@radoslaw317, the UPA-USB programmer goes by microcontroller models (i.e. MC9S12XDT384.) Instead of the SRS module part number, can you provide the microcontroller model inside the module for me to look up?
Thanks.

@radoslaw317, my UPA-USB programmer software is a bit old. Your particular NEC microcontroller is not on the list of supported NEC microcontrollers.
But I suggest you to install the latest free UPA demo version from Elrasoft (https://www.elrasoft.com/download.htm) and see if your microcontroller is supported.
Download the 2 items below:
Free Universal Programmer Analyser - UPA v2.3 Lite 485 KB
Free UPA v2.3 Lite PASSWORD RegistrationBy the way, I spent quite a few hours without getting good solder connections to the SRS PCB board. In the last 3 months, I succeeded 3 times (read and write) out of 100 attempts with a number of modules.
I will probably contact a professional to write the EEPROM binary file for me instead.
If there are other ways of programming the SRS module (without soldering) such as via the module connector or OBDII port, I would love to hear about them.
Thanks.

Thank you for Download links.
I mainly specialise with engine ECUs cloning and repairs I have a bit clue how to solder, and I have a professional tool to do it but I don't have many experiences with Airbags
my Programmer SVOD4 doesn't like Airbags but its excellent with ECUs.
For Airbag crash date I am using CG100X but there is no cloning option
if you struggle with soldering I more than happy to help I was ordered genuine UPA Programmer from their website with newest script catalogue, so I hope I going to sort this SRS and make some money on this vehicle -

Happy to share what I learned over the last few months from mechanics and forums on the Volvo SRS.Quite a few 2006-2011 S80, V70 and XCs use the same SRS module with part number 31264861.
A gentleman stated this particular module is not VIN-specific in one of the forums.
I believe this is correct as there is no VIN (in plain text) in my EEPROM dump. However, the module serial number and the TEMIC barcode code (only the first 10 characters) printed on the module label are present.
This leads me to believe that the replacement unit's serial no. and TEMIC barcode should be preserved during EEPROM cloning.Regarding the microcontroller flash, inspection of the 256K flash dump (which contains the software program) reveals the presence of the module serial number, Hardware num, Diag. num, Software num. 1 and Software num. 6 reported by VDASH. However, Software num. 2 is not present in either the EEPROM or the flash.
Important: I learned in another forum that changing the flash content will cause the SRS module NOT to communicate with rest of the system and there are confirmed cases.
The 2012-2016 S80 uses an entirely different SRS module which is VIN specific. See this video for EEPROM editing details: https://www.youtube.com/watch?v=HhEAUVbzBIo
Someone successfully replaced the S60 SRS module, seatbelts and cleared all fault codes after a minor crash: https://www.youtube.com/watch?v=n_PM_DRKoQkRegarding programmers for the microcontroller (part number 31264861,) I have seen Xprog being used. See one of the images in: https://diagmotors.ru/work-volvo-s80-31264861-srs-repair.php
Thank you for your offer to help. How can I contact you directly? I can do email and Whatsapp.
Many thanks!
