Specifically, communication between engine and dash gauges.

The dash and gauges, ABs and other vehicle things all communicate on canbuss #1 network.

The DPF, EGR, turbo, etc.. and other engine specific things communicate on canbuss #2 network. A completely separate network.

if canbuss #1 network is acting up due to something shorting out, etc.. then the inbalance could be seen by using an oscilloscope while its acting up.

Like last time, it’s back to normal after about 2 days. I’m thinking rubbed wires snd moisture. But look at all these counts of ABS controller and 1939. Which causes the other? Is it most likely an ABS problem? I thought it was the other way around.

(My lower radiator clamp broke and I lost all my coolant. That’s what all those are about.)
