Can anyone ID this network protocol?

Got this off an '07 Nissan Altima. It's from a single wire network shared between all the door actuators for the automatic HVAC system.





Kind of a cool pattern, once you study it for a bit. :lol: Every 'message' starts out with a 11V (tall) pulse, then three 7V (short) pulses. Then the message proceeds from there.

Anyway, just curious if anyone else has seen this kind of pattern in use anywhere else. :blink:

Hmmm, All-Data just calls it a LAN. The system diagram is just as you say, a single wire between all actuators. It is an interesting signal.
