- Coolant temp, at start < 10°C (50°F)
- Minimum time (approx. 360~100sec.) after start versus coolant temperature at Start
- Modeled coolant temp. > 10°C (50°F)
- No relevant failure
- 6V < Battery voltage < 16V
|
| Threshold Value |
- Coolant temperature signal below minimum coolant temperature (10°C (50°F)) for Lambda control activation when diagnosis activation condition fulfilled
