Puma 2009 2.4 injector codes 8 or 10 digits?

Click image to enlarge

Hi can anyone shed some light on light on a injector coding issue.
I have recently bought a diagnostic tool to enable me to code my injectors to my truck
The tool takes me through a fairly logical process to get to the point where I have to input a 10 digit code. The problem I have is on my injectors have multiple codes written on the top and etched around the side. None of these codes have an obvious 10 digit layout. They only have eight digits also with lettering that is not available in my diet machine options..
The injectors (Denso) are the original units that came with the truck, although probably not the original units from birth. I’m sure it’s something obvious. It’s just the first time I’ve tackled this job and need a bit of guidance. Looking forward to the advice. Please see pic of the codes. I have got off the injectors. And a picture of the l The codes that my Diagnostic tool reads from the ECU.
Many thanks in advance..

I reckon it should be a set of 4 (1 per injector) 16 digit hex code (as seen in your screenshot of the tool) - On mine, there was a sticker from factory with the codes (the sticker is now long gone though, but I kept a picture…):

As above. On the 2.4, each injector has a code, and it's a 16 digit hex code.
You can find the code for each injector on the top of the plastic electrical connector of the injector, written on 2 lines.
Example in pic below.

Many thanks for your replies. The handwritten codes in the picture are what is written on my injectors. as I have a 10 digit option on The diagnostic tool.any ideas on what I should install as an injector code from my list of handwritten codes?
I just remembered there is a barcode on the injectors as well. Maybe this will give him more codes to choose from the only problem is I need to take the injectors out again again to read the barcode as they are on the inaccessible side.. …

Your handwritten codes are not valid injector codes for the puma 2.4
As already stated, the only valid injector code format is a 16 digit hex code for the 2.4

Ok….so found the correct injector codes right, where you said they would be.
So compared the injector codes to what my diagnostics tool was saying and the codes are identical the only error message I get now is to do a injector learning program when I try to do this I get to the very last stage and the diagnostic tool states a error in communications Tried wiping all of the error codes again and starting the sequence but still get the same message just wondering whether my Icar3 diagnostics tool doesn’t support this operation but it seems a bit weird that as you would think this was a standard function for most diagnostictools?
Also, if I try to edit an injector code, I get to the very last stage and again get the loss of communication error.
Does anybody have an idea on what I might be doing wrong or what the problem might be? Looking forward to your comments.
