900 SE Hatchback L4-1985cc 2.0L DOHC Turbo EFI (1997)
ICE sends the temperature signal to the main instrument display panel. The main instrument display panel uses this to control the temperature
gauge and send the coolant temperature signal to the ACC control module. The ACC control module uses the coolant temperature as an input
value to decide whether the cold starting mode of operation is applicable. If it is, air distribution and fan speed are adjusted as a function of the
coolant temperature.
If no coolant temperature signal can be obtained, the ACC control module calculates a default value which on starting is 0 °C and gradually rises
to 100 °C.
