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.

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.
