Modify vin number of srs unit

[fuzz1]

Hi
What tools do you need to modify vin number in srs unit?

Would vcds do it for vag airbag ECU?


Thanks

VIN set's via EEPROM, it's simply)
But you need a right codding for you car if srs unit used from another car.

Depends on a car. Ford can be done by CPT for example.

I did for PSA cars via telecoding online though.

Hi
If i modify vin in eeprom what should be done to keep the integrity of the dump? Crc check will fail

[svenin53]

Need a CRC Calc)

[fuzz1]

Does UPA s have that possiblity to modify the crc? Saw that in the soft but i admit don't know how to use it

Tried it and successfully done it. Many a times. Believe me [emoji41][emoji41]

Hi

Would you mind sharing how you did it what tool you used and on what module?

thanks

Hi buddy
I have done this on modules with similar hardware but different memory files. The modules of hyundai, kia, suzuki, toyota etc are similar hardware wise but have different part numbers and versions and can be successfully swapped. Replace the d flash, p flash, d+p flash and boot files of the memory chip and the module can be used in other vehicle. I just did it 2 days back with modules of suzuki s cross 38910-64m10 and suzuki vitara brezza 38910-82p10.
Thanks n stay safe mate

Hi
Thanks just wondering how to change the vin number while keeping the file integrity. I know you can adapt it to some cars via obd port.
Would you mind giving an example of one where you change vin number in a dump and make it pass crc check.

Hi
I think i got wrong. The example which i gave have spc560p50lc memory chips in both. When repairing the crash, the d flash needs to be repaired for this. But when i put the d flash and the p flash files from the donor into the receiver, it has laa the data from the old part number and the old vin number. The redundant data is all gone and has new required data in it. I will pm you the old crash files and the new files for both
Thanks buddy
