Good afternoon, best regards, I will explain to you, I am looking for the electronic diagram of a Sagen Safir 55-pin ECU. This ECU has inside a processor with the nomenclature TMS374C00APQQ. This processor is responsible for activating the fuel pump, temperature indicator, among other things. This processor is responsible for activating the fuel pump. There were two tracks from the corner, I suppose due to the heating of said ECU, now in the vehicle two cylinders are not working, cylinder 3 and 2, I already checked the mechanical part and the failure comes from the ECU. I hope for the help you can give me and collaborate with me. :
