Single Unit Inspection
DIFFERENTIAL LOCK SWITCH
1. INSPECT CONTINUITY OF DIFFERENTIAL LOCK
SWITCH
(a) Disconnect the differential lock switch connector.
(b) Check continuity between terminals 1 to 4.
Switch ON: Continuity
Switch OFF: No continuity
4WD CONTROL SOLENOID
1. INSPECT OPERATION OF 4WD CONTROL SOLENOID
Check air flow of each port when the battery voltage is
applied and is not applied to terminals No.1, No.2 of
the solenoid.
Function Inspection
DIFFERENTIAL LOCK CONTROL
INSPECT DIFFERENTIAL LOCK OPERATION
Start the engine. Check that the differential lock indica-
tor light comes on when the differential lock control
switch is turned to ON. Check that the light goes off
when the switch is turned to OFF.
HINT: After checking the system, turn the control switch
to OFF and check that the differential lock function is
released.
Reference: If the indicator light does not come on and
go out when the control switch is operated, move the
vehicle
slightly forward. when the system is operated it should
be normal.
TRANSFER VACUUM ACTUATOR
1. INSPECT ACTUATOR HOSE CONNECTION
Check that the actuator hoses are connected to the
solenoids and actuator tightly and properly.
Apply battery voltage

TRANSFER INDICATOR SWITCH
INSPECT TRANSFER INDICATOR SWITCH FOR
CONTINUITY
(a) Disconnect the indicator switch from the transfer.
(b) Check continuity between the terminals when the
switch is turned ON and when turned OFF.
Switch *ON position: Continuity
Switch OFF position: No continuity
If not, replace the indicator switch. 2. INSPECT ACTUATOR AIRTIGHTNESS
(Vacuum Tank)
(a) Disconnect the No. 1, No. 3 and No. 4 hoses from the sole-
noids.
(b) Plug the No. 3 hose.
W Connect the mighty vac to the No. 1 hose.
(d) Check the the indicator remains stable when a vacuum of
500 mmHg 0 9.69 in.Hg. 66.7 kPa) is applied.
(No. 2 Vacuum Chamber Side
(a) Disconnect the all hoses from the solenoids.
(b) Plug the No. 3 hoses.
W Connect the mighty vac to the No. 1 and No. 4 hoses.
(d) Check that the indicator remains stable when a vacuum of
500 mmHg (19.69 in.Hg, 66.7 kPa) is applied. (No. 1 Vacuum Chamber Side)
(a) Disconnect the No. 2 and No. 4 hoses form the sole-
noids.
(b) Connect the mighty vac to the No. 2 hose.
(c) Check that the indicator remains stable when a vacu-
um of 504 mmHg (19.69 in.Hg, 66.7 kPa) is applied.
