Help with this ElectroHydraulic Power steering pump?
Posted: Mon Apr 01, 2024 10:56 am
Does anybody have a vague idea on these Electric Hydraulic Power steering pump?
It is already installed in a broken EV van.
It is CAN bus controlled. All the black boxes in the van (which don't get into drive state) actually are sending something to this EHPS pump, but nothing is happening.
The orange/white combinations are both CAN bus, but they don't seem to be redundand. Because on one of them nothing is sent, and the other is quite busy with traffic below.
Nothing is coming from the EHPS, this is all being sent to the EHPS by the control units in the van (which are not in a drive state)
I tried sending it these messages myself at the same intervals, and changing some of the values, but nothing happens.
It would be great if I can get this unit working, otherwise I have to replace it with some dumb pump.
I don't expect anybody to know how this thing works since there is no info, but maybe somebody has a suggestion on how to continue from here.
Thanks in advance
