My ABS light flashes in this sequence. 5 times, break, 1 time, break, repeat. It used to only do it after it rained, not sure why but after the sun came out and the truck dried up it would stop. but it has been doin it for a couple weeks now without stopping. anyone have any idea whats wrong?

 

Year?

It says "system dumps too many times in 2wd. Condition occurs while making normal or hard stops. rear brake may lock." thats great and all. but how do i fix it... Its hard to explain but i have noticed that when i make hard stops my truck tries to swerve like one of the brakes is locking up or failing, causing my truck to move one direction over the other.. its not a problem when i have both hands on the wheel, but if i didnt my truck would go off the road.

 

If the rear brakes are grabby or locking up thats a possible reason for the code. I would take a look at the rear end and check that the parking brake is free.

 

Chaffed wires? When wet they have a ground. Inspect the wiring from the engine bay down to the abs module.

 

I got a buddy at the ford dealership in town to hook me up with a free diagnostic/inspection for my truck. itll be something just to see if they can point out anything wrong with my truck so i can fix it myself. ill get them to see if they can figure it out. im sure they can.
