Can the airbag module code be read before resetting it?

Yes, the airbag module codes can be read while the module is still in the vehicle before sending it in for repair. Using an OBD2 scanner, you can access the diagnostic trouble codes (DTCs) stored in the module.

However, if the module is removed from the vehicle, scanning for codes becomes difficult. Since it's no longer connected to the vehicle, it may display every possible code, making it unreliable. For an accurate reading, ensure the module is scanned while still installed in your vehicle before sending it in for resetting.
