FWIW: I have an '07 GMC. I have a friend who owns a brake/alignment shop. He states that some of the '07 GM trucks are hard to reset even with his $300+ tool. I had tried mine multiple times and not gotten it to work. He tried it a few times and could not get it to work. He sends them to the local Chev dealer who resets them with better equipment and charges GM, regardless of Chevy or GMC. So--it may be the sensors they used for some period of time. David
