YES
>> INSPECTION END
NO
>> Proceed to
.
3.
CHECK IGNITION SIGNAL FUNCTION
Without CONSULT
1. Let engine idle.
2. Read the voltage signal between ECM harness connector terminals with an oscilloscope.
NOTE:
The pulse cycle changes depending on rpm at idle.
Is the inspection result normal?
YES
>> INSPECTION END
NO
>> Proceed to
