Disabling the ABS (2015 + RoadGlide)

I'm not here to argue whether you should disable your ABS system or not. But, if you want to, or NEED to (my situation for safety reasons), this was the easiest way to have your bike resort to the default brakes and bi-pass the ABS (for free and little work).

The reason I had to do this, was because I had complete ABS modulator failure. When I stepped on the foot brake, all I got was solid pressure and a rapid pulsating from my brake pedal; along with complete brake failure on rear brake, it also caused my front left caliper to drag for the first 1 mile until the system would realize it wasn't working properly and automatically disable the ABS. The problem was that a mile down the road with a dragging front caliper and little to no brakes made for a super sketchy ride. What I needed to do was have the ABS shut off as soon as I started riding it so I would have brakes and not have to wait for the automatic ABS override to kick in.

There is no ABS fuse (2015+) that I am aware of. But, if you go under your right quarter panel you can find your ABS module system. To the left of the system you will see a big power connector that connects the ABS to power but also to the brains of the bike. It is the biggest plug that connects directly into the ABS module and you cant miss it. Disconnect it, zip tie it up, and tape off the ends to avoid moisture and your bike will resort immediately to the brakes most of us grew up with. The only thing that it will affect is your ABS light will remain on.

My ABS has saved me multiple times, but has also almost gotten me killed multiple times since it began to fail. I only did this because I was on a 1,000 mile ride and needed my brakes to work reliably to continue the ride, get me home, and ride the bike to the shop to repair my ABS. I did about 1500 miles with the above set up and had no issues. I just wanted to put this out to anyone that is having ABS issues with their 2015+ and can do this at least to have reliable brakes until they replace their modulator. Harley built a s*&% modulator and that is why some of us got that letter in the mail saying we should "change brake fluid every two years, and o yea... Harley is the only ones that can electronically bleed them for 150.00 bucks" (I have literally never flushed fluid unless changing calipers). The old system never had an issue with that but the new modulator is garbage and instead of them fixing the modulator, they want you to flush fluid. No other ABS system on the market (car or bike) has this issue.

I cant post the link that explains the ABS failure much better than I can (I don't have enough posts), but, I am sure many others will have the same issue soon and if you want it just message me and I can send it to you.

I couldn't find anything on disabling a 2015+ ABS (because there is no fuse to pull) across the internet and after talking to a tech and trying it out and it working flawlessly, I figured I would put this out there...

Cheers!

Do you know what caused the failure? Also, I don't know what dealership is charging $200 to bleed the system but they are charging too much. I've see $100-$125 from numerous dealers.

Interesting. Presume you mean front.

If I'm not mistaken, brake fluid flushing guidance is pretty standard across all vehicles. I know its part of the maintenance schedule on my 2013 535i, for example.

Yea my bad, typo... on the calipers. But, a system that is "sealed" no way in hell needs to be flushed every 2 years unless you park it in a swimming pool...

I don't agree but that's just me. The maintenance interval on the brakes is very well explained in the owners manual and service manual and I really don't see your point completely in bashing the MOCO for this. If you don't like flushing the brake fluid every 2 years or 50k miles then just buy another brand bike. Oh wait... they have service intervals too so never mind .

Seriously though, if they didn't tell everyone this up front in many places I could see getting upset with them but you know what you are getting right up front and if you don't agree with it then move on to another bike.


One question though, I've never heard that the ABS module is the place where moisture can get in, can you explain how this happens? I really want to know.

Truthfully, I am just here to help people get there bike's brakes to work in a bind and not debate opinions (I could care less about yours).... I literally just joined this forum so when some poor sob is searching how to unlock his rear and front caliper to ride, this will pop up... Cheers.
