Which is stupid. I bought a $300 code reader (it's a really nice one) a few years back to help with diagnosis... It turns out, $80 per code is just dumb. Sometimes there's 3 codes on the system, and they're all the same (as in same over-heating code affecting 3 valves, due to a bad water pump). If it costs 80.00 just to diagnose EACH Chevy light code for a similar situation, you've paid $240 just so they could go, "Oh, I need to see if the Water pump spins," Then reach in and see what's going on. That kind of garbage ticks me off. And the code systems are such that you can simply google them. Ain't that hard to diagnose most codes... an HOUR of labor per code? LOL That's funny.
However... the dealer's gotta make money somehow!
It's like the folks who take their computer into Best buy to have them install memory for $40. It literally pops into place with a thumb push. It all comes down to what folks who are unfamiliar doing, are willing to pay, so they don't have to become familiar doing it. LOL

OH... Beauty of a truck, BTW! That thing is gorgeous!
