Operation With Ignition On

Ashen the ignition switch is in the ON position, DICE uses the following information:

Without A/C
^ Coolant temperature (bus from MIU)


With A/C
^ Coolant temperature (bus from MIU)
^ A/C pressure (own pressure gauge)
^ Car speed (bus MIU)
^ Outside temperature (bus from SID)
^ A/C system status (active/inactive)

For further information on the A/C system and how it is controlled, refer to Heating and Air Conditioning.

When the A/C clutch operates, the radiator fan is activated as follows:
^ Coolant temperature
Low speed is activated when coolant temperature reaches 100°C.
Low speed is turned off when the temperature drops to 96°C.
High speed is activated when coolant temperature reaches 113°C.
High speed is turned off when the temperature drops to 109°C.


Outside temperature
Low speed is activated when the outside temperature exceeds 22�C and turned off when the temperature drops below 20�C.


Car speed / A/C pressure
Low speed is activated when car speed is below 38 km/h at the same time as A/C pressure is between 9 and 18 bar. Low speed is turned off when car speed exceeds 40 km/h or A/C pressure drops below 7 bar.


A/C pressure
High speed is activated when A/C pressure exceeds 18 bar and turned off when A/C pressure drops below 14 bar.
