ABS on and no rsp for b code
2011 FLHTCU sub 30,000 miles
I need to check the wiring by the triple tree but I was wondering if anyone has had this before. After new wheel bearings and audio system upgrade I have an ABS light that stays on. The light does the normal flash at start up and goes off after riding but the light will eventually come on during the ride and stay on. Constant on, not flashing.
I checked for codes and there are none related to ABS. I have others but they are P codes related to my aftermarket exhaust and the o2 bungs being removed.
However, when checking the "b" section I get no rsp. Run switch is on, WOW tests ok in that the speedo sweeps all the way and all the lights light up. ABS light starts solid and then flashes for the remainder of the test. I cleared all codes and the light came back on after riding a ways and the no rsp still shows up.
Are b codes ever related to ABS? Any idea on where I should be looking? I am going to also post in the audio forum for the audio upgrade part of this to see if anyone over there has had this happen.
My wheel bearings were changed and the bike was ridden prior to the audio upgrade and no ABS light came on during that time.

Check abs wire connector in nacelle/faring. Maybe abs senser wiring harness was stressed and wiring is now bad. People have successfully spliced wiring instead of replace harness and sensor.

After clearing the codes and having the ABS light return multiple times the bike finally showed codes C1025 C1216 and C1095 last night. This morning I cleared them and rode to work. C1025 returned but nothing else. C1025 is front wheel speed intermittent. After I got home last night I checked the plug from the WSS near where I goes into the main harness. The wiring was kind of bent funky (S shape) where it was positioned so I cut the zip tire and for now just have it hanging free. Its still attached to the fender tip lighting wire so its not just flopping around. I unplugged the plug and tried as best I could to visually inspect the wiring inside and leading into the plug. There are no obvious signs of damage.
C1095 and C1216 front brake switch open and rear brake switch open respectively. Anyone know if these are just side effects of C1025? I have never received these codes before and the brake levers and lights operate normally. Seems awfully coincidental these codes show up along with C1025.
I am going to remove the axle and check the sensor itself for any damage/debris but if that checks out do you think I should just buy a new sensor and see if that works? I am not really feeling up to tearing the bike down to get to the main harness and trying to trace a wire... to be honest that sounds like a nightmare.
By the way, when I clear the code the light does not return until after about 10 min of riding. And each time it turned on I was traveling straight.
Oh, one more thing, would you still ride it while a fix is being figured out?

Interference on the WSS circuit
Dynamometer testing
WSS fault or malfunction
ABS ECU fault or malfunction
Incorrect or worn bearing assembly
Mismatched or improperly sized tires
Worn suspension components
Riding over rough terrain
External or internal wheel speed circuit intermittent open
Electrical noise on the WSS wires
Since you say you changed the wheel bearings, the bike was ridden prior to the audio upgrade and no ABS light came on during that time, I'm suspecting the audio upgrade might be the issue.
I would disconnect the audio system and go from there.

I'm looking in the Electrical Diagnostic Manual for my '14 Limited, so the manual for your bike might not show the same thing. These are the conditions for C1025, as well as other related codes that you aren't showing:
Interference on the WSS circuit
Dynamometer testing
WSS fault or malfunction
ABS ECU fault or malfunction
Incorrect or worn bearing assembly
Mismatched or improperly sized tires
Worn suspension components
Riding over rough terrain
External or internal wheel speed circuit intermittent open
Electrical noise on the WSS wires
