The licensing fees to get the information is insane, or the company making the tools has to spend lots of time reverse engineering all the protocols.
So yea, the tools costs 5-10 times what their worth because of that.
I could be wrong, but the Elmscan and OBD Link, look like they are little more than toys to play around with, NOT really tools, you can NOT retrieve codes, you can't clear them, you can't retrieve/clear codes in all the modules all over the vehicle, you can't initiate maintenance operations or self-tests, enter/change configuration data. The tools that can do that costs $500 and then only for one manufacturer, i.e. you have to pay through the nose for each manufacturer you want those features.
Even then those expensive tools can NOT do the, activation of new modules, flash non-volatile data like VIN#, mileage, etc and flash new software to the module. Those tools costs thousands of dollars, like the Dealer Tool that can costs $17k. And the dealer tool is just software on a cheap laptop with a cable. Even worse, more than a few of the procedures require connecting to a corporate database that you have to have a dealer account to do.
Maybe on ebay you can find a used tool for $30-$50 that is capable of reading OBDII codes and clearing them, they run $100 new, and those do NOT read the codes for all the modules, you can have warning lights on the dash on the tools will NOT read any codes from the modules that are setting the warning lights.
