I have to agree with you Eddie2, and I kind of think that was part of the reasoning when MCF* put a page in the truck's operator's manual (that goes with -each- truck) that lists out the codes and a short explanation for the codes.
Although I am not all that sure that it is a bad thing that we have to get "trained up" on the brands we work for, after all, we are supposed to be the "experts" on those brands, and that is at least part of the reason we can demand a little more money for our services. I am not sure I want to be the lowest -price- option for service, more that I want to be the most cost effective option.
and besides, it it was _easy_, someone else would get to do it.
