Ignition Spark TestS7RS0B1804004
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”.

High-Tension Cord Removal and InstallationS7RS0B1806001
Removal
1) Remove air cleaner assembly with air intake pipe and cylinder head upper cover.
2) Disconnect No.1 cylinder (2) and No.3 cylinder (3)
high-tension cords from ignition coil assemblies (1)
while gripping each cap.
3) Pull out high-tension cords from spark plugs while gripping each cap.
CAUTION!
• Removal of high-tension cords together with clamps will be recommended so as
not to damage their inside wire (resistive
conductor).
• For the same reason, pull out each connection by gripping cap portion.

Installation
1) Install No.1 cylinder (2) and No.3 cylinder (3) high-
tension cords to spark plugs and ignition coil
assemblies (1) while gripping each cap.
CAUTION!
• Never attempt to use metal conductor high-tension cords as replacing parts.
• Insert each cap portion fully when installing high-tension cords.

Spark Plug InspectionS7RS0B1806004
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 them
with specified new plugs.
For iridium / platinum spark plugs, replace them with
new plugs.
Spark plug air gap
“a”
: 1.0 – 1.1 mm (0.040 – 0.043 in.)
Spark plug type
NGK: IFR6J11 (Iridium)
NOTE
NGK IFR6J11 is highly recommended for
better engine starting performance under –25
°C (–13 °F).
