What service to perform?

[ths55]

On start-up my 2014 shows a message, "perform service". I plug in my code reader, but it doesn't show anything. Any ideas?

How many miles on the truck? If you are at 67.5K it is time to replace the Crank Case Ventilation Filter.

That's exactly what it was on our 2012 when it rolled 67k....

My truck has about 112K, and I have not replaced it. It had 36K when I bought it, and I imagine it is unlikely it had been replaced before then. Thanks all for pointing me in the right direction.
