DTC codes.. mass confusion
 

im gettin a list of 4 codesfrom my programmer.. c0035, c0040,c0055 and b1025... i think theC ones are my speed sensors but i dunno why those would go out but im getting 2 different answers for the b1025... the first plaCe i looked said it was an audio output 1.. that would explain why my speaker in my drivers side door aint workin.. the other explination ive heard for it is driver deployment short to voltage and i guesss that would explain my service air bag light coming on... im confused... help..

The wheel speed sensor codes sound like it may be related to the electronic brake control module.

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

what would i do about my brake control module?? Dealer problem?.. or is it somethin i can reset?

Well the fact that all speed sensors go ut at the same time leads me to believe that the problem is something other than the speed sensors. And the rear speed sensordoes not accually exist in these trucks. ThePCM 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
