Re: TIPM replaced ? I think ?
I might be wrong, but I don't think the TIPM is the "brain". I think it is simply the fuse/relay block that is under the hood on the passenger side. I had the "brain" replaced on my '13 and it was inside the dash and required work by FCA headquarters. The dealer took it out, sent it to FCA, they transferred certain data to the new one, and then the new one was installed. The data included mileage, etc.
