I am on my second (New) ETM same car
The very first download did stop. I restarted download "stated complete"
but car ran poor with code in cem (CEM-1A5D) I tried again with good download same code in CEM. This time tried upgrade software same code.
I tried both downloads. Replacing the Node,and Not replacing the node.I would assume replacing Node would be complete ETM software. and not replacing Node would be up grade?
I have replaced many ETM's I have never had a problem.
Is it true once ETM is pluged into car it belongs to that car only?
At this point I put old ETM back in car and installed (not replacing node) upgrade ETM software. There is no codes in CEM.
