I have 2.9v on the CAN H and 1.8 on CAN L, powered up the Arduino with laptop, shared ground on seat and Arduino, 12v to seat module, absolutely nothing.
You need to have total 60 ohm resistance in the CAN network (between the can H and CAN L).
The MCP board has a 120 ohm jumper on it. Make sure it's connected. On the other end where the module is connected, put 120 ohm resistor between CAN H and CAN L.
The unit must receive a configuration message to wake up and enable the functions.
Thanks IMAY, it actually ended up being that the CAN wires were too short (which I have never seen before, and I just tried it on a whim). I got it all working using a file from one of the guys on here, now the hard part is going to be finding the right seating position, holy adjustments batman!
