I have a 2018 Freightliner Cascadia. I am getting a fault code on the diagnostics in the SSAM. It is, “521300 6 trailer marker lamp current above normal”. My markers lights are not working, but the rest of the trailers lights do. If the truck sits for a night the lights will work for a few minutes before shutting off or sometimes hitting a good bump in the road will make them flicker on and off.
Any help would be greatly appreciated.
