Hi guys,
someone, has the complete scheme of this ECU? or diagram for a repair? ( IAW 1AP.41 )
I have a original DIAG 2000, an old ECU, on a test bench, but the result is: "THE CALCULATOR DID NOT RESPOND"

I would like to understand, if I connected it right for the diagnosis,
if instead the control unit was damaged, it would serve a scheme to test the power supplies on the tracks.

I connected

obd pin          IAW 1AP.41 pin                 PSU 12v
1                      13 & 35                             +12
4                      36 & 54                              NEGATIVE
7                      31 ( K line )
12                    12 ( L line )
16                                                             +12


is it necessary to connect the transponder for diagnosis?

or does it only serve to start the engine? pin 27 & 48 ??


thanks in advance for this adventure

Hi, you can make diagnose after immo off or on car and immo not active.

I almost imagined, can I do immo off without reprogramming? I do not have eprom sockets and programmers available, I want to try tweezer method? where can I find the guide?

[pankar]

The best method is immo off from tms. With the tweezer method, first make backup the 28f512.

I did not backup, because I do not have a plinth and a programmer ... I did tweezer, but now the diagnosis light remains fixed, even turning off the pin1 obd contact. having said this, I just wanted to do a test on this unit, to try the download with Diag 2000 of actia. (I think I have everything I need) is a test to see if the Diag works, before damaging the ECU on the car. the problem is that I do not know if the control unit on the desk is faulty. Thanks again. every help and suggestion is welcome. when the test is finished, I can put all the photos and procedures, accessories, and tools used.
