Measure the battery voltage between
input lead wires (O/W and B/W) at the
ECM with the ignition switch in the
"ON" position.
Correct
:
Measure the ignition coil primary peak
voltage. ( 10-20)
NOTE: The ignition coil peak voltage
inspection methotd is applicable only
with the multi circuit tester and the peak
volt adaptor.
Incorrect
:
Inspect the ignition coil/plug cap (-s).
