Anyone who knows where the ECU is situated and how to test it? Acc. to the work shop manual you need tha "ferrari tester" to check if it is working ok. It might be the ECU that failes to tell the fan how to operate. //B//
The Motronic ecu's are located behind the seats. Unfortunately for you the euro model 348s don't have the self test button. A few months back we were talking about if you could hook up a button to the ecu to pull the codes on a Euro model, but never really came to any conclusion. Now if you are talking about the climate control ecu it's located in the middle instrument housing, behind the climate control panel.
