    Probably just over current in the Jake solenoid circuits.

    I don't see how a cracked egr cooler would cause this.

    Well, if the cooler was cracked it needed to be replaced anyways at least.

    It was code 39. But I dropped the truck back to the dealer today. After putting another 3k on the truck since monday, I hear this annoying whinning sound coming into the cab. They will look at it tomorrow. They should be looking at it tomorrow. I stopped at another place to get it checked out and was told that it might be the EGR valve. Really starting to hate the EGR BS.

    But all the other symptoms did go away and the MPG did go back up to as before.

    Hi all
    I got the same problem and when I stopped using engine brakes, every time I would accelerate, the check engine light would come on and it would sound like a lower scale of engine brakes was on.
    I stoped to check it but after a restart, no more problem.
    I had 4 faults with the two of them disappearing before i had the chance to write them down and the two that stayed on were abs related.
    Truck working fine now
    Any idea?
    Thank you
