    Default Lean cruise .cax file for 05120003

    I was hoping to enable Lean Cruise on my 2005 2500hd, but couldn't find a .cax file corresponding to my OS. I'm running COS 3, with an OS number of 05120003. Does anyone have the .cax for this? If so it would be greatly appreciated!
    Thanks!

    You know with the Custom OS3s it is not necessary to use the Lean Cruise .cax , the COS3 has the ability to simulate lean cruise .

    There is no LC .cax file for 12592618/05120003.

    Hello smokeysbandit,

    I’ve never had occasion to use a Custom OS, and know very little about how they work. Custom OS 05120003 appears to coincide with OEM 2005 OS 12592618. I do have a LC *.cax file for the OEM OS.

    For what it’s worth ……

    Regards,
    Taz

    Thanks Taz! I'm going to have to give that a shot when I've got some time.
    Take Care,

    This was the original group of .cax files that turned up, they may have been obsoleted by what others have been working on.

    Hello Highlander,

    I inadvertently deleted a bunch of attachments a while back - my apologies. What OS are you using ? Will post the corresponding LC *.cax file (if I have it).
