Maybe Yamae can answer this one. Did the gen 1's use the CAN system? Since there wasn't a lot of interconnect ability on them is why I'm asking. Searching just pulls up nothing related.

see if this will help you out....
CAN was created in 1984 by the Robert Bosch Corp. in anticipation of future advances in onboard electronics. The first production application was in 1992 on several Mercedes-Benz models. Today you will find it on all new vehicles.

Controller Area Network (CAN) electrical systems began to appear in new vehicles in 2003. Since then, more and more vehicles have been equipped with CAN systems, until 2008 when virtually all passenger cars and light trucks sold in the U.S. were CAN-equipped.As a vehicle owner or do-it-yourself mechanic, you need to know how CAN has made the electrical system in late model cars and trucks much more complicated than ever before. CAN allows various modules and systems to share data and interact in ways that where previously impossible.

Yeah saw all the Wikipedia stuff but we all know how not so always accurate that is. And since Lexus was way ahead of the times it just got me wondering. Though the lack of intercommunication of ecu's is what would make me question it. I think ABS / trac and engine trac ecu has intercommunication wondering what lexus used then?
And when was full fledged CAN implemented on Lexus cars?

No, the gen 1 didn't use the CAN bus system.
See the link below and just read the English part for the brief understanding. Reading the Japanese part, you can understand the details.

There was no English, there was arrows saying 404 not found.

How about this below.
Simply click this to access the pages.

Edit: I've tried above and found still not OK. Deleting the characters """ at the final part will make it OK to access.

See the huge bulk of wiring looms in these cars?? There must be 60-80kg of wiring. It would have benified greatly from a CAN bus.
