Fuel Pressure

Took our coach 2003 Allure/ 370 Cummins to the shop for annual check up. Just a few minor issues. Next day I went to Costco to fill up with diesel and went through the normal start-up, checking silverleaf for any issues. At first none were indicated, but then this appeared, id fmin description. Underneath these letters in blinking letters were the words, inactive fuel pressure/Change.
I called Cummins and ran it by them. They asked me if my check engine light was on, I said no. Then asked if I had any problems with starting the engine, told them no issues. Any hesitations, none. Then they asked if there was a prior history involving the injector pump. Told them it had been changed in 2007, by the previous owner. So they said that because the SL readout was inactive that I shouldn't be concerned. Well I am. We're getting ready to head south and I don't want an issue to crop up while on the road.
So is there anyone who can help me with this reading? Thanks, John
