Low speed

WARNING: This page is about a different car, the 2001 Saab 9-3. However, it is still accessible from the selected car via links, so may be relevant.

DICE uses the values which fulfil the conditions for low-speed running to start the radiator fan at low speed. The relay (155) is then grounded via pin 35 of the control unit. Current is supplied to the radiator fan which starts and runs at low speed because the current is reduced by a series resistor (367).
