Ignition Spark TestS6RW0D1804004
1) Remove air cleaner assembly with air intake pipe.
2) Disconnect all injector couplers from injectors.
WARNING!
Without disconnection of injector couplers,
combustible gas may come out from spark
plug holes during this test and may get
ignited in engine room.

3) Remove spark plug and check it for condition and
type referring to “Spark Plug Inspection”.
4) If OK, connect ignition coil coupler to ignition coil
assembly and connect spark plug to ignition coil
assembly or high-tension cord. Ground spark plug.5) Crank engine and check if each spark plug sparks.
6) If no spark is emitted, inspect the related parts as
described in “Ignition System Symptom Diagnosis”.

Spark Plug InspectionS6RW0D1806004
CAUTION!
• When servicing the iridium / platinum
spark plugs (slender center electrode type
plugs), do not touch the center electrode
to avoid damage to it. The electrode is not
strong enough against mechanical force
as it is slender and its material is not
mechanically tough.
• Do not clean or adjust gap for the iridium /
platinum spark plugs.

Inspect spark plug for:
• Electrode wear
• Carbon deposits
• Insulator damage
If any abnormality is found for nickel spark plugs, adjust
air gap, clean with spark plug cleaner or replace it with
specified new plug.
For iridium / platinum spark plugs, replace it with new
plug.
Spark plug air gap
“a”
: 1.0 – 1.1 mm (0.040 – 0.043 in.)
Spark plug type
NGK: BKR6E-11 (Nickel) / IFR6J11 (Iridium)
DENSO: K20PR-U11 (Nickel)
NOTE
NGK IFR6J11 is highly recommended for
better engine starting performance under –25
°C (–13 °F).

3) Ground “F” terminal and start engine, then measure
voltage at “B” terminal as shown in figure.
• Voltage is higher than standard value. It is
considered that generator itself is good but IC
regulator has been damaged, replace IC
regulator.
• Voltage is lower than standard value. It is
considered that generator itself has problem,
check the generator.
Load Check
1) Run engine at 2,000 rpm and turn on head light and
heater motor.
2) Measure current and if it is less than 20 A, repair or
replace generator.Generator Test (Overcharged Battery Check)S6RW0D1A04004
1) To determine battery condition, refer to “Battery
Description”.
2) If obvious overcharged condition exists as evidenced
by excessive spewing of electrolyte, measure
generator “B” terminal voltage at engine 2000 rpm.
3) If measured voltage is higher than upper limit value,
disassemble generator.
4) Check ground of brushes. If brushes are not
grounded, replace IC regulator. Then check field coil
for grounds and shorts.

With Auxiliary (Booster) Battery
CAUTION!
If vehicle is manual transaxle model and has
a catalytic converter, do not push or tow it to
start. Damage to its emission system and/or
to other parts may result.

Both booster and discharged battery should be treated
carefully when using jumper cables. Follow the
procedure outlined as follows, being careful not to cause
sparks.
WARNING!
• Departure from these conditions or
procedure described as follows could
result in:
– Serious personal injury (particularly to
eyes) or property damage from such
causes as battery explosion, battery
acid, or electrical burns.
– Damage to electronic components of
either vehicle.
• Remove rings, watches, and other jewelry.
Wear approved eye protection.
• Be careful so that metal tools or jumper
cables do not contact positive battery
terminal (or metal in contact with it) and
any other metal on vehicle, because a
short circuit could occur.
• Do not connect negative cable directly to
negative terminal of dead battery.
