Description

NoteThermistor with connector (1) 2 way brown

The thermistor relays the engine temperature to the 8010 unit by measuring the coolant temperature

Its electrical resistance is of the PTC type (Positive Temperature Coefficient); this resistance increases as the temperature increases

The thermostat measures the engine temperature via the thermistor

The ECU carries out the following functions

Controls the fans via relays
Illuminates the warning lights on the instrument panel (stop + maximum water temperature)
Cuts out the air conditioning function via relay 8015 (a)
Transmits Engine Hot information to the vehicle air conditioning unit (a)
Controls the post-cooling (a)
Controls the fans at high speed in the case of refrigerant pressure greater than 17 bars (a)

Note(a) according to equipment

-	3	on certain carburettor versions, input of earth information from the exterior heat switch	C.O.
1B	4	permanent +ve 12 V supply for ECUs which control post-cooling	permanent +ve 12 V
3A	5	vehicles with air conditioning: input of +ve 12 V information when the user presses the A/C button this information triggers the low speed fan control	C.O.
1A	6	controls the warning lights on the instrument panel by earthing this outlet	12 V

-	9	for vehicles fitted with temperature regulation: transmits Engine Hot (48 °) information to the air conditioning ECU by earthing this outlet	C.O.
2A	10	controls the high speed fan by earthing this outlet	12 V
2B	11	vehicles with air conditioning: cuts out the air conditioning compressor by earthing this outlet	12 V
-	12	not used	-
6B	13	vehicles with air conditioning: input of +ve 12 V information from the pressure switch this information indicates that the coolant pressure has reached 17 bar(s) this information triggers the high speed fan control	C.O.
4A - 5A	7 - 14	the ECU delivers a constant 1 mA current and measures the resistance of the thermistor which is connected between these terminals a break or short circuit between these terminals sets the fans to high speed and prevents the air conditioning operation	0≤R≤<5000 Ω
5B	15	ignition controlled 12 V supply to the ECU	+AC (+KK)
