How it works
- Read the memory of your airbag module with a programmer and save the dump.
- Upload the file in your account and enter the part number.
- We remove the crash record and return the repaired file, usually within minutes. If it cannot be done, the tokens go back to your account.
- Write the file back to the module and clear the fault codes.
No programmer? You can also send us the module. More answers in the FAQ.
