Code: Select all
hex binary state
86 10000110 idle
46 01000110 status
4E 01001110 cc on
56 01010110 cc off
66 01100110 remote charge
From the highest bit: idle, VCM wake-up logic line status, remote charge, cc off, cc on, unknown, unknown, 0. The unknowns could be 12v supply voltage voltage ok and "within cell coverage"
Since that time I've never seen anything other than these states. You could unplug the TCU and try sending some other things like 0x67: 01100111 and see if that turns it off. However, I doubt Nissan would have left this functionality on the table. The only thing that I think they might have left on the table is the code to change the remote turn on temperature. In the 2013+ models this is a command from the AV unit to the climate control computer. I haven't isolated the message on a 2013 but I suspect it *might* work on a 2011 or 2012.
You might look at EV bus message 1F2. I suspect commanded charge power is in here.

This OBD2 reader has an on/off switch, but i don't know how long it will last, so I am thinking of a switched extension cable.
I was looking at the Tonsiki cable (http://www.amazon.com/gp/product/B00UR5 ... ISFXR1Q6M0) but I read the details and saw that it only passes through pins 2, 4, 5, 6, 7, 10, 14, 15, and 16.
I read a nice report here (http://digitalcommons.calpoly.edu/cgi/v ... text=cpesp) that says the EV CAN bus is passed through pins 12 and 13.
Does LeafSpy use the EV CAN bus? (I can't see how it wouldn't!) Does that then mean that I need to find (or make) a switched extension cable that carries pins 12 and 13?

I read through the google docs spreadsheet of CAN codes and have gotten through half of the 44 (ouch!) pages of this topic in the forum and have found only a dribbling of these codes (about 7 so far). I'm not sure of the exact terminology for these: polling codes, request/response codes, PIDs (Parameter IDs). So not knowing the official terminology I'm not sure exactly what to search for.
