The kode it's referring to is 466-466 (numeric value). A lot of kodes represented in magazines and verious sources other than the game itself had one symbols represented by a number. It's pretty much unknown how they get the number, but it's not important as there's only 9 combinations (replace the number with one of the 9 symbols until you get the right one). This is what the kode looks like when you input it:
(Kombat Kode not actual size.) This is for "Unlimited Run", which allows players to continuously use the Run button and perform combos without the run meter depleting.
