Error codes

Can any one help me with these... How can airbag error code be current when its not deployed as I am sitting in the car, I mean if it were deployed before I bought the car then shouldn't it be in in the history section...? The last picture with the ABS code sometime appear and sometimes disappears

according to the Service manual
'If DTC B1021, B1024, B1025, B1026, B1028, B1029 or DTC B1222 is stored in SDM, it is not possible to clear DTC.'
unfortunately, you have to replace SDM.

Airbag controller module

Did you try applying battery charger then go back into codes with the scan tool, erase codes and see if any or all codes will erase? I do know that after these set off bag,s and belt, s the module wont allow those codes to erase. The blown bag, s and belt, s along with the module must be replaced. Low voltage could be messing with you though.
