Conditions For Running Test (Cold Start)
Ensure vehicle meets the following conditions before performing procedure:
- Barometric pressure is greater than 19.2 in. Hg (65 kPa).
- Engine coolant temperature is less than 86°F (30°C).
- The Intake Air Temperature (IAT) is less than 90°F (32°C).
- The difference between IAT and ECT is 7°F (5°C) or less.
- Battery voltage is 10-18 volts.
- Fuel level is 1/4-3/4 tank.
Test will initiate only after a cold start. A cold start is considered when engine coolant temperature is less than 35°F (2°C).
