Conditions for Running

Non-scan tool service bay test equipped vehicles:

• Barometric pressure is more than 75 kPa.
• Fuel level is between 1/4 and 3/4 full.
• Battery voltage is 10-18 volts.
• Test will only initiate after a cold start. PCM considers engine cold if Engine Coolant Temperature (ECT) is 39-86°F (3.75-30°C), Intake Air Temperature (IAT) is 39-86°F (3.75-30°C) and difference between ECT and IAT is less than 14°F (8°C).

Scan tool service bay test equipped vehicles:

• Barometric pressure is more than 75 kPa.
• Engine Coolant Temperature (ECT) is less than 176°F (80°C).
• Fuel level is between 1/4 and 3/4.
• Battery voltage is 10-18 volts.
