I think the leaf spy app shows what can be done. It only uses standard OBDII, with just one can bus. It could also be using the other non-can OBDII buses, but I doubt it.

Shame it is not open source, but the leaf codes are pretty well documented now.

Oh yes, there are multiple CAN busses on the LEAF. The standard one, which is where all the data below comes from, an the EV can -- that would require some clever doodads, since both are on the same physical connector -- just different pins.

Robert,

Sorry for the delay in response - I’ve been off grid parenting for the past 24 hours.

I think @Nufkin has done some preparation work, and we have a stub vehicle support file (vehicle_nissanleaf.c), but nothing working yet.

This App shows what can be done:

using just the OBD-II port (I assume all the single master CAN bus, but perhaps also other buses on OBD-II).

I’m very excited by this, and more than willing to help, but I don’t have the car here so am limited in what I can do.

Can you work with @nufkin (and his other half) on this?

You would need some sort of CAN bus decoder (perhaps just an OBD-II dongle, or CAN-USB adaptor), plus an OVMS module and PICKIT for firmware download. If you use MAC OSX, the development environment is simple to setup - for windows there are a few more hoops to jump through. Lastly, a RS232-USB adaptor is useful (but not essential).

Regards, Mark.

Hi,
< ovmsdev-request@lists.teslaclub.hk>

Is anyone working on Leaf support?

I am interested in helping if I can and have started a discussion at http://openvehicles.com/comment/220#comment-220 to capture were we are with the Leaf.
