Default CAN Communication?

I'm just trying to figure out some information, and I can't seem to access Toyota TIS to look up diagrams. From my understanding, the '04-06 LS430's have CAN Communication throughout the modules and the previous '01-'03 LS430's did not. Am I correct?

That's correct... Here's the CAN Communication System Diagram.

Thank you so much for the confirmation! I was wondering, do you have the ECM pinout diagram for the '01-'03?

Dude you are the man! I was about to ask for that. This definitely helps me out quite a bit.. I'm looking to do a 2JZ-GTE swap into a LS430 and sounds like it'll be easier for me to work with a '01-'03 than the '04-'06 because of CAN.
