1.

INSPECTION START

Turn ignition switch OFF, and restart engine.
Does the engine start?

YES

>> GO TO 2.

NO

>> Proceed to 

EC-554, "Diagnosis Procedure"

.

2.

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

>> INSPECTION END

NO

>> Proceed to 

EC-554, "Diagnosis Procedure"

.

Diagnosis Procedure

INFOID:0000000012198099

5.

CHECK IGNITION COIL POWER SUPPLY

1. Reconnect all harness connectors disconnected.

2. Disconnect ignition coil harness connector.

3. Turn ignition switch ON.

4. Check the voltage between ignition coil harness connector and ground.

Is the inspection result normal?

YES

>> GO TO 6.

NO

>> Perform the trouble diagnosis for power supply circuit.

6.

CHECK IGNITION COIL GROUND CIRCUIT

1. Turn ignition switch OFF.
