GM Service Manual Inconsistent: error humanum est?
Hello,
In the GM Service Manual, Helms edition, for the 2008 C6 Corvette there is an inconsistency.
In volume 1, section 4-83 it states on the schematic that:
In volume 2, section 11-215 it states on the terminal part list that:
These two statements are contradictory, does anyone know which of the two is correct?
As I am not a GM Dealer, I can't contact them directly to report this issue.
My current assumption is that someone screwed up on the description in section 11-215 and the schematic in 4-83 is correct.
Thank you very much,
Cedric

In volume 1, section 4-83 it states on the schematic that:
- Pin X2-6: is the rear fog lamp switch signal, circuit 1977
- Pin X2-22: is the rear fog lamp relay control, circuit 187
In volume 2, section 11-215 it states on the terminal part list that:
- Pin X2-6: is the rear fog lamp relay control, circuit 1977
- Pin X2-22: is the rear fog lamp switch signal, circuit 187

I don't see a real problem. The signal from the switch can also be considered the control line for the relay. It is inconsistant, but if you understand what it is saying, it still says the same thing.

Anyway I tried it and powered the car up, the first solution is the correct solution. It's typo in the book:
In volume 2, section 11-215 based on my experimentation, it should read:
- Pin X2-6: is the rear fog lamp switch signal, circuit 1977
- Pin X2-22: is the rear fog lamp relay control, circuit 187
