IDLE AIR VOLUME LEARNING
IDLE AIR VOLUME LEARNING
DescriptionINFOID:0000000012431358
Idle Air Volume Learning is a function of ECM to learn the idle air volume that keeps each engine idle speed
within the specific range. It must be performed under any of the following conditions:
• Each time electric throttle control actuator or ECM is replaced.
• Idle speed or ignition timing is out of specification.
Refer to
EC-130, "
Work Procedure".
Work ProcedureINFOID:0000000012431359
1.PRECONDITIONING
Make sure that all of the following conditions are satisfied.
Learning will be cancelled if any of the follo wing conditions are missed for even a moment.
• Battery voltage: More than 12.9 V (At idle)
• Engine coolant temperature: 70 - 100 °C (158 - 212° F)
• Selector lever: P or N (CVT), Neutral (M/T)
• Electric load switch: OFF
(Air conditioner, headlamp, rear window defogger)
- For vehicles equipped with dayt ime light systems, perform one of the following procedures before
starting engine not to illuminate headlamps.
• Apply parking brake
• Set lighting switch to the 1st position
• Steering wheel: Neutral (Straight-ahead position) position
• Vehicle speed: Stopped
• Transmission: Warmed-up
- CVT models
• With CONSULT: Drive vehicle until “FLUID TEMP SE ” in “DATA MONITOR” mode of “TRANSMISSION” sys-
tem indicates less than 0.9 V.
• Without CONSULT: Drive vehicle for 10 minutes.
- M/T models
• Drive vehicle for 10 minutes.
Do you have CONSULT?
YES >> GO TO 2.
NO >> GO TO 3.
2.IDLE AIR VOLUME LEARNING
With CONSULT
1. Perform ACCELERATOR PEDAL RELEAS ED POSITION LEARNING. Refer to EC-128, "
Description".
2. Perform THROTTLE VALVE CLOSED POSITION LEARNING. Refer to EC-129, "
Description".
3. Start engine and warm it up to normal operating temperature.
4. Select “IDLE AIR VOL LEARN” in “WORK SUPPORT” mode with CONSULT.
5. Touch “START” and wait 20 seconds.
Is
“CMPLT” displayed on CONSULT screen?
YES >> GO TO 4.
NO >> GO TO 5.
3.IDLE AIR VOLUME LEARNING
Without CONSULT
NOTE:
• It is better to count the ti me accurately with a clock.
• It is impossible to switch the di agnostic mode when an accelerator pedal position sensor circuit has
a malfunction.
1. Perform ACCELERATOR PEDAL RELEAS ED POSITION LEARNING. Refer to EC-128, "
Description".
2. Perform THROTTLE VALVE CLOSED POSITION LEARNING. Refer to EC-129, "
Description".
3. Start engine and warm it up to normal operating temperature.
4. Turn ignition switch OFF and wait at least 10 seconds.

6. Repeat the following procedure quick
ly five times within 5 seconds.
- Fully depress the accelerator pedal.
- Fully release the accelerator pedal.

9. Start engine and let it idle.
10. Wait 20 seconds.
>> 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 specifi-
cations.
For specification, refer to EC-478, "
Idle Speed" and EC-478, "Ignition Timing".
Is the inspection result normal?
YES >> INSPECTION END
NO >> GO TO 5.
5.DETECT MALFUNCTIONING PART
Check the following
• Check that throttle valve is fully closed.
• Check PCV valve operation.
• Check that downstream of throttle valve is free from air leakage.
Is the inspection result normal?
YES >> GO TO 6.
NO >> Repair or replace malfunctioning part.
6.DETECT MALFUNCTIONING PART
Engine component parts and their installation conditi on are questionable. Check and eliminate the cause of
the incident.
It is useful to perform “TROUBLE DIAG NOSIS - SPECIFICATION VALUE”. Refer to EC-151, "
Description".
If any of the following conditions occur after the engi ne has started, eliminate the cause of the incident and
perform Idle Air Volume Learning all over again:
• Engine stalls.
• Erroneous idle.
