is in the extent between zero and 5 degrees clockwise
above the center line of the actuator.
If the matchmarks is not in this extent, rotate the pinion to be
matched. Do not supply the battery positive voltage directly be-
tween terminals. If the matchmarks come to the extension limit
of the rotation, do not electrify moreover.

HINT:
When a signal enters the ECU to LOCK the front dif ferential and
set the rear differential to FREE (when battery positive voltage
is inputted to terminal 6 (RF) of ECU and about 0 V is inputted
to terminal 12 (R)), or a signal to FREE both the front and rear
differentials, the indicator lights keep blinking until the ignition
switch is turned off (Fail−safe function).
If the circuit is not as specified, check and repair or replace the
trouble part shown in the table above.
(b) Inspect the battery positive voltage Battery positive voltage: 10 − 14.5 V
(c) Inspect the system circuit with connector connected (1) Turn the ignition switch to the ON position.
(2) Keep the center Diff. lock condition.
(3) Remove the Diff. lock ECU.
(4) Using a voltmeter, measure the voltage when thedifferential lock control switch is in the position, as
shown below.

INSTALLATION
1. INSTALL FRONT ACTUATOR
(a) Check that the outermost rack tooth of the shift fork is
virtually above the center line of the actuator installation
hole.
(b) Using a dry cell battery, alig n the matchmark on the pinion
with the center line of the actuator.
NOTICE:
If the pinion of the actuator is not in the specified
place, the actuator is difficult to be installed.
Do not supply the battery positive voltage between
terminals.
If the matchmark comes to the extension limit of the
rotation, do not electrify moreover.
(c) Install a new O−ring to the actuator.
(d) Apply a light coat of gear oil on the O −ring.
(e) Apply MP grease to the gear part of the actuator.
(f) Install the actuator to the differential with the 2 nuts and bolt, so that the outermost rack tooth of the shift fork will
fit matchmark of the pinion of the actuator.
HINT:
Do not damage the O −ring of the actuator.

PRECAUTION
1. BEFORE WORKING ON FUEL SYSTEM, DISCON-
NECT NEGATIVE (−) TERMINAL CABLE FROM THE
BATTERY.
HINT:
Any diagnostic trouble code retained by the computer will be
erased when the negative ( −) terminal cable is disconnected.
Therefore, if necessary, read the diagnosis before disconnect-
ing the negative ( −) terminal cable from the battery.
2. DO NOT SMOKE OR WORK NEAR AN OPEN FLAME WHEN WORKING ON FUEL SYSTEM.
3. KEEP GASOLINE AWAY FROM RUBBER OR
LEA TH-
ER PARTS
4. MAINTENANCE PRECAUTIONS
(a) In event of engine misfire, these precautions should be taken.
(1) Check proper connection of battery terminals, etc.
(2) Handle high −tension cords carefully.
(3) After repair work, check that the ignition coil termi- nals and all other ignition system lines are recon-
nected securely.
(4) When cleaning the engine compartment, be espe-
cially careful to protect the electrical system from
water.
(b) Precautions when handling the oxygen sensor. (1) Do not allow the oxygen sensor to drop or hit
against an object.
(2) Do not allow the sensor to come in contact with wa- ter.
5. IF VEHICLE IS EQUIPPED WITH MOBILE RA-
DIO
SYSTEM (HAM, CB, ETC.)
If the vehicle is equipped with a mobile communication system,
refer to the precaution in the IN section.
6. AIR INDUCTION SYSTEM
(a) Separation of the engine oil dipstick, oil filler cap, PCV hose, etc. may cause the engine to run out of tune.
(b) Disconnection, looseness or cracks in the parts of the air
induction system between the throttle body and cylinder
head will allow air suction and cause the engine to run out
of tune.
7. ELECTRONIC CONTROL SYSTEM
(a) Before removing SFI wiring connectors, terminals, etc., first disconnect the power by either turning the ignition
switch OFF or disconnecting the negative ( −) terminal
cable from the battery.
