on the vin function if autel engineers could add/edit in pcm and skim/win/wcm the vin change option will be great, not the way it was so they can't keep messing it up, but rather like this, one can be able to write the vin without having to read it, in other words 2 options, one will read the vin,and the other one, separate can write the vin straight up no questions asked. for the pcm vin and also for the skim/wcm/win and the ipc or mechanical cluster,tipm or fcm is also a must. thank you. one function can not do without the other. if one tries to program skim/wcm and the tipm,pcm,ipc, skim,wcm/win has a different vin then the option its not going to work, even with the correct pin code, all vin # must match. you will get a lot of complaint and data logs for invalid pin codes error as well if this is not resolved.
snap-on and drew-tech can change this vin numbers and reset skim without a single issue at all. you got to do better than this, every single tool on the market as of now is doing much better than this one do to all your issues, please lets fix them now.
