Heavy trucks and farm equipment OEMs are dicks. For most cars an Autel can do a lot of heavy lifting until you get into module reprogramming. Something like Oil pressure isn’t on the OBDII standard for some dumb reason.

I wish that they made it a law that any canbus data has to have the key released into the publoc domain so any scantool can give that data. They can keep their specific module reprogramming hardware and software access subscriptions, but the data in the network should be available.
