98221CC0902 B1000 after clear

[bingo]

Hello. I have this ecu to be repaired. I have read secured MCU succesfully, and the generated cleared dump written, but after write, it has B1000 ECU fault stored too, and can't clear any DTCs on bench, neither installed back to the car, after replaced all damaged airbags.
Is there any similar experience? Is problem about the solution I think.
Any solution?

Select part number 98221AN000 and try Clear Crash by OBD.

no success, all operations fail

You can install an SRS unit on the car, where this error can be removed.

ECU returned from the car, it was unable to clear DTCs All operation refused by the controller on bench too

What error codes were there in the car? Full list with statuses.
You can try to write the cleared file and install the SRS unit on the car without diagnostics on the bench.

It has all dtc stored in the car, but cant clear any of them.
So you say write cleared file again, and do not power on bench???

I dont think ecu fault stored because of powered on bench

Your diagnostics cannot detect active errors.
Just do as I said and fix all errors.
