I was using my Hypertech power programmer to set my new wheel heigth ( 37's ) and it told me I had a DTC and I want to know what it is. The code is: B2355. Can anyone help or send me a trouble code list to print for future reference.
My Hummer is a 2005 H2 SUV with the Magnacharger super charger decked out with headers and cat back exhaust.
