    Need help with diagnosing an ABS issue

    There have been some recent posts on another forum by several people who seem to have similar problems to yours that just stepping on the brakes "very hard" while stopped solves the problem. Very hard to some is like slicing almost melted butter to others, but I don't think it would damage...

    Module confusion and issues on my 2008 LMM

    I think that the pin C feeds something for export vehicles (not yours), but also notice that it feeds Onstar. Follow pin C up and to the right.

    Module confusion and issues on my 2008 LMM

    Great buy and likely at a price lower than any visit to the dealer for a diagnosis. And when looking at the waveform you can tell whether your LAN is working or not. Even where these situations are intermittent, it still tells you the story and gets you to the problem module quicker than any...

    Trailer Brakes Too Weak

    Module confusion and issues on my 2008 LMM

    Pretty good video. He keeps it simple and doesn't get into the more complex stuff . I had not previously seen the multi-connector he used to plug into the comb connection, which makes diagnosis much simpler. Our lmm's have 2 communication systems, a low speed, and a high speed. The low speed is...

    Module confusion and issues on my 2008 LMM
