[Ovmsdev] Activating a sleeping Gen 1 Leaf

Quick update,

I contorted myself into the driver's foot well of my right hand drive 
Japanese domestic manufacture 2012 gen 1 Leaf and unplugged the TCU. I 
can confirm that connecting pin 1 (battery +ve) to pin 11 (EV System 
Activation Request) causes a beep from the front of the car and a few 
relay clicks. I didn't try to activate climate control to confirm that 
it works, I'll try that later this week and if it does, hook it up to 
the OVMS. Splice into the loom in the cramped conditions under the 
dashboard won't be fun. I wouldn't be totally surprised if the TCU does 
the charge timer wakeup, so preserving the existing circuit is a good idea.

http://www.mynissanleaf.com/viewtopic.php?p=438109#p438109 says the Gen 
2 Leaf doesn't need this circuit, and the same source describes CAN 
message to do the wakeup. If anyone wants to test that I can add that 
message to see if it works.

Has anyone seen a message on the EV CAN Bus that would distinguish a Gen 
1 from a Gen 2?
