I have had a problem with a low batery voltage and am left with a DTC B1009 which I can clear but which recurs when I restart the ignition. I also show the message above"RIM PROM ID 8410".Does PROM mean powertrain control module reprogramming?What does ID 8410 mean? All this comes up on the DIC. Any help gratefully received

You are getting an internal memory checksum error, basically a computer is telling you it is bad.
It looks like two modules can report this condition.
Does this message just come up or are you seeing it on a code check?

The RIM or the VTD module can set this code.
(Rear Integration Module or Vehicle Theft Deterrent)
Other modules might set this code also. Do you know how to activate the on board diagnostics? You need to see which module this code is coming from so you can know which one to replace. It is bad whichever it is.

PROM = Programmable Read Only Memory
It is an old computer chip term.
