    Dodge Ram 6.7 2011 ECU does not answer after trying for read.

    Good day!

    It's my first message.

    I have a problem - after trying to read ECU on Dodge Ram 6.7 350 2011 - engine does not start.

    I read this DTC's
    U1601 - Restraint system dedicated bus #1 malfunction (Suppression system bus). ABS
    C2206
    C2202
    U0100
    U0141
    U0102
    U0415
    U0100
    U0141

    What goes wrong? Please help me.

    I just got my new MPVI2 this week for my 2011 RAM 5.7 and I get the same error about 3/4 the way through the scan. Did you ever get a solution?

    Thanks.

    Did anyone ever get any assistance on this? I just had the same problem when trying to read a 2010 Dodge Ram 3500 6.7L Diesel. I did not try to write anything to the ecm, only tried to read and it failed part way through and now the ECM has no communication. I had to pull the ecm and hook up on the bench to retrieve code U1601.

    Isn’t there a thread in the diesel section about bricking dodge diesels by trying to read em w HPT?

    I don’t do diesel but I heard no one is plugging a 2 or 3 into a dodge diesel bc of this

    Heard it from more than one person

    I found out, yes, the ecm is done for. I'm sure there are other ways, $1800 for ECM and stock flash. There are no warning signs. IT WILL BRICK just by reading.

    It's not just 2 or 3, I used MPVI1.
