well, ok then...

 

Several replies were trying to "teach you to fish, instead of giving you a fish"....

Most people on this forum are always willing to help out, but we don't work for you...

If you're not willing to put in a little effort to learn about/fix your issue, many forum members won't put in the effort either...

 

i did a search then asked a question didn't get an answer

 

Still no reason to get pissy.... Nobody here owes you anything...

I also disagree with you that you didn't get an answer.... you didn't get the answer you wanted, so you chose to lash out...

You ignored several answers about how to find the code, and any other codes that would/could pop up. (teaching you to fish)

You obviously ignored Ssitruc's reply above (who gave you a fish):

"What happens when you clear it, does it go away, or does it come back?
Are you sure about the "c" on the end of it?
U0121 Lost comm W/ABS"

All those answers gave you a starting point to help you to diagnose your problem.... Without further info, nothing more we can do....

There is usually an exchange of information and the more info the better. We are not with your bike and can't see or hear the many minor details that count when diagnosing a problem. We have no idea what you may, or may not have done, prior to this post to trouble shoot your issue. It's very hard to try and diagnose something via a short internet post...

There are often several possible causes for an issue posted by someone... It is rare you will get a short, one-line easy fix for a problem posted on the internet..

For example, with your issue "U0121 Lost comm W/ABS" could be a glitch, could be a bad connector, could be a bad wire, could be a bad sensor, did you do any work around the wheels, did you do any work around the wiring for the sensors, your ABS unit could be bad, etc, etc, etc...

You chose to insult those who gave you info, rather than answer the question by Ssitruc, thus alienating those who were trying to help you...

I wish you luck diagnosing your problem...
