NOTE:
.
lf
there
is
no spark at the plug, check all connections
for
loose
or
poor contact before
measuring
each
peak voltage.
.
Use
a
commercially available digital
multimeter with
an impedance of
10 MO/DCV minimum.
.
The
display value differs
depending upon
the
internal impedance of
the
multimeter.
.
lf
the peak voltage
tester (U.S.A. only) is
used,
follow the manufacturer's
instructions.
Use the peak voltage tester or connect the peak voltage
adaptor
[1]
to the digital multimeter
[2].

NOTE:
.
Check the cylinder compression and check that
the
spark plugs are
installed correcily in the
cylinder
head.
Disconnect the direct
ignition coil 3P (Black)
connector
(page 3-6).
Disconnect the fuel pump
3P (Black) connector
when
the front cylinder side inspection is performed
(page 7-
5).
Connect the peak voltage tester or adaptor [1] probes to

NOTE:
.
Although
measured values are different for
each
ignition coil
connector,
they are
normal as
long
as
voltage is higher than the specifled value.
lf the peak voltage
is
lower
than the standard
value,
follow the
checks described
In the troubleshooting table
(page 5-5).
