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 

EC-319, "Diagnosis Procedure"

.

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 

EC-319, "Diagnosis Procedure"

.

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 

EC-319, "Diagnosis Procedure"

.

Diagnosis Procedure

INFOID:0000000001671109
