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.
