Curious problem

[fokker2003]

Hi guys:

Have a curious problem with airbag unit in Renault Kangoo.
Vehicle was crashed. Pretensor and airbag were changed.
Trying to reset airbag unit with reference Autoliv 605044900 and Renault 8200381654 AB. All files we try with clear file, the unit don?t answer to diagnosis, seems like is not mounted in vehicle. Re-write with crash file and all is ok (except crash stored).
Tried Airbag 1.0, Airbag 6.4, Digimaster, Ico?s airbag reset, and 2 clear files we have stored, all with the same results, no communication with unit after writing new file.
Does anyone have a good dump for this unit please?

Attached ori crash file and some clear we have tried.

Bad clearing, to much bytes erased....

[fokker2003]

Yes, I think the same, but don?t know how to clear crash manually.
It?s strange that clear files doesn?t work too.

Sorry for late to answer, not necessary clear dtc faults. Only connect the unit and all ok.
