INSPECTION AND ADJUSTMENT
• Each time electric throttle control actuator or ECM is replaced.
• Idle speed or ignition timing is out of specification.
IDLE AIR VOLUME LEARNING
: Special Repair RequirementINFOID:0000000005929760
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 (A/T), Neutral (M/T)
• Electric load switch: OFF (Air conditioner, headlamp, rear window defogger)
On vehicles equipped with daytime light systems, if the parking brake is applied before the engine is
started the headlamp will not be illuminated.
• Steering wheel: Neutral (Straight-ahead position)
• Vehicle speed: Stopped
• Transmission: Warmed-up
- A/T models
• With CONSULT-III: Drive vehicle until “FLUID TEMP SE” in “DATA MONITOR” mode of “TRANSMISSION”
system indicates less than 0.9 V.
• Without CONSULT-III: Drive vehicle for 10 minutes.
- M/T models
• Drive vehicle for 10 minutes.
Do you have CONSULT-III?
YES >> GO TO 2.
NO >> GO TO 3.
2.IDLE AIR VOLUME LEARNING
With CONSULT-III
1. Perform Accelerator Pedal Released Position Learning. Refer to EC-25, "
ACCELERATOR PEDAL
RELEASED POSITION LEARNING : Special Repair Requirement".
2. Perform Throttle Valve Closed Position Learning. Refer to EC-25, "
THROTTLE VALVE CLOSED POSI-
TION LEARNING : Special Repair Requirement".
3. Start engine and warm it up to normal operating temperature.
4. Select “IDLE AIR VOL LEARN” in “WORK SUPPORT” mode.
5. Touch “START” and wait 20 seconds.
Is
“CMPLT” displayed on CONSULT-III screen?
YES >> GO TO 4.
NO >> GO TO 5.
3.IDLE AIR VOLUME LEARNING
Without CONSULT-III
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 Released Position Learning. Refer to EC-25, "
ACCELERATOR PEDAL
RELEASED POSITION LEARNING : Special Repair Requirement".
2. Perform Throttle Valve Closed Position Learning. Refer to EC-25, "
THROTTLE VALVE CLOSED POSI-
TION LEARNING : Special Repair Requirement".
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.
6. Repeat the following procedure quickly five times within 5 seconds.
- Fully depress the accelerator pedal.
- Fully release the accelerator pedal.
7. Wait 7 seconds, fully depress the accelerator pedal and keep it for approx. 20 seconds until the MIL stops
blinking and turned ON.
8. Fully release the accelerator pedal within 3 seconds after the MIL turned ON.

INPUT/OUTPUT SIGNAL CHART
*1: This signal is sent to the ECM via the CAN communication line.
*2: ECM determines the start signal status by the signals of engine speed and battery voltage.
SYSTEM DESCRIPTION
This system improves engine operation when the air conditioner is used.
Under the following conditions, the air conditioner is turned off.
• When the accelerator pedal is fully depressed.
• When cranking the engine.
• At high engine speeds.
• When the engine coolant temperature becomes excessively high.
