Before performing idle air volume learning, 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 greater than 12.9 volts at idle.
• Engine coolant temperature 70-99°C (158-210°F).
• PNP switch ON.
• Electric load switch OFF. Air conditioner, headlamp, rear window defogger OFF. On models with daytime light systems, set lighting switch to the 1st position to light only small lamps.
• Steering wheel at Neutral. Straight-ahead position.
