To start off I have a used 2008 lmm 2500 crew cab 4x4
I bought the truck used and it came with a dsp5 switch installed and an autocal in a box from ATP I tried to use the display data option on the autocal to read if the switch was working but I don’t see the E35BDSP5Non-DSP5 or any other option when I turn the switch.
