>>

GO TO 2.

>>
- Replace electric throttle control actuator. Refer to Removal and Installation .
- After replacing electric throttle control actuator, perform necessary work.
PRECONDITIONING
With CONSULT 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 - 105°C (158 - 221°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
- Drive vehicle until "ATF TEMP SEN" in "Data Monitor" mode of "TRANSMISSION" system indicates less than 0.9 V.

GO TO 3.
IDLE AIR VOLUME LEARNING
With CONSULT
1. Perform Accelerator Pedal Released Position Learning. Refer to Description .
2. Perform Throttle Valve Closed Position Learning. Description .
3. Start engine and warm it up to normal operating temperature.
4. On CONSULT screen, select "ENGINE">>"Work support">>"IDLE AIR VOL LEARN".
5. Touch "START" and wait 20 seconds.
Is "CMPLT" displayed on CONSULT screen?

>>
- Replace electric throttle control actuator. Refer to Removal and Installation .
- After replacing electric throttle control actuator, perform necessary work.
>>

Retry from step 2.

GO TO 4.
CHECK IDLE SPEED AND IGNITION TIMING
1. Start engine and warm it up to normal operating temperature.
2. Let it idle for 20 seconds.
3. Rev up the engine two or three times and make sure that idle speed and ignition timing are within the specifications. Refer to Idle Speed and Ignition Timing .
Is the inspection result normal?

>>

INSPECTION END

>>

GO TO 4.
DETECT MALFUNCTIONING PART-I
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?

>>

GO TO 5.

>>

Repair or replace malfunctioning part.
DETECT MALFUNCTIONING PART-II
Engine component parts and their installation condition are questionable. Check and eliminate the cause of the incident. It is useful to perform "TROUBLE DIAGNOSIS - SPECIFICATION VALUE". Refer to Diagnosis Procedure . If any of the following conditions occur after the engine has started, eliminate the cause of the incident and perform Idle Air Volume Learning again:
- Engine stalls.
- Erroneous idle.
