ABS can failure mid ride.

I recognized this three times already. I think optimal way it is caused by "loose" fuses and bad way by "loose" connectors or broken cable.
 
It happens almost every ride, it used to bother me, now I don't care anymore, I got used to it.
When the dash flashes with can abs failure, I still have functioning brakes. So I'm not worried.
Some said it was fixed after replacing the battery with a shido lithium battery, but I've done that and still get the message.
My local dealer had no idea how to fix it. He basically said: They all do that 🤷🏽‍♂️
 
My 701 does it sometimes, I just look if anyone is behind me and then do a quick mash of the front brake one time and it goes away.

My 401 did it everytime I rode through dusty / misty conditions, and also went away with one abrupt braking.

Edit: I have a very big Shido battery in the 701, and had a smaller Shido battery in the 401 also.
 
I guess this happens often on mine also and I just hadn't noticed it before.
I'll keep an eye open for it from now on.
Thank you all for sharing your experiences.
 
It happened once or twice on my bike too. One time I traced it to a low battery, and the other time . . . it just happened and went away, Who knows?
 
It happened the same to me last week on my way to work, ABS, TC and even the quickshifter stopped working (bike went fully "analog" while riding on the highway).

The bike was working fine again on my way home (I had to reset the CEL with the OBD though), so I don't think it was anything loose physically. The error code was a generic "can bus failure".

My guess is that the battery wasn't fully charged (was my first ride on this bike in 2 months), but that's just a guess. There are a lot of gremlins in this bike, let's see
 
Can bus failure is different, and I had that too.

Mine happened when the voltage was low due to some weeks not riding, and right when I throttled around the first corner.

Charged the Battery to full and reset the obd, seems to work now.
 
I have got the can bus/abs failure a few times as well, new lithium battery. Mine usually happens right after a high speed run on the interstate when I am cruising through town. It always clears after a second or two so I just ignore it.
 
Had this issue with my Vitpilen 701.
Bought it used. The dealer told me in advance about the sporadically occurring CAN failure so I got a great deal.
The dealership changed lots of things already for the pre owner and even sent the bike to KTM for analysis w/o success.

The issue magically dissapeared after I got a new rear tire!
I didn't notice the failure so far (drove about 1500 km but also do not look on the speedometer that much ;)).
In an other forum I read that KTM dosen't have a spec to adjust the distance between sensor and sensor ring.
Hence I suspect that if the sensor sometimes is positioned misfortunate to the sensor ring.
So in some cases the sensor deliveres an implausible signal which might get interpretated as an CAN failure by the system.
This is only guessing from my side.
So maybe putting the back wheel off and back on might help?

I dont think taking off the wheel will change anything, the abs disc doesnt change position on the wheel.
The abs sensor does have some play, it is very minimal and it probably is not going to make much differences.
 
Did you ever solved this issue? Mine does this from time to time. I have already checked the battery and the state of health (SOH) is at 100%, also state of charge(SOC) is at 100% after charging it. But, the fault still came on from time to time!
 
I am interested if there is a solution, mine has done that since I bought it. I changed the battery, same thing.
It happens like one or two times per hour.
 
It is caused by moisture in the instrument cluster cause shorts across the circuits.

Bad ground on ….?
Have dealer check modules and or sensors for a poor ground.

I can imagine that this can be the cause. But, since the problem is common, i thought that maybe some owners can specify where to look. Checking all the modules and electrical wiring, can be pretty difficult and time consuming.

Indeed, i did see some condensation inside the instrument cluster, from time to time. I will check this, since is easy enough to take apart the instrument cluster.
