You pressed the "erase" button?

Or when recording, the flash was deleted and the recording did not start?

 

Use the correct punctuation marks to correctly understand the meaning of the sentence.

В этих блоках нет ошибки по крашу, как ведёт себя лампа Airbag на панели приборов и какие ошибки присутствуют?

thanks for reply.

 the original file was lost. (my mistake, no backup) , on first time i wrote empty file via UART  but there was no communication with the module,

so i wrote a recupery dump from other number of module with result i got communication but didn't turn off the light on cluster and there are fault codes on it 

B1633, B1638, B1651, B1660, B1806, B1821.

So no original file ... thanks in advance for any help
