How does each piece hook up and how do you get the codes?

I had signed up for Cummins Quickserve and understand how to look up the codes.

Thanks for the help

Plug the 9 pin Adaptor into the truck (below stering wheel). Plug the BAFX reader into the Adaptor. Turn on Ignition or start the truck. Turn on bluetooth in your Android Phone or Tablet. Pair Phone to the BAFX reader. Download and open Cummins Fault Advisor. Follow instructions in Fault Advisor and then take a Snap Shot.

When I struggle with this kind of stuff, I ask my Kids or Grandkids for help. Works for me!
It's important that you use the SPN/FMI To Fault Codes search, as the codes from the reader are veh. manufacturer codes, not Cummins Codes. The SPN is the 4 digit and the FMI is the 2 digit.
