The check engine light on my 08 FLHX last night was coming on and going off randomly. I checked and found code P0572 (under the first P). I found a code P0572 on a search on this forum to mean Brake switch low. Anybody have a clue as to what I should be looking for? Everything on the bike seems to be working. I haven't checked brake fluid levels but I have no leaks.

 

On second look, I have no brake lights from my foot brake. I'll check the fuse first. Where will I find the switch for the rear brakes?

Should be at the back of the engine/trans. down low on the right side.

 

Below the transmission side cover on the right side sitting just on top of the frame rail

 

Update: Brake fluid was low. Topped it off hoping for a miracle. There were no miracles to be found. Tested the brake light switch and it was bad. Also small amount of brake fluid seeping from the front of the switch. Looks like a new switch is in my future. Thanks for all your help!

 

I know this is an old thread, but I had this happen to me yesterday. The fix was that the 15 amp Accessory fuse had blown. After replacing the fuse and clearing the code everything worked like it should.
