Lexus NX300h crash
Hi

I have Lexus NX300h airbag ecu to clear crash
89170-78040
cpu: h8sx/1797

I readed 512kb flash dump with iprog+ by can adapter
How to clear crash? erase flash, erase eeprom or modify original flash data and write back?

Flash write possible by can, or by uart?

If someone cleared this type of srs ecu, please share some info with me

thx
Tom
