I may have hit the mother load.
I found a way to access Nissan's proprietary PIDs. They aren't found using the standard mode $01
described here and they are 2 bytes long, not just 1. They are accessed using mode $22, but the ECU needs to be placed in a special diagnostic mode (I don't think this will impact driving at all since the dealership needs to run the car while testing it too, but I still need to try it out). I describe how I figured this all out on my
blog here.
All in all, I found 254 custom PIDs that are completely undocumented so it's going to take quite a bit of work to decipher them all. Please help if you can. Hopefully this will give us access to a lot more sensors and data. I'll be updating my progress on here and on
my spreadsheet. They're on the "Extended PIDs" tab.
Here's what I got with the key in the ON position, but the car not started. It goes PID, # bytes, then the data bytes.
