So, i have an idea, but first a little background on my project. most cars either fall into 2 categories, those with OBD1 (On Board Diagnostics) which was from from late 80's to 95 or those with OBDII which is from 96 to present day. With OBD1, diagnosing problems was very hard, as each manufacturer had different styles for the plugs, meaning you could not use one tool for every car but with OBDII, this was possible with the government making them standardize plugs. That said, my car is a 95 Honda with a specialized plug though i did buy an adapter to fit the standard plugs, it did not work with a generic tool, but it did work with a Honda Interface Module(HIM). Which leads me to my question.
The HIM acts basically like a translator between the cars computer and a PC, with one cable plugging into the diagnostic port on the car and another cable plugging into the USB port on the computer. With open license software being available to use a laptop as a diagnostic tool, which microcontroller would i need to be able to achieve this. I already have a raspberry pi B+ so could i get away with finding linux software, or would i need to throw and arduino in somewhere?
