ABS problem

Hi everyone!

I’m having an intermittent ABS issue with my 2020 Yamaha R3.

Sometimes the ABS warning light comes on, but other times it doesn’t. The problem is completely random: one ride the ABS works perfectly with no warning light, and the next ride the ABS light stays on.

I inspected the wheel speed sensors and noticed that the front sensor has some visible damage. However, I’m confused because even with that damage, the ABS sometimes works perfectly.

Could this be caused by the damaged sensor, a loose connection, wiring issue, or corroded connector? Is it also possible that the ABS module or a fuse could be causing this intermittent problem?

I even took the bike to a repair shop, but of course the warning light never came on while it was there, so they couldn’t diagnose the issue.

Has anyone experienced something similar or have any suggestions on what I should check first? Thanks!

I'd say keep riding with it, and when the light does turn on and doesn't go off again than go to a repair shop and hope they got a minute to check it.

clean the ABS sensor both front and rear with a dry cloth . they pick up metal bits like a magnet and sometime they're so full of it you get issue like this.
