In my case I don’t believe it needs to be terminated as it is an active termination. Mind you… it already works now without one (and has been working for over a month now). I also see that you have a MK1 of the Cerbo having a BMS-Can whereas I have a MK2 with two VE.cans (VE.can 1 and VE.can 2). So this is not exactly the same.
Grr… still don’t know why this is. I might have to swap them to see if it makes any other result, or wait for an update of the firmware to see if it gets resolved.
