General Repair Instruction
1. If a floor jack is used, the following precautions are
recommended.
Park vehicle on level ground, ªblockº front or rear
wheels, set jack against the recommended lifting
points (see ªLifting Instructionsº in this section), raise
vehicle and support with chassis stands and then
perform the service operations.
2. Before performing service operations, disconnect
ground cable from the battery to reduce the chance of
cable damage and burning due to short circuiting.
3. Use a cover on body, seats and floor to protect them
against damage and contamination.
4. Brake fluid and anti±freeze solution must be handled
with reasonable care, as they can cause paint
damage.
5. The use of proper tools and recommended essential
and available tools, where specified, is important for
efficient and reliable performance of service repairs.
6. Use genuine Isuzu parts.
7. Used cotter pins, plastic clips, gaskets, O±rings, oil
seals, lock washers and self±locking nuts should be
discarded and new ones should be installed, as
normal function of the parts cannot be maintained if
these parts are reused.
8. To facilitate proper and smooth reassembly
operation, keep disassembled parts neatly in groups.
Keeping fixing bolts and nuts separate is very
important, as they vary in hardness and design
depending on position of installation.
9. Clean the parts before inspection or reassembly. Also
clean oil ports, etc. using compressed air, and make
certain they are free from restrictions.
10. Lubricate rotating and sliding faces of the parts with
oil or grease before installation.
11. When necessary, use a sealer on gaskets to prevent
leakage.
12. Carefully observe all specifications for bolt and nut
torques.13. When removing or replacing parts that require
refrigerant to be discharged from the air conditioning
system, be sure to use the Vehicle Refrigerant
Recovery and Recycling Equipment (VRRRE) to
recover and recycle Refrigerant±134a.
14. When a service operation is completed, make a final
check to be sure the service has been done properly
and the problem has been corrected.
15. SUPPLEMENTAL RESTRAINT SYSTEM
The vehicle is equipped with a Supplemental
Restraint System (SRS) ± Air Bags. This system is
not to be serviced without consulting the appropriate
service information. Consult Section 9J ªSRS
Systemº if work is to be done on the front of the
vehicle such as bumper, sheet metal, seats, wiring,
steering wheel or column. Also review SRS system
information if any arc welding is to be done on the
vehicle. The SRS system equipped vehicle can be
identified by:
1. ªAIR BAGº warning light on the instrument
cluster.
2. A Code ªKº or ªMº for fifth digit of Vehicle
Identification Number.

6VE1 3.5L ENGINE DRIVEABILITY AND EMISSIONS
No Malfunction Indicator Lamp (MIL)
060R200049
Circuit Description
The ªCheck Engineº lamp (MIL) should always be
illuminated and steady with the ignition ªONº and the
engine stopped. Ignition feed voltage is supplied to the
MIL bulb through the meter fuse. The powertrain control
module (PCM) turns the MIL ªONº by grounding the MIL
driver circuit.
Diagnostic Aids
An intermittent MIL may be cased by a poor connection,
rubbed-through wire insulation, or a wire broken inside
the insulation. Check for the following items:
Inspect the PCM harness and connections for
improper mating, broken locks, improperly formed or
damaged terminals, poor terminal-to-wire
connection, and damaged harness.
If the engine runs OK, check for a faulty light bulb, an
open in the MIL driver circuit, or an open in the
instrument cluster ignition feed.
If the engine cranks but will not run, check for an open
PCM ignition or battery feed, or a poor PCM to engine
ground.
Test Description
Number(s) below refer to the step number(s) on the
Diagnostic Chart.
2. A ªNo MILº condition accompanied by a no-start
condition suggests a faulty PCM ignition feed or
battery feed circuit.
9. Using a test light connected to B+, probe each of the
PCM ground terminals to ensure that a good ground
is present. Refer to
PCM Terminal End View for
terminal locations of the PCM ground circuits.
12.In this step, temporarily substitute a known good
relay for the PCM relay. The horn relay is nearby,
and it can be verified as ªgoodº simply by honking
the horn. Replace the horn relay after completing
this step.
17.This vehicle is equipped with a PCM which utilizes
an electrically erasable programmable read only
memory (EEPROM). When the PCM is replaced,
the new PCM must be programmed. Refer to
PCM
Replacement and Programming Procedures
Powertrain Control Module (PCM) and Sensors.

Malfunction Indicator Lamp (MIL) ªONº Steady
060R200049
Circuit description
The malfunction indicator lamp (MIL) should always be
illuminated and steady with ignition ªONº and the engine
stopped. Ignition feed voltage is supplied directly to the
MIL indicator. The powertrain control module (PCM)
turns the MIL ªONº by grounding the MIL driver circuit.
The MIL should not remain ªONº with the engine running
and no DTC(s) set. A steady MIL with the engine running
and no DTC(s) suggests a short to ground in the MIL
driver circuit.
Diagnostic Aids
An intermittent may be caused by a poor connection,
rubbed-through wire insulation, or a wire broken inside
the insulation. Check for the following items:
Poor connection or damaged harness ± Inspect the
PCM harness and connectors for improper mating,
broken locks, improperly formed or damaged
terminals, poor terminal-to-wire connection, and
damaged harness.
Test Description
Number(s) below refer to the step number(s) on the
Diagnostic Chart.
2. If the MIL does not remain ªONº when the PCM is
disconnected, the MIL driver wiring is not faulty.
3. If the MIL driver circuit is OK, the instrument panel
cluster is faulty.
6. This vehicle is equipped with a PCM which utilizes
an electrically erasable programmable read only
memory (EEPROM). When the PCM is replaced,
the new PCM must be programmed. Refer to
