I can not find "step 5" in any of the original K-line manuals I have. I suggest doing the procedure but skipping step 5 listed above and see if that helps.
Also, the "Steam Locomotive Instruction Sheet" that specifically states "This engine is equipped with K-LINE Cruise Control..." states to press "4" to return engine to factory program settings. Nothing about "7" because of the cruise feature.
