Quote:I'm curious how you got on with this, have you continued and found a solution to get these to run? Just working on a similar project with some V60 Inscription Pro seats I have found, and struggling to get them to activate without diving into CANBUS (Yet!)
It's not that simple. When the car is unlocked and the ignition is turned on, CEM sends wake up and configuration messages to all ECUs in the comfort body CAN. Each ECU listens to unique message ID. Those configuration messages includes the enabled options for each ECU such as massage, seat extension , lumber and side supports and etc.
CEM sends those messages configuration messages every 10 to 30 seconds but the ECUs listens to those config messages only during bootup. I guess, sending every 30 second is just a fail safe incase the ECUs restarts due to any issue.
So, you will need an arduino card or similar to send those messages.
I enclosed the messages from my car that has massage, extension, memory, 4 way lumber and side support seats. Even though your seats do not have some or all of them, it should wake up and you should be able control your seats.
