I have these four codes. They seem to have one thing in common from my research on here. They all four "connect" to the PCM through circuit D511.

It seems that pretty often the culprit is a corroded plug in the wire harness near the driver's side fender.
My question is can anyone give me a better description of where this plug would be? I looked under the hood, there's some firewall wires but I'm at a loss where to look. Under the car? Remove wheel and inner fender well? Any help would be greatly appreciated. Trying to get rid of these codes so we can find this car a new home. What a great car except for these codes.

Hey did you ever find out what this was?

No, I sold the car as is with the codes

Maybe I bought it lmao

LOL! I don't think so. I gave the new owner everything I knew about it. Which is everything printed above. I pulled a few plugs, everything looked clean and nice so I gave up. I never took it to the dealer cause I hate dealers. The car ran perfect even with these codes. Good luck to you.

I will ask the new owner to let me know what it was when he gets it fixed. I will post it right here when I find out.

My WAG is the codes were from a low battery that caused a low power glitch upon engine start. My Hellcat proved to be prone to this from lack of regular use. Never got those codes though but the uConnect radio was affected -- Performance Pages refused to load -- and at least once the LCD came up the vertical blue bars showing.

A more serious problem was the +paddle would cause a down shift rather than an up shift.

Turning off the engine and restarting didn't help.

The shop foreman when looking into this found several low voltage errors logged (proprietary errors). He also found the car due for 3 updates, one for the PCM, one for the TCM, and one for the CAN BUS/Cruise control problem. These were applied.

But I also made an effort to drive the car more often. This eliminated the uConnect problems. It may have helped with the +paddle issue as well, but I never bothered to test this by leaving the car parked that long unused.

More recently I thought my 2020 Scat Pack was immune to this low voltage thing but it started manifesting signs of uConnect issues as I was letting it go too long between use. The signs/symptoms were very different load times for Performance Pages. Then when Performance Pages did load it would display stale data for some of the telemetry like oil temperature and coolant temperature.

The car was equipped with a manual transmission so the +paddle issue was not possible.

With both cars the engine never manifested any signs of any issues. No failure to start -- just a slightly slower crank speed that was not very noticeable -- no misfires no untoward engine behavior at all.
