No codes other than the usual suspects: satellite radio tuner not active, function restriction due to communications interruption, low key fob battery voltage. Otherwise I'm code free. Occasionally I'll have the oxygen sensor 2 "delayed response" that will trigger a CEL, but that's only because I'm running a downpipe without a tune. I wonder if DSR is only activated from the factory if your car has driver assists, such as lane keep/departure, radar cruise control, etc.Lol wtf. More confusion to add to the mix. When you run a scan of your car, do any codes pop up?

I honestly have no idea what it is. It appears to be a passive fault, so no CEL triggered, and it doesn't appear to affect the car in any way negatively. Research came up empty on this one so I just ignore it every time.My car doesn't have those features but still has DSR activated. Very weird. Side note - do you know what the function restriction due to communications interruption is? I have that also. Seems to be related to the telecommunications module?
