2.
Check continuity between differential lock control unit harness
connector M70 (A) terminals 11, 12 and differential lock solenoid
harness connector C117 (B) terminals 4, 2.
3.
Check continuity between differential lock control unit harness
connector M70 (A) terminals 11, 12 and ground.
Is the inspection result normal?
YES
>> Replace the differential lock control unit. Refer to
DLN-310, "Removal and Installation"
.
NG
>> Repair harness or connector.

INFOID:0000000005275619
Diagnosis Procedure
INFOID:0000000005275620
Regarding Wiring Diagram information, refer to
1.
CHECK DIFFERENTIAL SOLENOID CONTROL
1.
Start engine.
2.
Using CONSULT-III, select “RELAY ON”, “RELAY MTR”, “SOL MTR” of DIFF LOCK data monitor.
3.
Observe the display values while operating the differential lock system.
Is the inspection result normal?
YES
>> Differential lock solenoid control system is operating normally.
NO
>> GO TO 2.
2.
CHECK DIFFERENTIAL LOCK SOLENOID RESISTANCE
1.
Turn ignition switch OFF.
2.
Disconnect differential lock solenoid harness connector C117.
3.
Check resistance between differential lock solenoid terminals 2
and 4.
Is the inspection result normal?
YES
>> GO TO 3.
NO
>> Replace differential solenoid.

C1203 ABS SYSTEM
Description
INFOID:0000000005275621
The differential lock control unit and the ABS actuator and electric unit (control unit) are in communication via
the CAN communication network. Vehicle speed and wheel slippage information is used by the differential lock
control unit to determine if conditions are met to actuate the differential lock solenoid.
