P1848 SOLENOID DISCONNECT

Description

INFOID:0000000005275612

When power and ground is supplied from the differential lock control unit, the differential lock solenoid will
actuate to move the pressure plate against the cam ring to lock the differential. By reversing polarity at the dif-
ferential lock control unit, the differential lock solenoid moves the pressure plate away from the cam ring to
unlock the differential.

Diagnosis Procedure

INFOID:0000000005275614

Regarding Wiring Diagram information, refer to 

DLN-296, "Wiring Diagram"

.

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.

3.

CHECK DIFFERENTIAL LOCK SOLENOID OPERATION

Check operation by applying power and ground to the differential
lock solenoid terminals.

Is the inspection result normal?

YES

>> GO TO 4.

NO

>> Check for a mechanical malfunction with the differential

lock system. Replace differential solenoid.

4.

CHECK DIFFERENTIAL LOCK SOLENOID CIRCUIT

1.

Disconnect differential lock control unit harness connector.

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"

.
