I recently installed a new (to me ) OBC recently installed...
It now tells me "TAIL LIGHT FAILURE"
my Tail lights are stock. They are all one, brakes light up, reverse lights light up, the far outside part of the light doesn't but I am told that is a optional light
Connections look good, lights light up and I replaced nearly all of them today just to see. Other ideas?
