.
Ignition Coil Primary Peak Voltage
1) Remove the right side cover and right inner fender.
Refer to
“Front Side Exterior Parts Removal and
Installation: in Section 9D”
.
2) Disconnect the spark plug cap. Refer to “Spark Plug
Cap and Spark Plug Removal and Installation
(Page 1H-3)”.
3) Connect the new spark plug to spark plug cap and
ground it to the cylinder head.
NOTE
Be sure that the spark plug is connected
properly and the battery used is in fully-
charged condition.
4) Connect the multi-circuit tester with the peak voltage
adaptor as follows:
CAUTION
!
Before using the multi-circuit tester and peak
voltage adaptor, refer to the appropriate
instruction manual.
NOTE
Do not disconnect the ignition coil lead
wires.
Special tool
(A): 09900–25008 (Multi-circuit tester set)
Tester knob indication: Voltage (
)
5) Measure the ignition coil primary peak voltage in the
following procedures:
a) Shift the transfer to the neutral, turn the ignition
switch ON.
b) Press the starter button and allow the engine to
crank for a few seconds, and then measure the
ignition coil primary peak voltage.
6) Repeat the b) procedure few times and measure the
highest peak voltage.
If the voltage is lower than standard range, inspect
the ignition coil and the CKP sensor.
Ignition coil primary peak voltage
80 V and more
7) After measuring the ignition coil primary peak
voltage, reinstall the removed parts.
