Code 65

I ran a KOER check today on my 91 F250 with the E4OD, and got a code 65. I've heard that there's a specific way you have to do the test or you'll get this code so I'm guessing I'm probably doing it wrong, I just cant seem to find the proper procedure... Can anyone clue me in?

Service Code 65 indicates that Overdrive Cancel Switch (OCS) is not cycled between the engine ID code and the "Goose Test" in Key One Engine Running Self-Test.
