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 ?
