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.
5. Confirm that accelerator pedal is fully releas ed, turn ignition switch ON and wait 3 seconds.

The specification (SP) value indicates the tolerance of
the value that is displayed in “SPEC” of “DATA MONI-
TOR” mode of CONSULT during normal operation of the Engine Control System. When the value in “SPEC” of
“DATA MONITOR” mode is within the SP value, the Engine Control System is confirmed OK. When the value
in “SPEC” of “DATA MONITOR” mode is NOT within the SP value, the Engine Control System may have one
or more malfunctions.
The SP value is used to detect malfunctions that may af fect the Engine Control System, but will not light the
MIL.
The SP value will be displayed for the following three items:
• B/FUEL SCHDL (The fuel injection pulse width programmed into ECM prior to any learned on board correc- tion)
• A/F ALPHA-B1 (The mean value of air-fuel ratio feedback correction factor per cycle)
• MAS A/F SE-B1 (The signal voltage of the mass air flow sensor)

peed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CA N communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
