Judging from what you just described it appears that you have good voltage to the solenoid but don't have ground coming from the ECM when commanded by tech tool to enable field service mode. I would verify the c17 pink wire (ground) from the ECM at the ECM connector to see if it is resistive or open and then test continuity on that wire from the ECM connector (C17) back to the PTV solenoid. After all this testing the only thing left is the ECM.
