Is the inspection result normal? YES >> GO TO 9.
NO >> Repair or replace. Then GO TO 4
9.CHECK ECM FUNCTION
1. Substitute another known-good ECM to check ECM function. (ECM may be the
cause of an incident, but
this is a rare case.)
2. Perform initialization of NATS system and registration of all NATS ignition
key IDs. Refer to SEC-50,
"ECM : Work Procedure".
>> GO TO 4.
10.CHECK IGNITION TIMING
1. Run engine at idle.
2. Check ignition timing with a timing light.
For procedure, refer to EC-444, "Special Repair Requirement" For specification, refer to EC-449, "Ignition Timing".
1 : Timing indicator
Is the inspection result normal? YES >> INSPECTION END.
NO >> GO TO 11.
11.PERFORM ACCELERATOR PEDAL RELEASED POSITION LEARNING
1. Stop engine.
2. Perform EC-134, "Work Procedure".
>> GO TO 12.
12.PERFORM THROTTLE VALVE CLOSED POSITION LEARNING
12.PERFORM THROTTLE VALVE CLOSED POSITION LEARNING Perform EC-135, "Work Procedure".
>> GO TO 13.
13.PERFORM IDLE AIR VOLUME LEARNING
Perform EC-136, "Work Procedure".
Is Idle Air Volume Learning carried out successfully? YES >> GO TO 14.
NO >> Follow the instruction of Idle Air Volume Learning. Then GO TO 4.
14.CHECK TARGET IDLE SPEED AGAIN
1. Start engine and warm it up to normal operating temperature.
2. Check idle speed.
For procedure, refer to EC-443, "Special Repair Requirement".
For specification, refer to EC-449, "Idle Speed".
Is the inspection result normal? YES >> GO TO 15.
NO >> GO TO 17.
15.CHECK IGNITION TIMING AGAIN
