900 S Convertible L4-2290cc 2.3L DOHC EFI (1997)
IGNITION KEY IN START POSITION
NOTE: Ignition switch terminals +15 ON and +54 OFF.
With the ignition key in start position the fan should, if it has been switched on, go from high speed to low speed and then, after 2 seconds, switch
off completely.
If the fan's high-speed position is to be connected after the ignition key has been in start position, the low-speed position should be connected for 2
seconds and the fan should then switch to high-speed. A 2-speed fan can only be run at low speed when the ignition is switched off (+15 off and
+54 off).
If the sensor shows readings outside the limit values -60 to -30°C (-76 to -22°F) or +130 to +160°C (+266 to +320°F) the ICE waits for 0.5
seconds, after which the cooling fan's low speed is switched on.
IGNITION SWITCHED OFF
NOTE: Ignition switch terminals +15 and +54 OFF.
When the ignition is switched off (+15 off and +54 off), the ICE measures the coolant temperature for 20 minutes. During this time the cooling fan
could be activated, but only at low speed and for a maximum of 3 minutes.
With the ignition key in drive position (+15 on and +54 on3 the ICE measures the coolant temperature and the pressure in the A/C system to check
the cooling fan.
The ICE receives information about the coolant temperature from the temperature sensor in the cylinder block.
This information is also sent to the temperature gauge in the main instrument.
