Just a note to pass along.......
I am having some warranty repairs done to my '09 DMax and the tech told me there were some software updates out there for these trucks. My truck is bone stock with no add on's or deletes so if your truck is like mine you may want to check with your dealer to get these updates.
As soon as I get the truck out I will be sure to post the details of the updates. I just spoke briefly with the service manager and he indicated to me they were doing this.

hmm.. wonder what it's going to change..--

So did you ever find out what the updates where.

I sure would like to know too, my dmax goes in tomorrow to have the center roof lights fixed.

Any update here? Us 09 guys are curious.

Well, I got the truck back yesterday ( over a week in the shop) and the repairs were done. As for the updates they did not indicate them on my receipt and the tech and sevice man were gone. I will have to call.

As for the cooler tube, that is an upgrade also. The entire tube and rubber hoses were replaced with a different designed tube.

They just did a software update on my a/c. It would quit working and go back to normal after a shutdown of the truck. Very random. Seems to be working fine now.
