I have a 2001 dodge ram 5.9 gas 4×4 So for the last two are three months every time I go 70 mph in my truck my anti lock brake light comes on along with the other brake light truck runs fine I got all new brakes on it all the way around an all I got to do is stop turn the truck off an back on an it goes away but as soon as it hits 70 mph on the mph gauge sure enough it comes right back I take it to the local dodge dealer an they tell me they can't find nothing wrong

 

You have a bunch of metal debris on your rear end speed sensor OR your tone ring is damaged a little.

 

You should use punctuation because I stopped reading at 70 mph.

Good luck.

 

Longest run on sentence ever.

 

...or the speed sensor is acting up at that speed. It should be throwing a code though, so the dealer should have found that. The "brake" light is a code btw.

 

DAM! You read fast!!
