Please post updates as you proceed with a fix if you would. Thanks.

Yup, had to order the pigtail off of Amazon. If it is the pump motor Harley just discontinued it.

Yeah, I saw the number, I hoped you had looked it up.

I would expect a wheel sensor open code (if that wire is even completely severed) and not an ABS pump motor code, which is what those codes are.

I called the dealer and Harley discontinued the pump motor. I did find a used in on EBay. I guess I may be stuck with a un rideable bike.

Default Shut off
I’m not going to buy used ABS units off of EBay for my bike. I know I’m not going to use the ABS, only issue is the CEL comes on for it.

Is it possible to plug into the ECU to shut off the ABS so it doesn’t throw the code?

Yeah, I’ve read up and watched up on the bypass method. Just nothing addressing the CEL when it lights up because of it.

not sure if you're following this thread below. Would be nice if these were all 'grouped' in one area somehow

Default Well
Well, I took my bike down and my mechanic found the issue. A previous wiring repair came apart that was on the right side near the neck. $80 later and ABS is up and working proper.
