Isuzu D-Max / Isuzu Rodeo (TFR/TFS). Manual - part 1709

ENGINE ELECTRICAL  6D1-5

Battery fluid is a highly corrosive acid.
Should battery fluid come in contact with your eyes, skin, fabric,
or a painted surface, immediately and thoroughly rinse the
affected area with clean tap water.
Never allow metal tools or jumper cables to come in contact
with the positive battery terminal, or any other metal surface of
the vahicle. This will protect against a short circuit.
Always keep batteries out of reach of young children.

Jump Starting Procedure

1. Set the vehicle parking brake.

If  the  vahicle  is  equipped  with  an  automatic  transmission,

place the selector level in the "PARK" position.

If the vehicle is equipped with a manual transmission, place

the shift lever in the "NEUTRAL" position.

Turn "OFF" the ignition.

Turn  "OFF"  all  lights  and  any  other  accessory  requiring

electrical power.

2. Look at the built-in hydrometer.

If the indication area of the built-in hydrometer is completely

clear, do not try to jump start.

3. Attach the end of one jumper cable to the positive terminal

of the booster battery.

Attach  the  other  end  of  the  same  cable  to  the  positive

terminal of the discharged battery.

Do  not  allow  the  vehicles  to  touch  each  other.  This  will

cause  a  ground  connection,  effectively  neutralizing  the

charging procedure.

Be sure that the booster battery has a 12 volt rating.

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.

WARNING: NEVER ATTACH THE END OF THE JUMPER
CABLE DIRECTLY TO THE NEGATIVE TERMINAL OF THE
DEAD BATTERY.
5. Start the engine of the vehicle with the good battery.

Make sure that all unnecessary electrical accessories have

been turned "OFF".

6. Start the engine of the vehicle with the dead battery.

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.

6D2-2  IGNITION SYSTEM

General Description

Ignition is done by the Ignition Module that fires.
Since the cylinder on exhaust stroke requires less energy to
fire its spark plug, energy from the ignition coils can be utilized
to fire the mating cylinder on compression stroke.
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 ignition coil to the ECM.
By receiving signals such as crank position, engine speed,
water temperature and Manifold Absolute Pressure (MAP), the
ECM controls the ignition timing.

Service Precaution

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.

Diagnosis

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