When the mind gets bored, it sometimes finds naughty naughty things to do. Naughty guy Troy 🙂
I mastered this puzzle/hack some time ago, which grants me unlimited access to GM Service Information for free. As much as I would like to share this trick with everyone freely like once upon a time, the times have changed and to preserve the duration of this trick I will not.
Anyway. This file includes information for gaining access to GM SI "Service Information" which includes GM vehicle module Pinout schematics, diagrams and other vehicle servicing information. It covers North American, European and other models.
With this file you will gain unlimited GM SI access for eternity or until the hole gets close.
The Information can be found at this weblink below.
