Just something I wanted to throw out here mostly because of an annoying idiot light I have that just seems to happen now about every month. I own a late model truck I had this idiot light come on that said "Check Engine", lucky me off to a good friend that has an engine shop. Well sort of he plugs in his little probe...said I had a drop in the "vapor system fuel intake" this meant fuel lines or air intake according to him...I know computers he knows how to fix engines. What it really meant after some testing cause his a gear head and now has to deal with computers is not only pissed but lucky because any car make now days is not releasing the meaning of their codes. Anyway long story short my 2 year old Ford Ranger "Check Engine Idiot Light" was found to come on when cold or hot weather shruck or expandaded my gass cap to either exceed pressure or not have enough pressure is the gas line. Mind you by the time I simply cut the wire to the check engine light cause as we figured out it could not exceed the factory set limit of .025% in the fuel line any air bubbles meant that light would require me to go to a dealership and as far as I can tell they can set when that light will come on for about 300 to 1,200 dollars per visit depending on how honest they are.

Now I do not know about you but as many here are very aware of computers any or may may drive cars and for at least 7 years all their systems are monitored and contriled by computers. My oldest son has a VW Jetta has an beep also small drop in oil pressure not enough to hurt the engine just driving fast in Calfornia traffic and breaks to quick...beep, beep. I advised him to cut the speaker because the dealership wants $7, 000 to replace his engine.

Of the goole searchs I did I found one link http://seattlepi.nwsource.com/nation...arheads15.html it is bad enough to manage a network now days now because of DMCA..car makers only supply the codes to their dealrships $$ people.

With all this talk of computers in cars whay do the people that make them link them to an idiot light that is red or amber on the dash? Hell it gets over 70 in the inside of my 2 year old Ford Ranger lately cause I disabled the "Amber Check Engine" now I get a "RED Door Open"...ah Ford I know how to close my Truch Door.

Need more reverse engineering on the area of car computers codes and how these car makers are not fessing up.
