what does code 121-12 mean
Where did you get that code, it's not an engine management code or an ABS.
engine code is 4 digits, ex. P0300

Had to go to the Actron site. 121-11 Vehicle Stability Assist Solenoid Valve Malfunction
So, that means it is a generic type code and not vehicle specific meaning that to get the code you would need to have Honda read the codes with their equipment, or get a Honda Manual specific to your vehicle, or just start the search via any Honda Repair forums for your specific year. Hopefully someone here will read your post and know what it means.
Yes it is generic., and was only accessible through the scanners web site, and that in itself is strange. A better scanner would most likely be more specific, especially if it did do vehicle specific and also ABS and SRS.
@tennisshoes- I have had both good and bad luck over the years with many scanners, including 3 different models of Actron & Mac Scan Pro. Some worked great on some models and crap on others and also vice versa. It is only the basic generic standards that most of them meet, unless you are career mechanic or die hard car devotee, the extra funds for top level stuff is a hard stretch. Very unfortunate for the everyday enthusiast who runs multiple cars as I do (currently 5) and does their own repairs and rebuilds except for trannys. I especially love it when they tell you INCLUDES and your vehicle(s) are specifically mentioned, only to run the codes and get the BS message for a generic code and followed by see vehicle service manual.
I believe most of us on here are, or were career auto techs. If your running 5 late model vehicles maybe you better think about getting a really good live data scanner with freeze frame.
