IGNITION PULSE GENERATOR PEAK VOLTAGE
NOTE:
Check that the cylinder compression is normal and the spark
plug i s i n stalled correctly i n the cylinder head.
Disconnect the ignition control module (ICM) connector (page
16-6).
Connect the peak voltage adaptor (+) probe to the ignition
pulse generator (blue/yellow)
wire terminal of the 4P
connector, and the (-) probe to the body ground.
CONNECTION:
Blue/Yellow wire terminal(+) - Body ground(-)
Turn lhe i g nition swilch ON.
Crank the engine with the starter switch and read the peak
voltage.
PEAK VOLTAGE: 0.7 V minimum
If the peak voltage measured at the ICM connector is abnor-
mal, disconnect the ignition pulse generator connector and
connect the adaptor probles to the ignition pulse generator
side connector.
In the same manner as the I C M connector, measure the peak
voltage and compare i t to the voltage measured at the I C M
connector.
I f the peak vollage measured at the I C M connector i s
abnomal and the one measured at the i g nition pulse
generator connector i s normal, the blue/yellow wire has
an open or short circuit, or loose connections.
I f both peak voltages are abnormal, follow the checks de-
scribed i n the troubleshooting on page 16-2.
IGNITION TIMING
li i {khUl l d N
When the engine must be running to do some work, make
sure the area is well ventilated. Never run the engine in a
closed area. The exhaust contains poisonous carbon monox-
ide gas that may cause loss of consciousness and lead to
death. Run the engine in an open area or with an exhaust
evacuation system In an enclosed area.
Warm up the engine to the normal operating temperature.
Remove the timing hole cap (page 3-8).
Connect the timing light and a tachometer.
NOTE:
Read the manufacturer's i n structions for the timing light and
tachometer.
