Those codes have been seen before in that combination and they ended up being caused by a improper /faulty battery current sensor. Some of them have burnt a hole in themselves. there is a TSB somewhere, it details that the wrong P/N current sensor was installed on some cars.

Purple haze that is the circular sensor on the cable. I have had both of mine replaced. First was the ecm, covered under warranty. The bcm wasn't and ran bout 6/700 installed by the dealer. No check engine lights have ever came on in my car when ever something was wrong with it.
