Conditions For Running

Non Scan Tool Service Bay Test

• The barometric pressure is more than 22 in. Hg (75 kPa).
• Fuel level is 1/4 and 3/4.
• The battery voltage is 10-18 volts.
• The test will initiate only after a cold start. The control module considers the engine to be cold if the following conditions are met:
  1. Engine Coolant Temperature (ECT) is 39-86°F (3.8-30.0°C).
  2. Intake Air Temperature (IAT) is 39-86°F (3.8-30.0°C).
  3. The difference between the ECT and IAT is less than 14°F (8°C).
