| Sign of the times hehe.. we've got SAN (storage area network), LAN (local area network), WAN (wide area network), MAN (metro area network), PAN (Personal area network), CAN (controller area network)... and many more!
Let me make this simple.. you can connect your SAN to your LAN via your WAN that rides on top of the MAN, but you can't connect to your CAN without a USB PAN, because the protocols are different.. duh!
CAN is a good thing.. ODB was a good thing, mind you, but CAN is more of an open standard for a robust network that allows ECUs to communicate in electrically noisy environments. The CAN model essentially operates at layer 1 & 2 of the OSI model (physical & logical) to define standards for connectiong, and communicating on the network. It's faster than ODB, and soon you'll be able to just have a USB adapter to plug your laptop into your CAN and just read, adjust, modify, upload anything you want. (assuming you have some software that's able to talk to your Tundra).
The ODB port on the tundra is talking ODBII but it is actually CAN under the hood.. so they're has to be something that's converting ODB talk to CAN for the backwards compatibility. All cars will require CAN in 2008.. and going forward.
I, personally, can't wait!
