error reading start bdm edc16c39 Opel

[Errecinque]

Hello all, today I spent the morning trying to read the ecu of Opel antara 150 hp booklet engine Z20S.The label control unit bears the following inscription
96950947. G9
08110. G9. 5081100337. SERVNO: 96892367
Made in Korea
0281015569. 1039S25968

The problem is that I do not understand that although I opened the ecu very carefully, without straining anything, connected as well as other times, gallo e xxx with checking voltage on the needles right as instructed, when I give a "connect" to the sw, I-gives error "micro not supported". I tried several times to put the e xxx needle on pitches, but nothing I part of the communication.

At that, I also connected a ktag new still from test always checking before the arrival of the 12v to the pitches right, but also this tool I gives error communication at the start of the bk

It already happened to someone and how did you resolve? What can I try to do? In the meantime, tomorrow morning I bring the ecu to the car and I hope that comes back up without problems.
Thanks for the advice

Sorry, but are you sure that's an edc16?

You sure it has the flat lid on one side and the usual pitches bdm bosch

the number hw is a edc16c39, so it is strange that you do not read it, the first thing to do is just put in the car the ecu and test if everything is ok,

I hope so....honestly I have not done anything wrong, I am very meticulous in the check the connections before applying power to the ecu....tomorrow I will tell you if the part if not I will need your help.
I was thinking if it is possible that this desire, a power supply of higher than 12V because the sw I was 12 and something and strip the green, but with a multimeter with everything connected were 11.80/11.90 on the needles. Is it possible?

these do not have big problems of voltage, if you have connected everything by the book then the problem is elsewhere.

Update....the machine is regularly game. Now the only thing that comes to mind for me to be able to read it is to clean the pitches of the bdm that could have of the wax above. If not, do you have any other idea on what to check or do, premising that the cock that has already done its function very well other times, and then find a problem hw

never clean the pitches of these ecu's, only japan because they are moulded in resin.

In fact, you're right, it did not clean them because I checked with the tester pitch for pitch, following the slopes and the points where they went, and the continuity is flawless, even between the points where arriving and needles placed all over ok....but nothing that the rooster always gives error micro is not supported. I find it strange that the voltage to the needles not yet leaned on the pitches is 12,10 while when they are placed in positions I read only 11,60 volt about as if there was an uptake in the ecu. is this normal? And one other thing, while I was checking the continuity of the plots I noticed that the gnd pin (the third one down from the left side with the comb to me) is in continuity with the other 2 pins of the pitches. Is that right ?

maybe it could just be the ecu that has some problem on the pitches ****llo connection.
