I have a mystery problem with the fans.When the car is cold under 20 c and I turn the key to on everything is ok no fun operation.When I start the engine then the fun operates for about 10 seconds the temp become 40-50 c and then the fans stop.
After that everything work fine fans operate at low speed on 94-95 c medium on 105 c.
I have change the thermosensor and again the same problem.
Also I have try and other ecu but the same problem.
Any ideas?

PS my car use jdm engine harness,I have cross the wires from blue connector to fit europe front harness.
Double check it and it is ok.
If I ground the pin one by one on cpu the fan operates low,medium etc.
