I have an 06 CC SB LBZ with a BOSS v-plow and when I use the plow, lifting and angling, the service brake system flashes up on the comp. screen! I was told to change my ground, I've done that, I was told to unhook my brake controller and change where I fused it into the fuse box, I did that and that still hasn't fixed it. One guy said that there is some computer panel for the tranny that might be bad any help would be greatly appreciated! Thanks everyone!!
