Default Indicator lamp lights help


Was about 10 miles out this morning,running around 60 and these lights came on. Traction control, security/fault and abs light. Trying to find something in the factory manual to figure out what is wrong. Can't seem to figure how to read light codes. Any input to what could be wrong or help figuring out how to read the light codes would be much appreciated. A little more info, bike is a 2020 flhtk with a little over 17000 miles. Brakes have been flushed twice by dealer, the last time black Friday 2024

Hold the button on top of your left handle bar controls and turn on your ignition to get in “diag” mode to see if you have any codes thrown.

Should be able to google the codes and see what they are. The “h” at the end stands for historical, I do remember that much…

It appears that I have a rear wheel speed or abs sensor problem. Also maybe a MAF sensor issue. Not sure about that code because the bike runs find but I'll look into it also

Keep in mind that if you so much as screw around just unplugging lights without first pulling the main fuse it will throw weird codes. I just clear them and move on, but just changing lights won’t light up the check engine light.

I guess what I’m saying is that you might have had some earlier codes stored in there from something simple like changing lights.

If I’m not sure I’ll just clear them all, because if there is a problem they will come back.

I haven't changed lights lately but maybe that could be the MAF sensor code. I'll clear it and check again. Todays issue with the abs is the priority
