J1979 (not a typo)
FluidPowerTom:
Is anyone familiar with J1979, and can you recommend a good document for applying it? I'm finding references to the standards document and some articles about it, but I haven't found anything that breaks down the messages (11-bit CAN ID I think?).
spittet:
I have no clue, but I found this :
https://www.sae.org/standards/content/j1979_201702/
Maybe you could buy this standard (do not cost that much) and maybe you will find the required info.
Have a good day!

Sam, we do own several of the J1939 standards, but I don't think I'd recommend them to anyone as learning material for developing an application. They're more low level than what is needed for a developer using a platform like PLUS+1. They're great for referencing the details of various PGNs and SPNs once you already know what a PGN and a SPN is.

You mean SAE J1979 a.k.a. OBDII? Here's a message and PID breakdown:

https://en.wikipedia.org/wiki/OBD-II_PIDs
FluidPowerTom:
Thanks! Indeed the Wikipedia page was the best I'd found so far for practical application stuff I need, and I used that to build a list of transmissions and expected replies that I'll be testing soon.
I'll scope out the other link and see what I can learn.
