I have no solution, but i'm also interested in a workaround. Does somebody know what connector this is? I only have the actuator without the connector.
I had no time to work on it yet, but the service manual is really helpful!ps - @julwaech did you have any luck?
I had a look and it appears the standard rotation is around 30 degrees.Mathew,
My guesstimate is that it just needs to stop, maybe after a short rotation. I had about 120 degrees of rotation on my temporary fix and the OEM setup looks like a bit less than that.

@InductiveJon - I have ended up using the Resolve Controller - which does not need the parking pawl - see EV conversion kit with Nissan Leaf parts (used) | Resolve-EVI am working on a design for this that uses a small waterproof linear actuator with internal limit switches. Basically you apply 12v in one polarity or the other to lock and unlock the parking pawl on the Leaf motor. It's a bolt on solution, but it does require re-use of the splined adapter from inside the original actuator.
Is this something anyone else would be interested in?
@InductiveJon ... yes would be very interested in this as we are reusing the LEAF gearbox and are keen to use the whole P-brake system, but we don't have the LEAF VCM. The encoder in the actuator talks via the VCM so we need to bypass this. something like the linear actuator you descibe could work.I am working on a design for this that uses a small waterproof linear actuator with internal limit switches.

well, reading that PDF posted above... it looks like this is similar to a brushless motor where the sensors in the actuator are just sending pulses back to the nissan factor VCM and then it is controlling currents to individual coils to drive the motor to specific positions/speed. So unless someone has figured out a way to make a mini controller for this motor, it sounds like the only other alternative is something like @InductiveJon was proposing where you replace this motor with something simple that you can control from whatever logic controller you make to detect when people hit a "Park" button and also look at motor speed and whatnot to make sure it is safe to engage park or disengage it. That's just my current thoughts so far.Wanted to revive this old thread. Has anyone managed to figure out the pinout for this gearbox park actuator / motor? I'd love to be able to drive it (even if manually at first) and understand if it is talking on the canbus or if it just wires indicating limit switches, etc. Anyone have any info on it? The part number we have 33251-3NF0A. Any help is appreciated!
@lordmundi - I have a spare if you would like itwell, reading that PDF posted above... it looks like this is similar to a brushless motor where the sensors in the actuator are just sending pulses back to the nissan factor VCM and then it is controlling currents to individual coils to drive the motor to specific positions/speed.

thanks. a spare of what exactly? I have a working park actuator motor (the original from the gearbox), just don't have any way to drive it. Did you wind up using a different mechanism?@lordmundi - I have a spare if you would like it
