4. Attach one end of the remaining cable to the negative
terminal of the booster battery.
Attach the other end of the same cable to a solid
engine ground (such as the air conditioning
compressor bracket or the generator mounting
bracket) of the vehicle with the discharged battery.
The ground connection must be at least 450 mm (18
in.) from the battery of the vehicle whose battery is
being charged.

7. To remove the jumper cables, follow the above
directions in reverse order.
Be sure to first disconnect the negative cable from the
vehicle with the discharged battery.

Service Precaution
WARNING: IF SO EQUIPPED WITH 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
fastener 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 specifications. Following these
instructions can help you avoid damage to parts and
systems.

6D2–2
IGNITION SYSTEM
General Description
Ignition is done by the electronic ignition (El) that directly
fires the spark plugs from ignition coils through spark plug
wires without using a distributor. A pair of ignition coils for
the cylinders having different phases by 360
(No.1 and
No.4,No.2 and No.5,No.3 and No.6) are fired
simultaneously.
Since the cylinder on exhaust stroke requires less energy
to fire its ignition plug, energy from the ignition coils can be
utilized to fire the mating cylinder on compression stroke.
After additional 360
rotation, respective cylinder strokes
are reversed.
The EI consists of six ignition coils,ignition control
module, crank angle sensor, powertrain control module
(PCM) and other components.The ignition coils are connected with the PCM by means
of a 32 pin connector.
The ignition control module turns on/off the primary circuit
of ignition coils, and also it controls the ignition timing at
the engine speed below 538 rpm.
A notch in the timing disc on the crankshaft activates the
crank angle sensor which then sends information such as
firing order and starting timing of each ignition coil to the
PCM.
Further, the El employs ignition control (IC) to control
similar to a distributor system.
By receiving signals such as crank position,engine
speed, water temperature and Manifold Absolute
Pressure (MAP), the PCM controls the ignition timing.

Diagnosis
Refer to Section Drivability and Emissions for the
diagnosis to electronic ignition system (El system).

Spark Plug
Removal
1. Remove spark plugs.
Inspection and Repair
The spark plug affects entire engine performance and
therefore its inspection is very important.
Check electrode and insulator for presence of cracks,
and replace if any.
Check electrode for wear, and replace if necessary.
Check gasket for damage, and replace if necessary.
Measure insulation resistance with an ohmmeter, and
replace if faulty.
Adjust spark plug gap to 1.0 mm (0.04 in) 1.1 mm
(0.043 in).
Check fuel and electrical systems if spark plug is
extremely dirty.
Use spark plugs having low heat value (hot type plug)
if fuel and electrical systems are normal.
Use spark plugs having high heat value (cold type
plug) if insulator and electrode are extremely burned.
Sooty Spark Plugs
Much deposit of carbon or oil on the electrode and
insulator of spark plug reduces the engine performance.
Possible causes:
Too rich mixture
Presence of oil in combustion chamber
Incorrectly adjusted spark plug gap
Burning Electrodes
This fault is characterized by scorched or heavily oxidized
electrode or blistered insulator nose.
Possible causes:
Too lean mixture
Improper heat value
Measuring Insulation Resistance
Measure insulation resistance using a 500 volt
megaohm meter.
Replace spark plugs if measured value is out of
standard.
Insulation resistance: 50 M
or more
011RS010
Cleaning Spark Plugs
Clean spark plugs with a spark plug cleaner.
Raise the ground electrode to an angle of 45 to 60
degrees. If electrode is wet, dry it before cleaning.
After spark plug is thoroughly cleaned, check
insulator for presence of cracks.
Clean threads and metal body with a wire brush.
File the electrode tip if electrode is extremely worn.
Bend the ground electrode to adjust the spark plug
gap.
