IGNITION SIGNAL FUNCTION
With CONSULT
1. Perform “POWER BALANCE” in “ACTIVE TEST” mode of “ENGINE” using CONSULT.
2. Check that each circuit produces a momentary engine speed drop.
Without CONSULT
1. Let engine idle.
2. Check the voltage signal between ECM harness connector and ground with an oscilloscope.
NOTE:
The pulse cycle changes depending on rpm at idle.
Is the inspection result normal?
YES
