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-783, "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-783, "Diagnosis Procedure"

.

3.

IGNITION SIGNAL FUNCTION

 Without CONSULT-III

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

>> Go to 

EC-783, "Diagnosis Procedure"

.

Diagnosis Procedure

INFOID:0000000006496443

1.

CHECK IGNITION COIL POWER SUPPLY CIRCUIT-I

1.

Turn ignition switch OFF, wait at least 10 seconds and then turn ON.

2.

Check the voltage between ECM harness connector and ground.

Is the inspection result normal?

YES

>> GO TO 2.

NO

CHECK IGNITION COIL POWER SUPPLY CIRCUIT-II

1.

Turn ignition switch OFF.

2.

Disconnect condenser harness connector.

3.

Turn ignition switch ON.

4.

Check the voltage between condenser harness connector and ground.

Is the inspection result normal?

YES

>> GO TO 5.

NO

>> GO TO 3.

3.

CHECK IGNITION COIL POWER SUPPLY CIRCUIT-III

1.

Turn ignition switch OFF.

2.

Disconnect IPDM E/R harness connector E15.

3.

Check the continuity between IPDM E/R harness connector and condenser harness connector.

4.

Also check harness for short to ground and short to power.

Is the inspection result normal?

YES

>> GO TO 11.

NO

>> GO TO 4.

4.

DETECT MALFUNCTIONING PART

Check the following.
• Harness connectors E8, F1
• Harness for open or short between IPDM E/R and condenser

>> Repair open circuit or short to ground or short to power in harness or connectors.

5.

CHECK CONDENSER GROUND CIRCUIT FOR OPEN AND SHORT

1.

Turn ignition switch OFF.

2.

Check the continuity between condenser harness connector and ground.

3.

Also check harness for short to power.

Is the inspection result normal?

YES

>> GO TO 6.

NO

>> Repair open circuit or short to ground or short to power in harness or connectors.

6.

CHECK CONDENSER

Refer to 

EC-787, "Component Inspection (Condenser)"

Is the inspection result normal?

YES

>> GO TO 7.

NO

>> Replace condenser.

7.
