SERVICE DATA AND SPECIFICATIONS (SDS)

System Description
The differential lock operates only in 4WD.
The differential lock control unit interrupts current ¯owing through
differential lock solenoid-2 when vehicle speed exceeds 7 km/h (4
MPH). If the differential lock switch is accidentally turned on when
vehicle speed is greater than 7 km/h (4 MPH), the control unit will
prevent the differential lock from sustaining impact damage.
A warning buzzer will sound when the vehicle is driven over 20
km/h (12 MPH) with the differential lock engaged.

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.
