Does the code reader power up? If not, check the fuses. OBD II ports supply power to the code reader. Typically GM uses the cigarette lighter fuse to power the OBD II port on their vehicles (could share a fuse with somthing else, but I doubt it). Good luck!

Not sure, I would try with an OBDII scanner. Available at autoparts stores or online at JCwhitney. Good luck.
SOURCE: oil leaking into cooling system but no coolant in
Looks like a head gasket failure. Oil is escaping out of the engine and within the engine into the coolant passageways. The oil pressure system is run at higher pressure than the coolant pressure and fortunately this has so far kept the water from entering the oil and crankcase. I have no faith at all in any after-market product that claims it can repair leaks by simply adding it to the coolant or oil and taking a head off is not a trivial task. It may also be that the head has warped (this would also cause the leak) and this in turn will require it to be re-machined. Head gaskets are not expensive but due to the work involved this could be one occasion when a visit to a machine shop is the best option.
