IGNITION SIGNAL
Description
INFOID:0000000001671107
The ignition signal from the ECM is sent to and amplified by the power transistor. The power transistor turns
ON and OFF the ignition coil primary circuit. This ON/OFF operation induces the proper high voltage in the coil
secondary circuit.
Component Function Check
INFOID:0000000001671108
1.
INSPECTION START
Turn ignition switch OFF, and restart engine.
Does the engine start?
YES-1 >> With CONSULT-III: GO TO 2.
YES-2 >> Without CONSULT-III: GO TO 3.
NO
>> Go to
2.
IGNITION SIGNAL FUNCTION
With CONSULT-III
1.
Perform “POWER BALANCE” in “ACTIVE TEST” mode with CONSULT-III.
2.
Make sure that each circuit produces a momentary engine speed drop.
Is the inspection result normal?
YES
>> INSPECTION END
NO
>> Go to
3.
IGNITION SIGNAL FUNCTION
Without CONSULT-III
1.
Let engine idle.
2.
Read the voltage signal between ECM harness connector terminals as follows.
NOTE:
The pulse cycle changes depending on rpm at idle.
Is the inspection result normal?
YES
>> INSPECTION END
NO
>> Go to
