2020 Sportsman 570 Brake Lights stay on

Hi everyone I'm new to the forum. I have a 2020 sportsman 570 I have a issue where the Brake Lights stay on as if I'm on the brakes. I bled the front brakes to try and maybe release some pressure if that was causing it. It didn't seem to help the issue. I found the manifold where the pressure sensor is at for the brakes. I can't reach the plug to pull it out and I'll have to pull off the front end plastics. Is there anything else that can be causing this issue? I really don't want to remove the plastics If I don't have too or take it in for a service if I don't have too.

Same issue. I got 2 brand new 2022 570s. One has this issue. The brake light stay on and after some driving you start getting messages to release the break. There is no drag. Brakes work excellent. I found a sensor behind foot brake, if I disconnect then no brake lights at all. If I play with plug the lights work correctly until I drive for 15 mins.

Look like I'll need dealer service which is 2+ hour drive.
Same issue with my 2022 trail. Ordered an new switch to try but pulled a tad on the master cylinder plunger and the issue went away for a day then came back. Brakes are not dragging. Tried draining some fluid and cracked the bleed valve. Same issue. Going to replace the switch tomorrow and try it.
Hi, did you solve your broblem? I bought 2022 Sportsman 570 Trail week ago and on my first ride "release brake" massage poped up with chek engine light. When I disconected rear brake switch all massages are gone, bit quad stoped start, evend didnt crank.
Sorry, I haven’t been back in here in a bit. I did resolve my issue. I replaced the switch and the issue has not returned for 20 miles. Unfortunately I had to do it at my own cost because of timing and I couldn’t wait for the dealer to be available. Others have said that they got it done at the dealer and it’s a known issue. I suspect it is known because most places didn’t have the switch in stock. In order for the atv to start, you have to hold the brake while cranking. That’s part of the reason I figured out I had an issue, I could still start it without Hilti g the brake. I had to ride it that way for a little while with the messages coming up, but the engine never went into a derate Mode.
