Idle Air Volume LearningNCEC0541DESCRIPTIONNCEC0541S01ªIdle Air Volume Learningº is an operation to learn the idle air vol-
ume that keeps each engine within the specific range. It must be
performed under any of the following conditions:
IEach time IACV-AAC valve, throttle body or ECM is replaced.
IIdle speed or ignition timing is out of specification.
PRE-CONDITIONINGNCEC0541S04Before performing ªIdle Air Volume Learningº, 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.
IBattery voltage: More than 12.9V (At idle)
IEngine coolant temperature: 70 - 94ÉC (158 - 201ÉF)
IPNP switch: ON
IElectric load switch: OFF
(Air conditioner, headlamp, rear window defogger)
On vehicles equipped with daytime running light systems, set
lighting switch to the 1st position to light only small lamps.
ICooling fan motor: Not operating
ISteering wheel: Neutral (Straight-ahead position)
IVehicle speed: Stopped
ITransmission : Warmed up
For CVT models with CONSULT-II, drive vehicle until ªFLUID
TEMP SEº in ªDATA MONITORº mode of ªCVTº system indi-
cates less than 0.9V.
For CVT models without CONSULT-II and M/T models, drive
vehicle for 10 minutes.
OPERATION PROCEDURENCEC0541S02With CONSULT-IINCEC0541S02011. Start engine and warm it up to normal operating temperature.
2. Check that all items listed under the topic ªPre-Conditioningº
(previously mentioned) are in good order.
3. Turn ignition switch ªOFFº and wait at least 9 seconds.
4. Start the engine and allow it to idle for at least 28 seconds.
5. Select ªIDLE AIR VOL LEARNº in ªWORK SUPPORTº mode.
6. Touch ªSTARTº and wait 20 seconds.
7. Make sure that ªCMPLTº is displayed on CONSULT-II screen.
If ªINCMPº is displayed, ªIdle Air Volume Learningº will not be
carried out successfully. In this case, find the cause of the
problem by referring to the NOTE below.
8. Rev up the engine two or three times. Make sure that idle
speed and ignition timing are within specifications.

Basic InspectionNCEC0038Precaution:
Perform Basic Inspection without electrical or mechanical loads applied;
IHeadlamp switch is OFF,
IOn vehicles equipped with daytime running light systems, set lighting switch to the 1st position to light only
small lamps.
IAir conditioner switch is OFF,
IRear window defogger switch is OFF,
ISteering wheel is in the straight-ahead position, etc.
1 INSPECTION START
1. Check service records for any recent repairs that may indicate a related problem, or the current need for scheduled maintenance.
2. Open engine hood and check the following:
IHarness connectors for improper connections
IVacuum hoses for splits, kinks, or improper connections
IWiring for improper connections, pinches, or cuts
IAir cleaner clogging
IHoses and ducts for leaks
