2009 Honda CBR1000RA ABS Problem
I have an intermittent problem with the ABS on my 2009 CBR1000RA. I've owned the bike since it was new, it has 12000 miles on it. The problem started this year. Sometimes after riding 50 miles or so I get the fast flashing LED that indicates an ABS failure. After the failure, once I put the ABS in diagnostic mode, I get a diagnostic trouble code of either 5-1 or 5-3, most often 5-3. According to the shop manual this indicates a problem with the front power unit or air bleeding incompletion. As per the procedure, I did the normal front brake line bleeding. Since there was air in the system I figured that would resolve the problem. I reset the diagnostic trouble code, and once again I rode it for 50 miles or so before there was a failure. Next I tried bleeding part of the ABS system as per the instructions in the manual, I didn't do all of it yet because it requires removing the radiator, etc. This also cured the problem for a couple of days, about 100 miles or so. Before I tear it all apart, I thought I'd see if anyone on the forum has had a similar problem with their ABS and what it took to fix it. Any and all suggestions are welcome. Thanks for your help.
