1.PRECONDITIONING
Make sure that all of the following conditions are satisfied.
Learning will be cancelled if any of the following conditions are missed for even a moment.

NO >> GO TO 3.
2.IDLE AIR VOLUME LEARNING
With CONSULT
Is “CMPLT” displayed on CONSULT screen? YES >> GO TO 4.
NO >> GO TO 5.
3.IDLE AIR VOLUME LEARNING
Without CONSULT
NOTE:
>> GO TO 4
4.CHECK IDLE SPEED AND IGNITION TIMING
Rev up the engine two or three times and make sure that idle speed and ignition timing are within the specifications.
For specification, refer to EC-500, "Idle Speed" and EC-500, "Ignition Timing".
Is the inspection result normal? YES >> INSPECTION END

It is useful to perform “TROUBLE DIAGNOSIS - SPECIFICATION VALUE”. Refer to EC-157, "Description".
If any of the following conditions occur after the engine has started, eliminate the cause of the incident and perform Idle Air Volume Learning all over again:
