Idle Air Volume Learning: Preparation

Before proceeding, ensure the following conditions are met:

• Battery voltage: more than 12.9 volts at idle.
• Engine coolant temperature: 158-212°F (70-100°C).
• Transmission: Park or Neutral.
• A/C, headlights, rear window defogger: Off.
• Headlight switch: 1st position (only on vehicles with daytime running lights).
• Steering wheel: straight-ahead position.
• Vehicle speed: zero MPH.
• Transmission: warmed up. If using CONSULT-II on A/T-equipped vehicle, confirm FLUID TEMP SE in DATA MONITOR mode of A/T system indicates less than 0.9 volt. If not using CONSULT-II, drive vehicle for 10 minutes to warm up transmission.
