no rear fog from the factory, and changing byte 18 is supposed to clear that up (that's why there is a rear fog option and non-fog option). i think i'll just change it back to 22 and hope for the best. if it is still on then whatever, at least the lights all work and look awesome lol.
No that’s not correct! If you have a fog from factory your coding will be for rear fog and if you don’t have rear fog from factory and set it to rear fog but don’t have a fog switch it won’t work, if you started with two back up lights then fit a fog but no euro switch the fog will come on with reverse gear and trigger the error as it is led and there is no code that removes the errors for the backup lights, this I would say is your problem, get a euro switch and you can then code it to except the fog and not put voltage to it when in reverse.
