Serial decoding
Jul 13^th, 2018 at 2:27am

When doing serial decoding of can bus signals. Do the values that come up in the decoding as red indicate corrupt data? The reason that I am asking is that I was decoding the VCAN on a Cummins ECM on a problem truck and was getting all red values. I switched to a brand new truck and picked the signal of the same two wires on the connector and got all red values of the ECM on the new truck. Wondering what is going on and if I was doing something wrong. Any suggestions? Thanks in advance.
