Some companies don't even feel good enough to just use maker specific codes. A couple of american car makers (who's non-ISO standards were rolled into the SAE standard) use a proprietary signalling method... and a german car maker has a 9600bps mode that normal scanners can't get to.
I am less offended at the special codes than I am at the wonk comm meathods used to get the codes from the car. Don't computers already HAVE a pretty reliable method to talk to one another?
