DTC CONFIRMATION PROCEDURE
1.PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always perform the following procedure before conducting the next test.
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is more than 10.5 V with ignition switch ON.
>> GO TO 2.
2.PERFORM DTC CONFIRMATION PROCEDURE-1
If engine does not start, crank engine for at least 2 seconds.
Is 1st trip DTC detected? YES >> Proceed to EC-280, "Diagnosis Procedure".
NO >> GO TO 3.
3.PERFORM DTC CONFIRMATION PROCEDURE-2
Is 1st trip DTC detected? YES >> Proceed to EC-280, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis Procedure
1.CHECK STARTING SYSTEM
Turn ignition switch to START position.
Does the engine turn over? Does the starter motor operate? YES >> GO TO 2.
NO >> Check starting system. Refer to STR-20, "Work Flow (With GR8-1200 NI)" or STR-24, "Work Flow (Without GR8-1200 NI)".
2.CHECK CAMSHAFT POSITION (CMP) SENSOR (PHASE) POWER SUPPLY
Is the inspection result normal? YES >> GO TO 4.
NO >> GO TO 3.
3.CHECK SENSOR POWER SUPPLY 2 CIRCUIT
Check sensor power supply 2 circuit. Refer to EC-444, "Diagnosis Procedure".
Is inspection result normal? YES >> Perform the trouble diagnosis for power supply circuit.
NO >> Repair or replace error-detected parts.
4.CHECK CMP SENSOR (PHASE) GROUND CIRCUIT
Is the inspection result normal? YES >> GO TO 5.
NO >> Repair or replace error-detected parts.
5.CHECK CMP SENSOR (PHASE) INPUT SIGNAL CIRCUIT
Is the inspection result normal? YES >> GO TO 6.
NO >> Repair or replace error-detected parts.
6.CHECK CAMSHAFT POSITION SENSOR (PHASE)
Check the camshaft position sensor (PHASE). Refer to EC-282, "Component Inspection [CMP Sensor (PHASE)]".
Is the inspection result normal?
YES >> GO TO 7.
NO >> Replace camshaft position sensor (PHASE). Refer to EM-60, "Removal and Installation".
7.CHECK CAMSHAFT (INT)
Check the following.
Is the inspection result normal? YES >> Check intermittent incident. Refer to GI-39, "Intermittent Incident".
NO >> Remove debris and clean the signal plate of camshaft rear end or replace camshaft. Refer to EM-60, "Removal and Installation".
Component Inspection [CMP Sensor (PHASE)]
1.CHECK CAMSHAFT POSITION SENSOR (PHASE)-1
Is the inspection result normal? YES >> GO TO 2.
NO >> Replace camshaft position sensor (PHASE). Refer to EM-60, "Removal and Installation".
2.CHECK CAMSHAFT POSITION SENSOR (PHASE)-2
Check the resistance camshaft position sensor (PHASE) terminals as per the following.
Is the inspection result normal? YES >> INSPECTION END
NO >> Replace camshaft position sensor (PHASE). Refer to EM-60, "Removal and Installation".
