Function check using actual values with HHT (warm-up)
Actual value no. | Actual value | Specified value |
| Engine coolant temperature (proceed on the basis of complaint or temperature-dependent) | °C |
| Time-dependent engine speed when hot (increased idle speed): Engine coolant temperature + 20 °C for approx. 60 s | 1050 50 rpm |
| Temperature-dependent idle speed increase (read off approx. 60 s after starting) : Engine coolant temperature - 20 °C Engine coolant temperature 0 °C Engine coolant temperature + 20 °C Engine coolant temperature + 60 °C Engine coolant temperature > 80 °C |
