2015 RT Cruise Control Failure

Had the bike in the shop today for the Cruise Control not working. Checks with the computer diagnostics showed not issue. Problem was chased down to the third brake light which has been installed since it was new. Anyone else had this issue.

Which third brake light do you have and do you have the run/brake module? I know of a few cases on 15’s where the Custom Dynamics High Mount Brake light wth the run/brake feature caused odd errors to come up. Removing the run/brake module and using the light as a brake lght only cured the problem.

Edit: Custom Dynamics calls it a Dual Converter ‘to convert to a dual function run and brake light’

I do have the custom dynamics run/brake module. Thanks for the info

That module is easy to take off. I hope it fixes your issue, that was all it took to fix our friends.

When I first got my 2014 RT, the cruise control would go out everytime that I took it in for service. It would seem to stop working every time they put it on the BUDS system. But after about 500 miles, it would start to work again. This happened for the first 3 services that I had done, and never gave a problem afterwards. Never did know the reason.

Sometimes an aftermarket run/brake light will bleed voltage back through the brake circuit and make the cruise control think the brake is applied. I had this happen on a bike and installed a diode to cure the problem. The diode only allows electricity to flow in one direction.
