There are companies around that offer VIN re-coding by mail order if you need to swap one of the computers, but you'd have to be in a fairly big metro area to profitably run a company just doing electronic trouble shooting. It's easier just to "fire the parts cannon" after the usual suspects (dead sensors, shorted wiring) have been accounted for.
Having had a 2006 model car in my workshop forever rebuilding the engine, I have though it might be worthwhile starting a business doing that kind of trouble shooting but nobody will want to pay, because the vehicles involved are inevitably old and worthless. It's fun to do it for yourself, but as a business your typical customer who needs you won't be able to justify paying you.
My other thought was to possibly set up the tools and whatnot to support local businesses in doing that kind of troubleshooting on older cars but building the knowledge and tools to distribute would be a very expensive exercise.
I love this phrase, and it reminds me that the behavior exists in the computer world too. From the Jargon File:
field circus: [a derogatory pun on `field service'] n. The field service organization of any hardware manufacturer, but especially DEC. There is an entire genre of jokes about DEC field circus engineers:
Q: How can you recognize a DEC field circus engineer with a flat tire?
A: He's changing one tire at a time to see which one is flat.
Q: How can you recognize a DEC field circus engineer who is out of gas?
A: He's changing one tire at a time to see which one is flat.
