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 TOFOLLOW WARNINGS COULD RESULT IN POSSIBLEAIR BAG DEPLOYMENT, PERSONAL INJURY, OROTHERWISE 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 threade d fasteners or
fasteners joint interfaces. Generally, such coatings
adversely affect the fastener torque and the joint
clamping force, and may damage the fasteners.
When you install fasteners, use the correct
tightening sequence and specifications. Following
these instructions can help you avoid damage to
parts and systems.

Key Coding
730RX001
Legend
EndOFCallout
One key is used for the ignition, door, and tailgate lock
cylinders. The ke ys are cut on both edges to make them
reversible.
Key identification is obtained from the five character ke y
code stamped on the key code tag. From this key code,
the ke y code cutting combination can be determined
from a code list (available to owners of key cutting
equipment from suppliers).
If key codes are not available from records or tags, the
key code can be obtained from the right hand door lock
cylinder (if lock has not been replaced). Lock cylinders
supplied by the factory as service parts are unmarked.
If the original key is availab l e, the key code cutting
combination can be determined by la ying the ke y on the
diagram shown in the figure.
Key Styles

The keys come in styles A or B depending on the key
code cutting combination. When the first position in the
combination is a 1, 2 or 3, Style A is used. When the
first position is a 4, Style B (factory pre-cut key) is us ed.

Power Door Lock System
General Description
The circuit consists of the door lock (& power window)
switch, door lock actuator for the front and rear door,
tailgate lock actuator, fuel filler door lock actuator and
the door lock key switch.
The front door lock switch–LH is always provided with
the battery voltage.
The key or the inside lock button on the both driver's
and the front passenger's door can activate the lock
mechanism of all the doors (including the tailgate).
When the driver's door lock switch or the front
passenger's door lock switch is turned on, current flows
for about one second to the door lock actuator of each
door connected in parallel with the front door lock (&
power window) switch–LH to activate the actuator to
lock and unlock the doors.
