This is a fast and easy way to get EM61 motor out from PARK. (Maybe works just the same with em57)
When removing the nissan assembly, it is possible to just change The P lock with a 11mm spanner.

Here is pictures of the 2 positions it goes to:

D = DRIVE _-_-_-_-_-_-_
-_-_-_-_-_-_-_

P = PARK

This is handy to know.

Has anyone worked out how the actuator works and can control this electrically?

I'm guessing it's just a motor that needs to be controlled by a h-bridge and has a position sensor for feedback?

Hi, yes, it is an SR motor, Switched Relucatant motor and needs a controller that reads the hall sensors in the motor.
I am working on such controller because I need one in my Saab 9-3 cabrio, which has a full Leaf stack.

On the Leaf this motor is controlled by the VCM.

see here the page from the Nissan Leaf book.

Yes it is SR motor.
I have the motor and its controler at home if someone wants to play with it.
First i wanted to use this but since my pug has handbreak i dont need it really.
I thought about using a socket and weld a rod to it. Then with a 12V door actuator i would turn it P D by relay.
But i am happy with park locked open now.

Can I somehow copy how it works from my complete daily driver leaf with em57?

I am now in same boat with arber, that I just leave it open for now.
+ Later work out something if I feel like it.
Maybe use a cable and a lever.
Maybe use the original assembly.

Does anyone know the current required for each phase? Or anyone torn open a VCU to see the ics which drive it?

Also I assume for the encoder it's 5v, Gnd and two signals. Does anyone know which pin is which?

Hi, please check attached picture
