I'm still with you father on modern vechicles. Yes--the engine light comes on, and I can read a PID trouble code on many vechicles.
The fault code is not always the problem. It's just not that simple to fix a modern vechicle. I pull a generic pid of XXXX, but maybe, around 30% of the time it's just that error code.
Manufacturers have scan tools that read there products very well. Much better than my Snap-on 2500mt. I can't buy their tools, nor will they sell their priority information to
most mechanics.
So, working on vechicles made after, I say, 2000 is really getting hard.
So hard, I believe most vechicles made in the 90's will become collectable? Why--they have less do-dads, and Emmission sensors.
It gets monumentally difficult if your trying to get a vechicle to pass CA Emmission tests.
I thought OBD2 would make working on vechicles a breeze. I have not found it to be the case.
I have found buying a new vechicle is a lifelong relationship with the dealership; at dealership repair prices. I think manufactures did this on purpose. "Get them to buy your vechicle, and keep them coming back?" A sales tatic that software companies have been relying on for years now? I still remember buying Lightroom 1 at $199.00, and thinking that's all I will spend. What a deal?
I actually foresee a bunch of bricked, by failing emmission tests, vechicles in the near future.
