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:0000000001161441
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 12.9V (At idle)
Engine coolant temperature: 70 - 100°C (158 - 212°F)
Park/neutral position switch: ON
Electric load switch: OFF
(Air conditioner, headlamp, rear window defogger)
On vehicles equipped with daytime 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
- For A/T models
With CONSULT-III: Drive vehicle until “FLUID TEMP SE” in “DATA MONITOR” mode of “A/T” system indi-
cates less than 0.9V.
Without CONSULT-III: Drive vehicle for 10 minutes.
- For M/T models
Drive vehicle for 10 minutes.
