Power Seat as built

This is exactly what I needed to see. I have all of the info I need except for the "Module Communications Network". I'm assuming that ties into the switches at the center console, but then again maybe not. The switch communication would be a simple input, not an MS-CAN+/i network.

So most likely the Module Comm lines are for the BCM?

I am greatly indebted to you for your help.

here you go:

View attachment Module communication network.pdf

View attachment Climate seats operation.pdf

View attachment Climate seats diagram.pdf

that should be the missing links...

Any progress here?

@buzz-dee your diagrams are treasure, thank you so much!

I'm looking for adding memory to premium (or even base) seats. It is not entirely clear from diagrams: are motors in memory and non-memory seats different? If they are, is it possible to replace these motors and what part numbers are?
