My brake light and ABS light keep coming on in my mega. We check the DTC with the smarty and it states no codes. We reset the codes and lights. The brake lights and ABS lights keep coming on at random.When the lights are on and we try to put it in 4x4, the 4x4 light flashes and the 4x4 won't kick in and won't work. We are pulling a trailer across the country. We can't seem to find anything wrong with the trailer wiring.

'06 Mega Laramie six speed, smarty, big clutch, big tires
Any ideas?

 

Go to your nearest Autozone and have them test the batteries. When they start to go bad, all sorts of strange things start happening.

 

i have a 06 mine doing the same thing but the speedometer wont work either, the told me i have no power to the abs module definately sucks ,, kinda weird i think the smarty is doing something to the ecm causing al kinds of problems
