2008 F250 4-door 6.8L

Feels like the ABS engages EVERY time I brake. Happens on dry roads, wet roads it doesnt matter.

The ABS light comes on intermittently.

Any ideas??

 

if your local auto parts store has a code reader that can read other systems besides the 'regular' ODBII codes [it would generally say on the unit that it can read ABS codes], go there to get the codes read, or get a code reader that is capable of doing it.

Alternately, if you don't have a code reader that can do this, and want to keep your vehicle for the long term, I would suggest getting something like Autogenuity [with the Ford-specific enhancement]. Hand-held units with ABS and SRS [air bags] capabilities quickly get into it's price range, and software like Autogenuity can access and aid in testing pretty much all the computers in your truck. I am assuming that you do have laptop running Windows.

There are other packages that do similar things, but I'm happy with AG.

The other thing I would suggest, if you want to do all/most of the work on your truck yourself, is to either buy the full-service manual or get a subscription at a service like alldata.com, which has the procedures for diagnosing and fixing pretty much everything wrong with your truck. The AG software can even help with some [but likely not all] diagnostic procedures that involve controlling computers to do various things [for example, on my '04 GM 6.0L, it could run the procedure for testing that all the fuel injectors were flowing the same amount of fuel].

 

You need to check what codes are stored and you will probably need to view some live data

 

just ordered the OBD2 with ABS tester...

hopefully that will help.

same thing on my wife's 2008 expedition
