Hello, after battery drain my car can’t see the eps module. I’ve tried code vcm but without success. There is always end with negative response error and Ista can’t see module. Wiring is ok, but I think there is flexray signal problem from zgw.
Reset flexray and try to read the module
maybe you need start flexray with ista or tool32 if you cant whit ista.
This was first that I tried but with no success. After the I saw with oscilloscope that signal is not typical flexray signal, and after that change zgw with other and everithing was ok since then. Thanks for help !
