Component Function Check
1.INSPECTION START
Turn ignition switch OFF, and restart engine.
Does the engine start? YES-1 >> With CONSULT: GO TO 2.
YES-2 >> Without CONSULT: GO TO 3.
NO >> Proceed to EC-470, "Diagnosis Procedure".
2.CHECK IGNITION SIGNAL FUNCTION
With CONSULT
Is the inspection result normal? YES >> INSPECTION END
NO >> Proceed to EC-470, "Diagnosis Procedure".
3.CHECK IGNITION SIGNAL FUNCTION
Without CONSULT
NOTE: The pulse cycle changes depending on rpm at idle. Is the inspection result normal? YES >> INSPECTION END
NO >> Proceed to EC-470, "Diagnosis Procedure".
Diagnosis Procedure
1.CHECK ECM POWER SUPPLY
Is the inspection result normal? YES >> GO TO 2.
NO >> Refer to EC-165, "Diagnosis Procedure".
2.CHECK CONDENSER POWER SUPPLY
Is the inspection result normal? YES >> GO TO 4.
NO >> GO TO 3.
3.CHECK CONDENSER POWER SUPPLY CIRCUIT
Also check harness for short to ground and to power.
Is the inspection result normal? YES >> Refer to EC-165, "Diagnosis Procedure".
NO >> Repair open circuit, short to ground or short to power in harness or connectors.
4.CHECK CONDENSER GROUND CIRCUIT
Is the inspection result normal? YES >> GO TO 5.
NO >> Repair open circuit or short to power in harness or connectors.
5.CHECK CONDENSER
Check condenser. Refer to EC-474, "Component Inspection (Condenser)" Is the inspection result normal? YES >> GO TO 6.
NO >> Replace condenser.
6.CHECK IGNITION COIL POWER SUPPLY
Is the inspection result normal? YES >> GO TO 7.
NO >> Repair or replace harness or connectors.
7.CHECK IGNITION COIL GROUND CIRCUIT
Is the inspection result normal? YES >> GO TO 8.
NO >> Repair open circuit or short to power in harness or connectors.
8.CHECK IGNITION COIL OUTPUT SIGNAL CIRCUIT
Is the inspection result normal? YES >> GO TO 9.
NO >> Repair open circuit, short to ground or short to power in harness or connectors.
9.CHECK IGNITION COIL WITH POWER TRANSISTOR
Check ignition coil with power transistor. Refer to EC-473, "Component Inspection (Ignition Coil with Power Transistor)".
Is the inspection result normal? YES >> Check intermittent incident. Refer to GI-41, "Intermittent Incident".
NO >> Replace malfunctioning ignition coil with power transistor. Refer to EM-36, "Removal and Installation".
Component Inspection (Ignition Coil with Power Transistor)
1.CHECK IGNITION COIL WITH POWER TRANSISTOR-1
Is the inspection result normal? YES >> GO TO 2.
NO >> Replace malfunctioning ignition coil with power transistor. Refer to EM-36, "Removal and Installation".
2.CHECK IGNITION COIL WITH POWER TRANSISTOR-2
CAUTION: Perform the following procedure in a place with no combustible objects and good ventilation.
NOTE: Do not use CONSULT to release fuel pressure, or fuel pressure applies again during the following procedure.
Spark should be generated.
CAUTION:
NOTE: When the gap is less than 13 mm (0.52 in), the spark might be generated even if the coil is malfunctioning. Is the inspection result normal? YES >> INSPECTION END
NO >> Replace malfunctioning ignition coil with power transistor. Refer to EM-36, "Removal and Installation".
Component Inspection (Condenser)
1.CHECK CONDENSER
Is the inspection result normal? YES >> INSPECTION END
NO >> Replace condenser.
