Removal of the steering wheel allows the contact coil to
turn freely but do not turn the contact coil (on the combi-
nation switch) more than allowable number of turns
(about two and a half turns from the center position
clockwise or counterclockwise respectively), or coil will
break.

5) Remove steering wheel (1) with special tool.
Special tool
(A) : 09944-36011
INSTALLATION
1) Check that vehicle’s front tires are at straight-ahead position.
If equipped with air bag system, align contact coil to original
position referring to “Centering Contact Coil” in this section.
2) Install steering wheel as follows.
For vehicle without air bag system
a) Apply grease to contact plate (1).
“A” : Grease 99000-25290
b) Install steering wheel onto shaft, aligning them by match
marks.
For vehicle with air bag system
Install steering wheel to steering shaft with 2 lugs (2) on con-
tact coil fitted in two grooves (3) in the back of steering wheel
and also aligning marks (4) on steering wheel and steering
shaft. CAUTION:

For vehicle with air bag system
a) Install driver air bag (inflator) module to steering wheel.
Refer to “Driver Air Bag (Inflator) Module” in this section.
Centering contact coil (for vehicle with air bag sys-
tem)
1) Check that vehicle’s wheels (front tires) are set at straight-
ahead position.

3) Turn contact coil counterclockwise slowly with a light force till
contact coil will not turn any further. NOTE:
After installing the steering wheel, turn the steering
wheel about 1 full rotation so that the cancel cam pin fits
into the pin hole in the steering wheel and then check the
turn signal lever for proper function.
NOTE:
Contact coil can turn about 5 turns at maximum, that is, if
it is at the center position, can turn about two and a half
turns both clockwise and counterclockwise.

rotate shaft to assure that steering shaft (2) is locked.
5) Tighten new bolts until head of each bolt is broken off.
6) Turn ignition key to “ACC” or “ON” position and check to be
sure that steering shaft rotates smoothly. Also check for lock
operation.
7) Install steering column referring to “Steering Column” in this
section.
Steering Lower Shaft
REMOVAL
1) Turn steering wheel so that vehicle’s front tires are at
straight-ahead position.
2) Turn ignition switch to “LOCK” position and remove key. NOTE:
Use care not to damage aluminum part of steering lock
body with center punch.
CAUTION:
For vehicle with air bag system
Never turn steering wheel while steering shaft lower joint
is removed.
Should it have been turned and contact coil (on combina-
tion switch) have got out of its centered position, it needs
to be centered again. Also, turning steering wheel more
than about two and a half turns will break contact coil.

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).
