- Off: Both rear window defogger switch
and lighting switch are OFF.
IGNITION SW On/Off ×ו Indicates [ON/OFF] condition from igni-
tion switch signal.
HEATER FAN SW On/Off ו Indicates [ON/OFF] condition from the
heater fan switch signal.
BRAKE SW On/Off • Indicates [ON/OFF] condition from the
stop lamp switch signal.
INJ PULSE-B1 msec • Indicates the actual fuel injection pulse
width compensated by ECM according to
the input signals. • When the engine is stopped, a
certain computed value is indi-
cated.
IGN TIMING BTDC ו Indicates the ignition timing computed by
ECM according to the input signals. • When the engine is stopped, a
certain value is indicated.
CAL/LD VALUE % • “Calculated load value” indicates the val-
ue of the current air flow divided by peak
air flow.
MASS AIRFLOW g/s • Indicates the mass air flow computed by
ECM according to the signal voltage of
the mass air flow sensor.

IDLE AIR VOLUME LEARNING
DescriptionINFOID:0000000009462138
Idle Air Volume Learning is a function of ECM to lear
n the idle air volume that keeps each engine idle speed
within the specific range. It must be per formed 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.
Work ProcedureINFOID:0000000009462139
1.PRECONDITIONING
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.
• Battery voltage: More than 12.9 V (At idle)
• Engine coolant temperature: 70 - 100 °C (158 - 212 °F)
• Selector lever : P or N
• Electric 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.
• Steering wheel: Neutral (Straight-ahead position)
• Vehicle speed: Stopped
• Transmission: Warmed-up
- With CONSULT Drive vehicle until “ATF TENP SEN” in “DATA MONITO R” mode of “CVT” system indicates less than 0.9 V.
- Without CONSULT 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 Released Position Learning. Refer to EC-177, "Work Procedure"
.
2. Perform Throttle Valve Closed Position Learning. Refer to EC-178, "Work Procedure"
.
3. Start engine and warm it up to normal operating temperature.
4. Select “IDLE AIR VOL LEARN” in “WORK SUPPORT” mode of “ENGINE”.
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 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-177, "Work Procedure"
.
2. Perform Throttle Valve Closed Position Learning. Refer to EC-178, "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 quick ly 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.
