Rotating the tires, check they are in the differential lock condi-
tion.
(d) Disconnect the cable from the negative terminal of the battery.

DIFFERENTIAL LOCKING SYSTEM
ON−VEHICLE INSPECTION
1. INSPECT DIFFERENTIAL LOCK SYSTEM
(a) Inspect the indicator lights.
Check that the indicator lights (front side and rear side)
light up for approx. 1 second when the ignition switch is
turned ON.
(b) Inspect the differential lock operation. (1) Jack up the vehicle then start the engine.
(2) Put the transfer shift lever on the L position.
(3) When the Diff. lock control switch is set to the RR
position, the indicator light (rear side) is turned on.
Differential lock is applied to the rear wheel at this
time.
HINT:
If the gears of the differential lock system are not meshed, the
indicator light remains blinking, so rotate the tires to mesh the
gear.
(4) When the Diff. lock control switch is at the OFF posi-
tion, the indicator light goes off.
Differential lock is released for the rear wheel at this
time.
(5) When the Diff. lock control switch is set to the FR/ RR position, the indicator lights (front side and rear
side) are turned on.
Differential lock is applied to both the front wheels
and rear wheels at this time.

(6) Check the voltage between the terminals of the Diff.
lock ECU when switching the Diff. lock control
switch with the speedometer, registering approx. 8
km/h (5 mph) or more.
(7) Check that the indicator lights blink when center Diff. lock release mode is set.
Diff. lock is released for both the front wheels and
rear wheels at this time.
(8) Return the Diff. lock control switch to OFF.
(9) Stop the engine and lower the vehicle.
2. INSPECT DIFF. LOCK SYSTEM CIRCUIT
(a) Inspect the system circuit with connector disconnected. Disconnect the connector from the Diff. lock ECU and in-
spect the connector on the wire harness side, as shown
in the chart.

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.

5. INSPECT DIFF. LOCK POSITION SWITCH
(a) Front and Rear:
Inspect the diff. lock position switch.
(1) Check that there is continuity between terminalswhen the switch is pushed (differential connected
position).
(2) Check that there is no continuity when the switch is
free (differential disconnected position).
If operation is not as specified, replace the switch.
(b) Inspect the center diff. indicator switch.
6. INSPECT VEHICLE SPEED SENSOR AND INDICATOR
