IGNITION SYSTEM
EXCITER COIL PEAK VOLTAGE
Remove the ignition control module ( I C M ) (page 16-6).
Disconnect the ICM 4P and 2P connectors.
Connect the Imrie tester or peak voltage adaptor (+) probe to
the exciter coil (Black/Red) wire terminal of the 2P connector,
and the (-) probe to the body ground.
TOOL:
Imrie diagnostic lester (model 625) or
Peak voltage adapter 07HGJ - 0020100 with
Commercially available digital multimeter
(impedance 10 Mn/DCV minimum)
CONNECTION:
Black/Red terminal(•)- Body ground(-)
Crank the engine with the starter switch and read exciter coil
peak voltage.
PEAK VOLTAGE: 100 V minimum
To avoid possible electrfcal shock during voltage
measurements, do not touch test probe metal parts.
If the peak voltage measured at the ICM connector i s
abnormal, disconnect the exciter coil l i ne connector (Black/
Red) and connect lhe adaptor probes lo the exciter coil
terminal and body ground.
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 peak voltage measured at the I C M i s abnormal and
the one measured at the exciter coil i s normal. The wire
harness has an open circuit or loose connections.
If both peak voltages measure are abnormal, check each
i t em i n the troubleshooting chart. If all i t ems are normal,
the exciter coil is faulty.
