•
Check
cylinder
compression end check
that
the spark
plugs are
installed correctly.
Remove
the fuel
tank
(page

Remove
the ignition control
module
(ICM)
and
disconnect
rhe
4
P connector from
the
ICM.
Connect
the peak
voltage adapter or Imrie
tester
probes
to
the
cormoctor
torminola of tho ignition
puleo generator
side.

•
A
void touching
the spark plugs
and
tester
probes
to
prevent
elec-
tric
shock.
If
the
peak
voltage
measured
at
the
ICM
connector
is
abnor-
mal, disconnect the
ignition
pulse generator
2P
(White! con-
nector
and connect
the
tester
probes
to the terminal (Blue/
Yellow and
Green/White).
In the
same manner
as at the
ICM
connector,
measure
the
peak voltage and
compare
it
to the voltage
measured
at
the
ICM
connector.
•
If
the poak
voltage
measured
at
the
ICM
is
abnormal and
the
one measured
at
the
ignition
pulse generator
is
normal,
the wire harness
has an open
circuit
or loose connection.
•
If
both peak voltages
measure
are
abnormal, check each
item
in
the troubleshooting
chart.
If all
items
are
normal,
the ignition pulse
generator
is
faulty.
See
section 10
for
ignition
pulse generator replacement.
