KI221 Communication

[FlashY7]

hi guys,

having issue with Unlock KI221. Its connecting well but when i want unlock a level, its not doing it. 10 03 ok, 10 92 ok, 27 01,FD not ok.
When continue trying more things, it stops even to receive the commands until you do a reconnect.

I used the last build I found in the KI211 thread. CaesarSuite_dbg_2023_02_02-A
Last official Build its also not working with it, but there you can see only in TRACE after 1 minute around: the 27 01 requested seed key.

I have tested same Build on same PC for IC172, its working perfect.

Anyone idea?

Best regards

If you try to unlock KI221 on bench, you won't be able to do it. This issue was also found by Feezex: jglim/UnlockECU#21

Thank you for answers.

Iam trying in the car, not bench.

When taking vedi or other tools, I can send commands and get direct the requested keys.

Hello FlashY7,

Since the same J2534 device works in Vediamo but not here, this is likely to be a valid issue.

In 7F 27 80, the NRC is "ISO SAE Reserved" which doesn't explain much about the issue. From what I can tell from the trace, the connection appears to be up, but the ECU is actively rejecting the 27 request only.

Could you consider uploading both (Vediamo/Diogenes) j2534 traces using J2534-Shim? This post will explain the setup process. This setup takes some effort, but will produce detailed logs to compare the difference with Vediamo.

Hi jglim,

i have just did it. I logged 1x ved and 2x with different builds of CaesaerSuite.
So what I see is, ved is taking and reacting on every UDS I send without any issue.

CaesarSuite seems you can send some UDS, than again come no answer - its looking like the SW is stucking to receive or send commands. Even 11 01, 10 03 in such moment not work. But, when you "wake" it with 10 92, you can do 27 01, 11 01, 10 03 and all.
But after it, again not working. 27 02 seems to be not working in any moments - no Mather if you wake it before send key, its gives anyway 7F 27 80.

@FlashY7 I'm still looking at this issue, and it is interesting to see that there are 67 01 responses in the 2022 trace.

In the meantime, if you are keen to try a "development" build, this version of Diogenes has a rewritten networking stack that behaves a bit more like Vediamo. Most features are not implemented yet as I am still getting the connectivity in order. I have only tested this on UDS targets as I do not have any KW2C3PE devices to try on.

The new build requires .net 5 or later. The interface has some changes; here is a screen recording on how to connect to an ECU:

Hi jglim,
this diogenes 2 looks very nice. simple and clean! I took the KI221 and I took IC172 for testing. Both cannot connect or recognize the variant. I attache you both Loggs from Shim and some Screenshots. Let me know if I can test more iam ready for it!

Diogenes 2 test ki211, can't connect and recognize the variant.

Hi folks, I appreciate the positive feedback and the bug reports very much. I've attached to a CRD3 on the bench, encountered the same issue (still UDS) and applied a fix:

i have just try it. I was able to connect, unlock it, and I was able to read and write the whole EEPROM of KI221.
The rollover popup about the "READ FROM ECU" button is super helpfull! Great Idea!
Needed some clicks to find how to drag down the Interactive console / Interpreter Log - to find the other buttons of Memory Editor. However, great job!!
Lets continue for the DTC, Coding and Services inside Diogenes II ! :)
