| Enable Conditions |
Case1 |
- Less than 10% of percentage of deceleration fuel cut-off time
- Less than 60% of percentage of low load state (vehicle speed less than 20km/h (12.43MPH))
- Less than 15% of percentage of high speed state (vehicle speed more than 90km/h (55.92MPH))
- Less than 50% of percentage of low speed (engine load less than 8.0 to 15.0%)
- Coolant temperature should not drop much at high engine speed
- High engine speed standard (more than 4500RPM)
- High engine speed for more than 40s
- Engine coolant temperature decrease is more than 2°C (35.6°F) at high engine speed
- Engine coolant temperature at startup is more than -10°C (14°F)
- Intake temperature is more than -6°C (21.2°F) at the start
- Ambient temperature is more than -8°C (17.6°F)
- No relevant failure

| Case2 |
- Engine coolant temperature at startup is more than -10°C (14°F)
- Ambient temperature is more than -10°C (14°F)
- Engine coolant temperature after engine "ON" is higher than 77°C (170.6°F)
- Intake air volume is higher than 4.2 to 152.8g/s
- Vehicle speed is higher than 40 to 80km/h (24.8 to 49.7mph)
|
| Threshold Value |
Case1 |
- When the measured coolant temperature is below 77°C (170.6°F) while the coolant model temperature is above 84°C (183.2°F)
|
| Case2 |
- When the measured cooling water temperature is 56°C (132.8°F) or less while the measured intake air volume is higher than 556 to 1667g/s
