The code for the lf audio circuit could be a broken, grounded, or shorted to B+ speaker lead. pull the radio and test the leads for a short using a Multimeter _____________________________ If you have a question, ask it in the forums.

And the rear speed sensor does not accually exist in these trucks. The PCM send a VSS signal to the EBCM, and the EBCM converts that signal into rear wheel speed. If you still have warranty on the truck I would take it in and the dealer can fix both problems _____________________________ If you have a question, ask it in the forums.
