I do see the point you are making. There is a lot of advancement being made in the computers for the cars of tomorrow.
 
But let me give you an example of what can go wrong with the "techs" of today who don't learn basics.
Today, I had a machine that had an alternator problem.
For some reason, the alternator wasn't charging and some of the lights weren't working. The computer was telling us that the alternator wasn't charging.
 
Ok, we knew that.
Upon testing, the wire that signals the alternator to start (Some call it the signal wire, exciter wire or charge wire) didn't have voltage.
 
Here is where it gets tricky. The computer actually controls the voltage to the signal wire. So, where does the tech go?
Check the computer? It says the alternator isn't charging.
Check the alternator? Why? Alternator can't charge with out a signal.
 
Now, here's a bit to throw you, if you turned the lights on, the alternator started charging.
 
So, back to basics. Visual check.
Followed the alternator signal wire back and found that it had rubbed thru and was shorting on one of the wires that ran the headlights. (To clarify, the exciter wire had rubbed thru and partially into the headlight wiring) Headlights off, the connection was broken, headlights on, it supplied power to the alternator signal wire.
 
Repaired the wire and headlights and alternator worked fine.
 
The point of all this typing is that all the computer skills in the world wouldn't have solved this one. What solved it was basic electrical knowledge.
 
For those who I bored to death, sorry about that.

Well, I'm not so sure that a sensor couldn't tell you that a particular wire is losing voltage or current under load because of a short. So a good computer would say that wire is bad and replace it. You use voltmeters now to test loads and such I assume, so the only issue I see there is figuring out how to track that load in real time without spending a fortune on the sensors.
 
Plus I'm sure you've run into situations where the wire got pierced or something and is shorted but there's no external visible evidence of a problem.
 
I'm just tossing out terms I don't fully understand, but I think you get my drift.

"The AASP is a national consumer group based in Boston that is pushing the Right to Repair Act, now in the U.S. Congress and also the [Mass.] state Legislature.
 
The bill, if passed, will require car companies to provide independent repair shops access to all the diagnostic codes and repair information that it supplies to its dealers."

I found this article in the WSJ about the expense and ease of repairs. Apparently the IIHS and some group called the Research Coucil for Automotive Repair (RCAR) have been working together to persuade automakers to involve ergonomic design into their automobiles in relation to maintenance and repairs. Interesting article.
http://online.wsj.com/public/article_print/SB120671829721371953.html
 
It should be noted that RCAR is a collection of insurance agencies. I would imagine their agenda involves getting repair costs below the magical $1000 mark, where many folks set their deductables.

I've seen a few of those headlight replacement horror stories, so any movement to fix idiotic stuff like that would be welcome.

New Jersey moving forward by steve_ HOST

New Jersey's motoring consumers were granted "car repair" relief when three out of five Assemblypersons in the Consumer Affairs Committee today voted to pass The Motor Vehicle Owners' Right to Repair Act, A-803.
 
The legislation allows motorists to choose where, how and by whom to have their vehicles repaired, even work on their vehicles themselves. Vehicles are equipped with computers that control the repair and service information on vital systems such as, but not limited to: air bags, brakes, steering mechanisms, tire pressure, oil changes, electronics, check engine lights, transmissions and fuel injection."

Soo.... I don't get it. What does this do? I am not aware of any programming or tools that are not already available ... for a price. The article doesn't state what actions, if any, will be taken as a result of this "Act." Will manufacturers be forced to provide software for free? I seriously doubt it. Dealerships don't get it for free, so why should indy shops?
 
The only example I can use to relate to this is the indy Volvo shop I used to frequent. There was nothing they couldn't do that the dealership could do ... but they needed to invest in the same equipment as the dealer. For Volvo, that meant having the VADIS software. Very expensive, from what I understand.

Some of the shop owners complain that they invest big bucks in the equipment and software, only to discover that pieces of the software diagnostics are missing. Meanwhile the dealers get the complete set of tools.
 
The article is a bit misleading too - it sounds like the Act just got through committee and hasn't been passed or signed off on by the governor.
 
I want a wireless OBDII gizmo that will let my car talk to my computer so I can then upload the parameters to the forum or Edmunds Answers or the dealer or my indy mechanic and have someone decipher the results.
 
It's easy to run a program like HijackThis and upload the results to the net, and 10 tech heads will jump in and tell you what's going on with your computer for free. I want that for my car and maybe right to repair legislation will make the automakers go that way.
