Got down to investigating a current draw on the car (Chevrolet Corvette C6 2005 – 2013 ) and narrowed it down to the OBD circuit and radio circuit. I have a PAC RP4-GM11 harness that seems to be zapping away 45ma ,and a draw coming from the OBD port which has a dashlogic connected. For now the dashlogic is disconnected. I ordered a new pac harness that I’ll be swapping out.
I plugged it in today and reset it, worked like a charm. I’m not going to worry about that until I figure out the current draw I have on my radio circuit. I think it might be the PAC module but I can’t tell for certain. I replaced the module and the harness today and the 45ma current draw on the radio circuit persists. There is currently no radio in the car, and the harness is not powering anything other than the module. I also removed the xm module that I discovered is powered on the radio circuit, and I unplugged the rdclr module — no change.
I ordered a vxdiag vcx nano gm obd2 scanner to see if any of the modules aren’t going to sleep. Not sure I have any ideas outside of that.
Trying to understand the rdo/s-band/vics circuit. From what I can gather, it powers two things — the head unit and the xm module. Just need to rule out the possibility of something else on this circuit drawing power. In the car right now the head unit and xm module are both removed from the vehicle. Adding the RP4 GM11, the circuit shoots up to 45ma. On the phone they stated 10ma is what it should draw.

Everything was looking OK on the tech 2. I tried two RP4 GM11s that both had the same issue so this time I tried an RP5 GM11 and I tested the circuit after radio shutdown — power on that circuit gradually falls all the way to zero within 15 seconds of radio shutdown. I think that should fix it. Just wondering now if the DTCs set by the driver door module are anything to care about.
