The reason is shown as follows.

The support range for AITO’s airbag ECUs extends up to the year 2023, with airbags from before

December 2020 is repairable through the BENCH mode. Practical tests reveal two repair cases for 2021-2022 airbags under the same part number: one involves merely unlocking the chip, while the other necessitates unlocking followed by additional data processing.

In this case, we need to use the “Advanced function” to read and write all data.

First, read all data (BENCH)
