Hi Jason,
As you know the status shows an OCD fault which would turn off the DSG and a COV fault which would turn off CHG. If you run a log you can see when the fault occurs. Likely OCD is the parameter setting, likely COV is a unconnected wire. See the technical reference manual for parameter definitions.
If you need additional assistance after studying the results, post the gg file and log, possibly the schematic segment if needed.
