Hi, I have a the electric hydraulic power steering pump EHPS from a W221 S-class. But I don't have an S-class, does anybody know how to figure out what these pumps want to receive on the CAN bus to start pumping?

I would need a working S class with this pump to make a trace, but most owners won't like that. I am also sure this part is on its own CAN bus but not on the main OBDII bus

The pump part number is A0016240

Thanks in advance
