NOTE:
- The fault is detected if the coolant temperature at engine start was > 35 °C (95 °F)... > 75 °C (167 °F) (depending on time since engine was switched off). (e.g. off period 6 h A Coolant temperature when engine starts > 75 °C (167 °F)

Diagnostic conditions
- Time since engine off > 6 h
- Intake air temperature when engine starts < 55 °C (131 °F)
- When the engine starts, the ambient temperature may differ from the intake air temperature by a maximum of 10 °C (18 °F)
- Engine running > 30 s
