ABS light issues

Well the results of my 52 mile ride home from work at 72 degrees, ABS light was on for the first mile or so, then off the rest of the way. So light off and didn't come on at all for about 50 miles. And yes ABS does function keeping rear wheel from locking when I purposely tried to lock it up.

Is it possible that when you jumped the fuse, you spread the terminals that the fuse goes into too wide and now it is making intermittent connection?

That is certainly possible. That area expands when warm and makes better connection.

Good to know, I have never ridden with the plug under the seat jumped, but have jumped that plug many times to check for ABS codes.

The thing is that even if the ABS connection was intermittent...once the abs light comes on, it will not go off until you cycle the ignition key and after the self-check everything is ok
Unless the ECU loses power for a short period of time, and performs the self-check again, and again, and again…..
A loose contact usually causes strange failures (someone in the forum had the battery terminals very tight, but the upper cables were loose and had failures while driving, without the engine stopping)

Grrr!!! My ‘12 is suffering this too. It’s been rained on quite a bit. It had a really worn rear tire, worn rear pads and damaged the rear disc. The abs light was intermittent. I chocked it up to the worn tire. I replaced just the rear tire, pads and disc, cleaned everything up. I tugged on the wheel speed sensor wire a bit trying to reinstall it, I had the hub wss housing rotated incorrectly.
I put it all back together and it seems like the light comes on much quicker and stays on. I’m at a loss for how to fix or diagnose this issue.
My bike was off the road for a while due to bad fuel pump. I have a Chinese replacement.
Recently I had some no start conditions with the 19 error code on dash, seemed to be corrected by cleaning the ignition switch but this could be a contributing factor.
the battery could be sus due to the bike sitting for a while.
It’s also been rained on for the past few years, although it was never really a problem until now.
I’m in the Cali Bay Area and would love to get some help or work with others on this issue.
Hope to get it fixed asap

One thing I'll add is the abs light does go on and off a few times after start-up and moving around. I first noticed it going on and off when riding on the freeway, if I was moving fast it would stay off. Now it is more consistently on. It will cycle more then once when first moving but then it stays on.
I cycled the key off in neutral going down a hill and it seemed to stay off for a longer period of time, but ultimately came on around 25 mph or so.
I'll be checking the front magnet ring today. I pulled the sensor and it looked ok but I didn't get to check the whole ring.

I checked those two connectors, they were tight. I took the bolts out and checked the connections, they were very clean, no sign of corrosion. Reinstalled bolts.

Excellent point, I forgot that. When I had the ABS switch, or really even before I would turn off ABS, light would come on, and stay on until the key was cycled. To be clear, if I turn my ABS switch off, light comes on, ABS doesn't work. While riding turn switch on, ABS light stays on, ABS doesn't work. My bike doesn't work that way now, ABS light comes on/off at somewhat random times, but will go off without cycling the key.

I'm planning on getting some magnetic field viewing film to place over the rings and see if there are any damaged lines on the rings. The bike was rained on quite a bit over the last few years, and quite a bit this winter so I'll give that a shot.

Latest test, after doing two things as suggested above, removing/reconnecting the two connectors circled above, and removing the fuse and twisting the connectors a little to make a better connection. 55 degrees, light was off from the get go, only blinked twice in 3 miles. ABS works as expected keeping rear time from locking on dirt. Thanks everyone for the tips. Not certain which of these two things did the trick, but something did. This short test tonight isn't really long enough to say much, further testing will be needed. As weather permits.

Sounds like you have a lot going on with the bike. You can read what I have done recently. Start by reading the codes of the ABS. Mine initially had a few, I cleared them, they didn't return. I think if the light goes off, and stays off for a bit, there are no codes.

How did you read and clear the abs codes?

The observation that the ABS still blinked twice makes me think there’s still some underlying issue there. The light should never blink or be on outside of a malfunction or the startup self check.

Good point, I don't honestly know if my issue is resolved or not. But I have had better results as of late. My ABS light was on for months and thousands of miles. With Winter, and life stuff, I wasn't able to really dig into issue until recently. Replacing the front tire did not resolve my issue at first, but doing short rides to test didn't show the weird symptoms right away. How the temperature and engine RPM effected the light certainly was strange.

There is a process documented on the forum here, and also in the service manual. Basically to read, find the connector under the seat, jump two wires with a paper clip, turn on key. ABS light will blink. Record the blinks, write them down. Check the service manual for meaning of the codes. If the light just blinks a constant steady rate, there are no codes. I didn't see this in the manual, or on any posts (or I missed it). If there are errors, there is a process to clear the error codes. Re-read to see if you get new errors. You can also test/spin/cycle the ABS pump. This will confirm if your pump is working or not. Sorry don't have time at the moment to post the links to other posts, or pictures of manual. Good luck.
