IDLE AIR VOLUME LEARNING
DescriptionINFOID:0000000009462557
Idle Air Volume Learning is a function of ECM to learn
the idle air volume that keeps engine idle speed within
the specific range. It must be performed under the following conditions:
• Each time the electric throttle c ontrol actuator or ECM is replaced.
• Idle speed or ignition timing is out of the specification.
Work ProcedureINFOID:0000000009462558
1.PRECONDITIONING
Check that all of the following conditions are satisfied.
Learning will be cancelled if any of the following 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 position: P or N
• Electric load switch: OFF
(Air conditioner, head lamp, rear window defogger)
On vehicles equipped with daytime light systems, if the parking brake is applied before the engine is
started the head lamp will not illuminate.
• Steering wheel: Neutral (Straight-ahead position)
• Vehicle speed: Stopped
• Transmission: Warmed-up
- With CONSULT: Drive vehicle until “ATF TEMP SEN” in “DATA MONITOR” mode of “CVT” system indicates
less than 0.9 V.
- Without CONSULT: Drive vehicle for 10 minutes.
Will CONSULT be used?
YES >> GO TO 2.
NO >> GO TO 3.
2.PERFORM IDLE AIR VOLUME LEARNING
With CONSULT
1. Perform Accelerator Pedal Released Position Learning. Refer to EC-681, "Work Procedure"
.
2. Perform Throttle Valve Closed Position Learning. Refer to EC-682, "Work Procedure"
.
3. Start engine and warm it up to normal operating temperature.
4. Select “IDLE AIR VOL LEA RN” in “WORK SUPPORT” mode.
5. Touch “START” and wait 20 seconds.
Is
“CMPLT” displayed on CONSULT screen?
YES >> GO TO 4.
NO >> GO TO 5.
3.PERFORM IDLE AIR VOLUME LEARNING
Without CONSULT
NOTE:
• It is better to count the time 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-681, "Work Procedure"
.
2. Perform Throttle Valve Closed Position Learning. Refer to EC-682, "Work Procedure"
.
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 5 times within 5 seconds.
- Fully depress the accelerator pedal.
- Fully release the accelerator pedal.
7. Wait 7 seconds, fully depress the accelerator pedal for approx. 20 seconds until the MIL stops blinking
and turns ON.
8. Fully release the accelerator pedal within 3 seconds after the MIL turns ON.

The specification (SP) value indicates the tolerance of
the value that is displayed in “SPEC” in “DATA MONI-
TOR” mode of CONSULT during normal operation of the Engine Control System. When the value in “SPEC” in
“DATA MONITOR” mode is within the SP value, the E ngine Control System is confirmed OK. When the value
in “SPEC” in “DATA MONITOR” mode is NOT within t he SP value, the Engine Control System may have one
or more malfunctions.
The SP value is used to detect malfunctions that may affect the Engine Control System, but will not illuminate
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/B2 (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)
Component Function CheckINFOID:0000000009462571
1.START
Check that all of the following conditions are satisfied.
• Vehicle driven distance: More than 5,000 km (3,107 miles)
• Barometric pressure: 98.3 - 104.3 kPa (1.003 - 1.064 kg/cm
2, 14.25 - 15.12 psi)
• Atmospheric temperature: 20 - 30 °C (68 - 86 °F)
• Engine coolant temperature: 75 - 95 °C (167 - 203 °F)
• Transmission: Warmed-up
- After the engine is warmed up to normal operating tem perature, drive vehicle until “FLUID TEMP SE” (CVT
fluid temperature sensor signal) indicates more than 60 °C (140 °F).
• Electrical load: Not applied
- Rear window defogger switch, air conditioner switch li ghting switch are OFF. Steering wheel is straight
ahead.
• Engine speed: Idle

2.PERFORM “SPEC” OF “DATA MONITOR” MODE
With CONSULT
NOTE:
Perform “SPEC” in “DATA MONITOR” mode in maximum scale display.
1. Perform basic inspection. Refer to EC-675, "Work Procedure"
.
2. Select “B/FUEL SCHDL”, “A/F ALPHA-B1”, “A/F ALPHA-B2” and “MAS A/F SE-B1” in “SPEC” of “DATA
MONITOR” mode with CONSULT.
3. Check that monitor items are within the SP value.
Is the measurement value within the SP value?
YES >> INSPECTION END
NO >> Proceed to EC-702, "Diagnosis Procedure"

before conducting the next test.
1. Turn ignition switch OFF and wait at least 10 seconds.
2. Turn ignition switch ON.
3. Turn ignition switch OFF and wait at least 10 seconds.
>> GO TO 2.
2.PRECONDITIONING-II
With CONSULT
1. Turn ignition switch ON.
2. Check the following conditions:
3. Select “DATA MONITOR” mode of “ENGINE” using CONSULT.
4. Check the following conditions:
Is the condition satisfied?
YES >> GO TO 3.
NO >> 1. Satisfy the condition.
2. GO TO 3.
3.PERFORM DTC CONFIRMATION PROCEDURE-I
With CONSULT
1. Start engine.
2. Drive the vehicle until the following condition is satisfied.
CAUTION:
Always drive vehicle at safe speed.

To judge malfunctions, the diagnosis c
hecks that the A/F signal computed by ECM from the A/F sensor 1 sig-
nal fluctuates according to fuel feedback control.
DTC CONFIRMATION PROCEDURE
1.PRECONDITIONING
If DTC Confirmation Procedure has been previously conduc ted, always perform the following before conduct-
ing the next test.
1. Turn ignition switch OFF and wait at least 10 seconds.
2. Turn ignition switch ON.
3. Turn ignition switch OFF and wait at least 10 seconds.
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is more than 11 V at idle.
>> GO TO 2.
2.PERFORM DTC CONFIRMATION PROCEDURE FOR MALFUNCTION A
1. Start engine and warm it up to normal operating temperature.
2. Let engine idle for 2 minutes.
3. Check 1st trip DTC.
Is 1st trip DTC detected?
YES >> Proceed to EC-755, "Diagnosis Procedure".
NO-1 >> With CONSULT: GO TO 3.
NO-2 >> With GST: GO TO 7.
3.CHECK AIR FUEL RATIO (A/F) SENSOR 1 FUNCTION
1. Start engine and warm it up to normal operating temperature.
2. Select “A/F SEN1 (B1)” or “A/F SEN1 (B 2)” in “DATA MONITOR” mode with CONSULT.
3. Check “A/F SEN1 (B1)” or “A/F SEN1 (B2)” indication.
Does the indication fluctuate around 2.2 V?
YES >> GO TO 4.
NO >> Proceed to EC-755, "Diagnosis Procedure"
.
4.PERFORM DTC CONFIRMATION PR OCEDURE FOR MALFUNCTION B-I
1. Select “A/F SEN1 (B1) P1276” (for DTC P0130) or “A/F SEN1 (B2) P1286” (for DTC P0150) of “A/F
SEN1” in “DTC WORK SUPPORT” mode with CONSULT.
2. Touch “START”.
3. When the following conditions are met, “TESTING” will be displayed on the CONSULT screen.
DTC No. Trouble diagnosis name DTC detecting condition Possible cause
P0130 Air fuel ratio (A/F) sensor 1
