(2) Removal of resistive cords and ignition coils
q Disconnect the resistive cord from the ignition coil.
w Remove the No. 1 and No. 3 resistive cords by dis-
connecting the connectors from the ignition coils
and spark plugs.
CAUTION:
·
Never disconnect the resistive cords by holding the
cord section of the resistive cords.
e Disconnect the connectors from the ignition coils.
r Remove the ignition coils on the spark plugs of
No. 2 and No. 4 cylinders by removing the attach-
ing nuts.
(3) Measurement of insulation resistance
Measure the insulation resistance of each spark plug,
using a megger (Insulation resistance meter) and en-
sure that the measured insulation resistance of each
spark plug is more than the specified value.
Minimum Insulation Resistance:
If the measured insulation resistance is less than
15 MW proceed to the step (4) onward.
If the measured insulation resistance is more than the
specified value, proceed to the step (4) onward except
the step (8).
When a megger is not available:
q Start the engine. Warm up the engine completely.
w Race the engine at 4000 rpm for five seconds.
e Stop the engine.
r Remove the air cleaner.(Refer to the removal of the
air cleaner.)
t Remove the resistive cords and ignition coils.
(Refer to the check and adjustment of the valve
clearance section for the removal of the ignition
coil and resistive cord.)
y Remove the spark plug, using a suitable spark
plug wrench or the following SST.
SST: 09268-87703-000
WARNING:
·
Be very careful not to get scalded with hot spark plugs,
since spark plugs are hot.
u Visually inspect the spark plug.
If the electrode is dry: Proceed to the step (6)
(Satisfactory)
If the electrode is wet: Proceed to the step (5).
