System Diagram

System Description

INFOID:0000000009886100

The differential lock system consists of the following components

• Differential lock control unit

• Differential lock mode switch

• Differential lock position switch

• Differential lock solenoid

• ABS actuator and electric unit (control unit)

• Transfer control unit

DIFFERENTIAL LOCK SYSTEM OPERATION

When the differential lock mode switch is in the LOCK position, a signal is sent to the differential lock control

unit. The differential lock control unit monitors input from the ABS actuator and electric unit (vehicle speed and

VDC operation) and the transfer control unit (4WD shift switch). If conditions are set, the differential lock con-

trol unit provides power and ground to the differential lock solenoid to lock the differential. The differential lock

position switch provides feedback to the differential lock control unit as to whether the lock is engaged based

on pressure plate position. The differential lock control unit provides ground to the DIFF LOCK indicator lamp

to activate the lamp. Refer to the Owner’s Manual for differential lock system operating instructions.

As a fail-safe function, the differential lock disengages when a malfunction is detected in the differential lock

system. Self-diagnostics can be performed using CONSULT. Refer to 

DLN-214, "CONSULT Function (DIFF

LOCK)"
