The "universal" type code readers are only designed to read PCM codes. The will not read other controllers i.e. ABS, ABM, CTM etc.
Federal law states that codes that can contribute to increased emissions must be able to be retrieved with a universal scan tool. Everything else is up to the dealer whether or not to allow universal tools to access that info. Dodge of course, does not allow such access.
Odds are, especially if the horn/cruise/radio buttons on the steering wheel dont work, you have a bad clockspring.
