      Low-Speed CAN w/ the DIM

      I am doing some playing around with my DIM on the bench, so no other Volvo modules are connected. I am using either my CAN USB adapter or my Arduino and I notice that after being powered on for only a few seconds, the DIM stops sending messages. There are only (2) CAN IDs coming out of it, but they seem to stop on the same number of messages every time, so it leads me to believe that it shuts itself down because it knows no other modules are connected.
      Anyone know a way to keep this alive, as well as the other messages the DIM is looking for?
      I can't find a list of the messages that are used. Ironically, I still have some stuff in my own archives for sending messages to the DIM display, which works, but isn't sufficient to keep the CAN BUS alive.

      You still working on this? I came across a few posts of yours on the Swedish forums svxe (i think).

      Check out my github repo.

      I haven't in the last few months, but haven't really stopped.

      I’ve got the code to fully emulate the dim on the bench with just the Arduino and can shield. Try it out!

      I ran out of time right as I was wrapping it up so I haven’t released anything explaining how it all works for a regular volvo enthusiast to figure out.

      I'll check out your git. That's awesome. Thanks for sharing.
      Hopefully this will inspire some others, too!

      Hi. First post on the forum for me. Has an XC70 2003 2.5T AWD. When I have read the car in Vida, I can only read one network, the high-speed network?
      What could this be due to?
      Have no glowing lights or the like and do not find any error codes on the network I can read out.
      Sorry for the translation, using Google Translate. (Sweden)
      Regards Leo S

      That sketch looks good. I'll have to load it up and give it a try.
      Any chance you have the CAN message IDs for the console buttons (like headreset, valey key, DSTC, folding mirrors, etc.) ?
