Direct sniff of Leaf inverter using can

Post by TrueSoln »

Hi,
Im playing about with a Nissan Leaf Gen1
And want to see if can direct connect to CAN on the Leaf inverter and watch & send messages.

Got two uno sending happy between then selves using CAN module.
But when I power up the inverter, then I start to get CAN send error on the uno
And not seeing any message coming on CAN bus after that.

Image is what I have setup and the pin out using on the leaf.

Have i got the pins wrong, or need a 120ohm resistor or some thing to allow to connect to can on inverter ?

Found the issue, was using wrong frequency with CAN messages
So when inverter turned on it classed and killed all the messages on the bus

But worth a note to make sure you have correct can terminators when start going longer distances.
For this one I manged to just go shield to inverter plug with out a 120Ohm need at inverter end, actual I would think that would be one on that already
