Smart 451 TRW Airbag light on after retrofitting but no dtc stored

[ochsenhuber]

Hello folks, I am retrofitted a switch for deactivation of passenger airbag (new original parts), then changed the coding with DAS (DevMode) and cleared all dtc (all Systems)
-> no dtc stored anymore, but the airbag light in dashboard still on (ignition on -> light on, then short off, then on again).
First I reverse all (disconnect switch and passenger airbag light again, recode the airbag control unit back to old values, then clear all dtc), but light still on.
Then I change the airbag control unit with another one (changed VIN, recode, cleared all dtc), but still the airbag light on.
Last I changed the dashboard (adapt on the car, mileage/VIN changed, car starts all ok), but airbag light still on.+
Now I am lost, no more ideas what to do ....
The deactivation switch for the passenger airbag is working fine, light comes on if turned off and otherwise
In dashboard, i read data (DevMode, look attachment), and there ist 517 SRS_IL 1 (on), but why?
I will be very happy about every input I can get
dump from airbag and dash in attachment, car is Smart 451 ForTwo 2008 62kW gasoline

Sorry, don't work, still same behavior - no error stored, but light still on.

Any other suggestions?

Maybe the airbag module is unlocked. Try to lock it with Star.
