Cruzkid,
Well Sir, it all depends on what you mean by "computer". As has been stated, you most likely have at least one "ECM" , otherwise known as an Engine Control Module. Each year, they come out with new and improved versions of computers and modules for running various parts of the coach. The engine is controlled by its ECM, the later transmissions, like our Allison MH3000 6-spd has its own "TCM", or, Transmission Control Module".
Then, your unit could also possibly have what's known as an "ABS" module. Or, Anti-Lock Braking System module. Then, there's what's called a "VCM" or, Vehicle Control Module", the later version, what we have in our '04 Itasca Horizon 36GD with the C-7 330 CAT, is called an "MMDC" or, Multi-Module-Data-Controller" Both of those later items are units that receive data from all the other "CMs" and either change it or, decipher it and transmit it to the various gauges and dials.
So, do you have any of the above? Most likely. Just what version, not a clue. Engines, both gas and diesel have had electronic controls for quite some time now. The later the engine(s), the more technical the versions of the controllers are. The newest ones, you just about have to be a graduate of MIT to be able to analyze and work with them. Good luck.
