DIFFERENTIAL LOCK INDICATOR SWITCH CHECK
+Check switch function by checking continuity.
Continuity:
ON Continuity should exist.
OFF Continuity should not exist.
If NG, replace differential lock indicator switch.
DIFFERENTIAL LOCK SOLENOID CHECK
1. Disconnect differential lock solenoid 4-pin connector.
2. Check continuity between terminals
V1andV3,V2andV4.
Continuity should exist.
If NG, replace differential lock solenoid.
SPEED SENSOR CHECK
Refer to EL section.

DIFFERENTIAL LOCK CONTROL UNIT CHECK
On-vehicle check
Be sure that vehicle is in 4WD.
Operate vehicle at a speed less than 7 km/h (4 MPH) or
when stopping.
Turn differential lock switch ON.
Ensure differential lock indicator lamp is on.
Ye s
cNo
Malfunction is in system other than differential lock con-
trol unit, speed sensor. Check and correct.
Turn differential lock switch OFF while driving vehicle at
speed less than 7 km/h (4 MPH) or when stopping.
Drive vehicle at speed greater than 7 km/h (4 MPH) and
turn differential lock switch ON.
Ensure differential lock indicator lamp is on.
No
cYe s
When speed sensor functions, differential lock control
unit functions improperly.
Differential lock control unit is functioning properly.Check differential lock control unit.
Unit check
1. Ensure that wiring to differential lock control unit is correct and
that the unit is properly connected to power supply.
2. Place vehicle on a safety stand properly. Ensure that the front
and rear wheels rotate freely.
3. Check output voltage of differential lock at solenoid-2 connec-
tor.
+Vehicle speed less than 7 km/h (4 MPH) on speedometer
Power supply: Approximately 12V
+Vehicle speed greater than 7 km/h (4 MPH) on speedometer
Output voltage: Approximately 0V
