Idle Air Volume Learning: Pre-Conditioning

Before proceeding, ensure the following conditions are met:

• Battery voltage: more than 12.9 volts at idle
• Engine coolant temperature: 158-210°F (70-99°C)
• Transmission: Park or Neutral
• A/C, headlights, rear window defogger: Off
• On vehicles with daytime running lights, if the parking brake is applied before the engine is started, the headlights will not illuminate.
• 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 .9 volt. Or, drive vehicle for 10 minutes to warm up transmission.
