I feel as though maybe this thread should be closed. There is rarely (I want to say never) a reason to disable a DTC via error class. Everything is configurable on these ecus. EVERYTHING from crash signals to CAN reception. CLAxxx hacks are old/have no place in the new world order we're working on here.

With that said, I actually used this the other day to ENABLE an error path that was omitted from a particular SW version.

Hide. I should have said Hide.

That's all this does. The fault is still present. The ecu just can't report it to you. Terrible, terrible practice.

In particular, it helps me figure out WHICH error class I'm trying to track down to trace it in the FR.. so it definitely has its place..

Ok. To remove P1118, Should I disable second 02 sensor on ESKONF?

Yes this is the preferred method, although other changes might be required.

Thanks. I am allready set CDKAT, CDHSH, CDHSHE, CDLATV, CDLASH, CDLSH to zero and CWKONLS to 1.
Now I have no P1114 and P0140 but still P1118.
But I can't find ESKONF on my file. Or maybe I have some errors with addresses above

You can probably just alter CW_CAN_R to get rid of those. Page 1634 of the german FR.
EDIT: CW_CAN_C too.

Also, it's probably a wrong thread if we speak about doing it this way. Tongue

Actually, I'm happy about this, since IMO tracking down error class vs DTC should NOT make you want to disable the error class entirely, but help you track down the root cause...
