Service Precaution
WARNING: THIS VEHICLE HAS A SUPPLEMENTAL
RESTRAINT SYSTEM (SRS). REFER TO THE SRS
COMPONENT AND WIRING LOCATION VIEW IN
ORDER TO DETERMINE WHETHER YOU ARE
PERFORMING SERVICE ON OR NEAR THE SRS
COMPONENTS OR THE SRS WIRING. WHEN YOU
ARE PERFORMING SERVICE ON OR NEAR THE
SRS COMPONENTS OR THE SRS WIRING, REFER
TO THE SRS SERVICE INFORMATION. FAILURE
TO FOLLOW WARNINGS COULD RESULT IN
POSSIBLE AIR BAG DEPLOYMENT, PERSONAL
INJURY, OR OTHERWISE UNNEEDED SRS
SYSTEM REPAIRS.CAUTION: Always use the correct fastener in the
proper location. When you replace a fastener, use
ONLY the exact part number for that application.
ISUZU will call out those fasteners that require a
replacement after removal. ISUZU will also call out
the fasteners that require thread lockers or thread
sealant. UNLESS OTHERWISE SPECIFIED, do not
use supplemental coatings (Paints, greases, or
other corrosion inhibitors) on threaded fasteners
or fasteners joint interfaces. Generally, such
coatings adversely affect the fastener torque and
the joint clamping force, and may damage the
fastener. When you install fasteners, use the
correct tightening sequence and specification.
Following these instructions can help you avoid
damage to parts and systems.

DRIVE LINE CONTROL SYSTEM (SHIFT ON THE FLY)
Warning at “4L” position :In view of the shifting
mechanism of transfer, the gear shifting from 4WD to
2WD at “4L” condition is impossible. Therefore, the
transfer position switch can not be turned off by 4WDswitch when vehicle is in “4L” condition. In the case this
condition continues for 2 seconds, the shifting to 2WD is
stopped and the indicator lamp’s blinking changes from
2Hz to 4Hz to notify driver of wrong operation.

Diagnosis from Symptom
Troubles that are not indicated by the warning lamp are
listed in the table below. These troubles are caused by
the faults that cannot be detected by the self-diagnostic
function of the control unit.
If this type of trouble is observed, interview the customer
and conduct test runs to reproduce the trouble,cross-check the reported trouble with the listed
phenomena, and diagnose and analyze the trouble on the
item by item basis.
PhenomenaMajor causeCorrective action
1The tight corner braking is ob-
served when the vehicle is subject
to full steering.The standard tires are not used.
The tire pressure is incorrect.
The tires are worn inuniformity.
The transfer or wiring is
imperfect.
The limited slip differential is
failed.
Check and recondition the ve-
hicle according to Chart 1.
2Even if the 4WD SW is select to the
4WD position, the 4WD mode is not
active, resulting in remarkable rear
wheel spin.The transfer or wiring is
imperfect.
The shift on the fly system is
failed.
Check and recondition the ve-
hicle according to Chart 2.
3When the 4WD SW is select to
the 4WD position, the drive
resistance of the 4WD system is
too large to get sufficient running
speed.
Noised drive line.
The standard tires are not used.
The tire pressure is incorrect.
The tires are worn inuniformity.
The transfer or wiring is
imperfect.
The limited slip differential is
Check and recondition the ve-
hicle according to Chart 1.
4The shift on the fly system (front
axle) generates gear noises.The wiring is imperfect.
The full automatic free wheel
hub is failed.
Check and recondition the ve-
hicle according to Chart 3.
5The braking distance gets long
even when the ABS is active.The wiring is imperfect.
The ABS is failed.
Check and recondition the ve-
hicle according to Chart 4.
