If all of the circuits on T-One Vehicle Wiring Harness part # 118265 for your 2015 Honda Pilot have suddenly stopped working then that leads me to believe that the black module box has shorted out and needs to be replaced. Unfortunately, the module box cannot be replaced separately so your only option would be to replace the entire wiring harness.

I don't have any pin out diagrams for the above harness but I am confident the module box has gone bad and it must be replaced as it cannot be repaired. When you are installing the new model box, be extra careful to secure this properly so there is little to no movement as that is usually what causes them to fail.
