Hey guys i figured it's about time to invest into some sort or DTC reader, as winter starts to hit us full swing, I am hearing more and more about MIL lights poping up. EX: the block heater codes or the MAF MILS do to the fender getting pluged with snow. Now as I don't have enough money for a programer of my choice i figured just to buy a generic code read such as this one http://www.canadiantire.ca/AST/browse/4/Auto/AutoTools/AutoCodeReaders/PRDOVR~0251030P/OBD%2BII%2BCode%2BReader.jsp

Just wanted to know if this scanner will be able to read codes off of the duramax and what your thoughs were towards it. I know it's not a tech 2 from snap on and i know i can't read blance rates but i can worry about that when i get a programer, it's just to give me some peice of mine so i don't have to run to the stealer in the event.
thanks for the help
