Hey, did you ever get this issue figured out because my srt-6 is doing the exact same thing. I too replaced the cps because the guy at autozone scaned my car and said that's what it was but.I didn't think to get the actual code from him. I have a new battery, new cps, and I'm looking at the relay circuit board and it looks fine. I will post a video of the relay since my phone won't upload a pic.
