• During cranking or idling, check waveforms between terminal IGT and E1 of engine control module.
HINT: The correct rectangular waveforms are as shown.

NG                    OK  Replace igniter.

9  Check for open and short in harness and connector in IGT signal circuit between engine control module and igniter (See page IN-30).

OK                    NG  Repair or replace harness or connector.
