WD indicator light flashes to warn that
the hub is unlocked.

4WD
→ 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.

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.
