4. INSPECT DIFF. LOCK CONTROL SWITCH
Inspect the switch continuity between terminals, as shown.
Switch PositionTerminalsSpecified Condition
OFF1 − 2No continuity
1 − 4No continuity
RR1 − 2No continuity
1 − 4Continuity
FR RR1 − 2Continuity
1 − 4Continuity
If continuity is not as specified, replace the switch.
5. INSPECT DIFF. LOCK POSITION SWITCH
(a) Front and Rear:

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.
Torque: 26 N·m (270 kgf·cm, 20 ft·lbf)

(g) Connect the connector and tube.
HINT:
The depth of the insertion of the bleeder tube into the
hose is approx. 15 mm (0.59 in.).
Take care that water or the equivalent will not adhere to
the connector and hose.
(h) Cancel the front differential lock.
With the ignition switch ON, turn the differential lock con-
trol switch to OFF to cancel the differential lock.
2. INSTALL REAR ACTUATOR
(a) Clean contacting surfaces of any FIPG material using gasoline or alcohol.
(b) Apply FIPG to the actuator. FIPG: Part No. 08826−00090, THREE BOND 1281 or
equivalent
HINT:
Install the actuator within 10 minutes after applying FIPG.
(c) Install the actuator to the differential and match the shaft with the shaft fork hole.
(d) Clean the threads of the set bolt and shaft fork with the white gasoline.
(e) Coat the threads of the set bolt with adhesive.
Adhesive: Part No. 08833 −00070, THREE BOND 1324
or equivalent
(f) Tighten the shift fork set bolt. Torque: 20 N·m (200 kgf·cm, 14 ft·lbf)
(g) Tighten the 4 bolts uniformly, a little at a time. Torque: 24 N·m (240 kgf·cm, 17 ft·lbf)
(h) Install the cover. (1) Clean the contacting surfaces of any FIPG material
using gasoline or alcohol.
(2) Apply FIPG to the cover.
FIPG: Part No. 08826−00090, THREE BOND 1281 or
equivalent
HINT:
Install the cover within 10 minutes after applying FIPG.

Take care that the water or the equivalent will not adhere
to the connectors and hose.
(k) Install the actuator protector. Install the protector with the 2 nuts and bolt.
Torque:
Nut: 35 N·m (360 kgf·cm, 26 ft·lbf)
Bolt: 20 N·m (200 kgf·cm, 14 ft·lbf)

HINT:
Always check the diagnostic trouble code before disconnecting
the negative ( −) terminal cable from the battery.
(b) When installing the battery, be especially careful not to in-
correctly connect the positive (+) and negative ( −) cables.
(c) Do not permit parts to receive a severe impact during re- moval or installation. Handle all SFI parts carefully, espe-
cially the ECM.
(d) Do not be careless during troubleshooting as there are numerous transistor circuits and even slight terminal con-
tact can further troubles.
(e) Do not open the ECM cover.
(f) When inspecting during rainy weather, take care to pre-
vent entry of water. Also, when washing the engine
compartment, prevent water from getting on the SFI parts
and wiring connectors.
(g) Parts should be replaced as an assembly.
(h) Care is required when pulling out and inserting wiring con-
nectors.
(1) Release the lock and pull out the connector, pulling
on the connectors.
(2) Fully insert the connector and check that it is locked.
(i) When inspecting a connector with a volt/ohmmeter (1) Carefully take out the water −proofing rubber if it is
a water−proof type connector.
(2) Insert the test probe into the connector from the wir-
ing side when checking the continuity, amperage or
voltage.
(3) Do not apply unnecessary force to the terminal.
(4) After checking, install the water−proofing rubber on
the connector securely.
(j) Use SST for inspection or test of the injector or its wiring connector.
