if its the candoopro then the serial number on the back is the code and it would need to still have the maintenance active to be able to download the software.
Im not sure that model even works with the rfi.
On the only rfi I've used mine on (same as yours) it would not allow me to do anything
Id go candoo. So much better of a tool.
Im . A computer guy too and the programmer from that era is something i havent even started to look into. It works so haven't had to.
Try 6881.
Two of the ones i've used locally had that code. (they were bought from a closing dealership so maybe its only those two...)
The code is the dealer number which is why both of the programmers you ran across had the same number, That code will not work on his.
The programmer will work on models up to an RFI depending of course on what the last update installed on the programmer was.
