Mercedes ME9.7 AMG SCN Coding Problems

[nemiro]

I am having an issue with coding and flashing ME9.7 AMG modules. I have tried many combinations of hardware and software. First I will describe the problem, and then the steps I have taken to attempt to fix it. I try to perform a coding (or flashing) operation, with Vediamo 4.02.02 (AutoGMT version) or Vediamo 5 (AutoGMT), and I get this error:


Error: Service execution failed. Reason: CEASAR: DiagManager: 06067: DiagService refused.

This would indicate that the ECU is not unlocked. I have tried the various DJ_Zugriffsberechtigung selections, getting the Result: 0 response that we are looking for. I have tried this with four different ECU modules. Two regular ME97AMG (2MB) and two 66MHz ME97AMG (4MB) modules. I have a tried direct connection to the ECU on the bench, and in vehicles (via the ZGW, etc). Always the same results.

Moving over to DAS (both through Xentry and DAS Standalone) results in "Communication Error" dialog boxes, which also indicate a locked ECU. Monaco gives NRC=22, NRC=44 or NRC=88, depending on which unlock commands had been issued ahead of time.

I have also tried this on three different laptops, with software running natively and in VMs. No differences. Always the same error.

As for connection hardware, I have now tried C4, Openport Tactrix and SM2Pro. Again, all give the same 'Refused' error.

Lastly, a very knowledgeable person logged in to my machine, and tried it, and he also had the same result.

This leads me to believe that there is:
1. Likely not a hardware or PC issue, as so many combinations give the same exact result
2. Not necessarily a software issue as Monaco, Xentry, DAS and Vediamo all fail
3. Not likely an ECU hardware or firmware issue, as I have four different ones (that all run the engines to the cars they go to)
4. Some procedure I am missing or doing wrong

All other functions seem to work just fine. I can interect with the modules. Virginize them via VVDI, and then teach in drive authorization. Read actual values, do adaptation resets, camshaft teach in, etc. Just cannot flash or code these.

I have read many times that ME97 is a "seedless" ECU. Seed Key options are in the menus, but I have been unable to get any of that to work. Surely someone else out there has encountered this, and knows what to do? Please help!

ME 9.7 is easily encoded in DAS.
1. Engine off, ignition ON
2. Activations DJ_Zugriffsberechtigung... result 0 (inverse)
3. Implicit_Coding_ME97
There are errors, but you re-enter the block and that’s it.
True, I use C4. OPport 2.0 does not always work correctly.

1. This is an ME9.7 AMG version, which may explain some of the problem
2. I have tried C4, as well as Openport 2.0 and SM2Pro
3. A friend did a test yesterday on a C63 (66MHz) and was successful with a C4. However, he is using the Samik version of Vediamo, not the AutoGMT. I will set up a new machine with the Samik Fullfix version today and see if that makes any difference at all. Perhaps there is a. dll difference somewhere...

Figured out the problem! If you are building a bench programming rig, most guides will tell you that you need one of the grounds, +12V going to pins 15 and 16, and CAN-C bus. In addition to this, you need to activate Terminal 87 power at pins 3 and 5. Suddenly, everything will work! What makes this odd is that I had problems in the car coding, as well. It appears I have additional troubleshooting to do there, too.

I retested with VM's running both Vediamo 4 and 5, with Star C4 and SM2Pro, and this checks out. I also tested with an early (2007) ME.97AMG ECU and a later 66MHz version I was able to code both ECU's with both sets of software and J2534 hardware.

Most likely the problem is that the multiplexer did not see terminal 87 (IGN ON).

 

[nemiro]

Technically, the ECU did not see Terminal 87. The multiplexer does not connect to Terminal 87 directly.

Firstly I don't think this operation can be done with any Passthru like Openport as there is no real hardware for Vediamo, secondly Vediamo 4.0 is not designed for C4 MUX but for RS232 interfaces like the old C3. On the right side of Vediamo are the original files, and on top is the extended menu, in this menu open the ECU, unlock the transport mode, you have 5 minutes to configure everything you need except V-MAX, then do a hardware reset. For this operation, of course, you shouldn't use those crazy CBF files, use VSB/VSC. DTS Monaco is a basic software, a competing product that uses the same CBF as Xentry, do not work with these files.

It is all working, now. As for C4 vs Openport vs SM2Pro, all three will work for this, and I have tested each. C4 will work on Vediamo 4 or 5. Openport and SM2Pro will only work (properly) under Vediamo 4.

 

[Bigovic]

Yes, we see how it works. It works incorrectly there, it works with an error there, Vediamo only uses SDC4 or Genuine eCOM, everything else is crap, forget about it! I have been working with Vediamo since 2014, long before many people knew or heard what Vediamo was!
