ACC CUT RELAY
INSPECTION
1. REMOVE ACC CUT RELAY
Remove the relay box and ACC cut relay.
2. INSPECT ACC CUT RELAY CONTINUITY
(a) Using an ohmmeter, check that there is continuity be-
tween terminals 1 and 2.
If there is no continuity, replace the relay.
(b) Check that there is no continuity between terminals 3 and
5.
If there is continuity, replace the relay.
(c) Check that there is continuity between terminals 3 and 4.
If there is no continuity, replace the relay.
3. INSPECT ACC CUT RELAY OPERATION
(a) Apply battery positive voltage across terminals 1 and 2.
(b) Using an ohmmeter, check that there is no continuity be-
tween terminals 3 and 4.
If there is continuity, replace the relay.
(c) Using an ohmmeter, check that there is continuity be-
tween terminals 3 and 5.
If there is no continuity, replace the relay.
4. REINSTALL ACC CUT RELAY

tween terminals 1 and 2.
If there is no continuity, replace the relay.
(b) Check that there is no continuity between terminals 3 and
5.
If there is continuity, replace the relay.
3. INSPECT RELAY OPERATION

3. INSPECT DIFF. LOCK COMPONENTS
(a) Inspect the relay operation.
(1) Jack up the vehicle.
(2) Use a heater main relay and connect it, as shown
below.
NOTICE:
Connect the terminals being careful not to touch the neigh-
boring terminals or metallic parts of the relay housing.
(3) Rotate the tire and check that differential lock has
occurred.
If operation is not as specified, replace the actuator.
(b) Inspect the diff. lock control switch continuity.
Inspect the switch continuity between terminal 1 to termi-
nal 4.
HINT:
If continuity dose not exist, replace the switch.
(c) Inspect the diff. lock indicator switch.
(1) Check that continuity between exists terminals
when the switch is pushed (differential connected
position).
(2) Check that no continuity exists when the switch is
free (differential disconnected position).
HINT:
If operation is not as specified, replace the switch.

INSPECTION
1. INSPECT SWITCH POSITION
(a) Start the engine, and shift the transfer shift lever to the ºHº
position.
(b) Check that the center diff. indicator light comes on when
the the switch is in ºONº position. Check that the light goes
off when the switch is in ºOFFº position.
2. INSPECT SHIFT LEVER POSITION
(a) Start the engine, and turn the center diff. lock switch to
OFF.
(b) Check that the center diff. indicator light comes on when
the transfer shift lever is shifted to the ºLº position. Check
that the light goes off when the lever is shifted to the ºNº
or ºHº position.
3. INSPECT CENTER DIFF. LOCK CONTROL RELAY
(a) Check that continuity exists between each terminal, as
shown in the chart.
Tester connected terminal numberSpecified condition
1 - 2Continuity
2 - 4Continuity
6 - 7*
*: There is a diode between the terminals 6 and 7.
If no continuity exists, check that continuity exists when chang-
ing the position of
probe for the position of negative  probe
of tester.
(b) Apply battery positive voltage between each terminal and
check that continuity exists between each terminal, as
shown in the chart.

4. INSPECT ACTUATOR OPERATION
(a) Raise up the front wheels, place the stopper under the
rear wheels to block them, and pull up the parking brake.
(b) Disconnect the connector of the actuator and connect it
to the relay using wire.
(c) Check that the front propeller shaft can be rotated by
hand.

HINT:
When inspecting the operation described above, use a heater
main relay.
NOTICE:
Connect the terminals being careful not to touch the neigh-
boring terminals or metallic parts of relay housing.
5. INSPECT MOTOR ACTUATOR (MOTOR)
(a) Remove the motor actuator (See page TR-8).
(b) Measure the resistance between the terminals 1 and 5.
Standard resistance: 0.3 - 100 W
(c) Measure the resistance between the terminals 1 or 5 and
body ground.
Standard resistance: More than 0.5 MW
If the resistance value is not as specified, replace the motor ac-
tuator.
