I have also tried 5V+ to Can_H and 5V- to Can_L. Still no movement.






Anyone know how to get the drivers module to wake up? All the other modules I've seen are black, mine is white. Is this related to the later model year or related to memory seats? Anyone successfully been able to bench test the memory seats without being installed in a car?

I'm having the same issue. I used a 555 timer with a 12>5 buck converter and can't get the seats to wake up with the white controllers

I was never able to get the controller to work. I ended up transplanting the E34 wiring harness into the seats. Basically just connect the E90 motors where the E34 motors used to be connected. You loose the memory function, but I got everything else working.

Hopefully someone smarter than me figures out a better solution.

Using info from this thread and others, I wrote a thorough (3000 words with pics) DIY for anyone looking to put OG M2 seats in their LCI E92. Some of the info will be relevant for other retrofits as well.
