NH CX combine errors

[AKA]

Hi my cx combine has recently been throwing up some error codes of which my dealer is not getting to the bottom off. It flashes up ccm1 offline and then the cutterbar stops dead, you can't operate anything on the header up/down etc but the drum is still running normally. At the same time an error saying 'communication lost' and 'mdm offline' also appear. If I turn the ignition off and then start up again it runs fine until it happens again, sometimes an hours time and sometimes never again the same day. Any help would be much appreciated. Tia

Are these the same symptoms you had with that connector under the cab?

I had it on my last cx, took all the big connectors apart, some under the cab, some on the chassis, some up in the engine bay and the others under the side guards, canbus system I think?cleaned them up and it solved the problem

By cleaning them up you mean parted the plugs and sprayed with wd 40 or similar?

No header risers one side good place to start though

Electrical contact cleaner would be better I’d imagine, when I undid mine some of the pins had gone green

You will find that separating the connectors a few times with the contact cleaner (try WD40 first) will clean the contact for you. If you find discolored pins your sorted, clean until back to original.
