Airbag reset (also called SRS reset or crash data reset) is a procedure used to clear airbag warning lights and faults stored in the airbag control module.
In many vehicles, airbag faults cannot be cleared using a standard “Clear DTC” function. This is because the module stores permanent faults or crash data that require a special reset procedure.
This is where OBD2 scanners with airbag repair functions become essential.
When you need an airbag reset
You may need to perform an airbag reset if:
- airbag light is ON and cannot be cleared
- fault shows as static / permanent
- error like “control module faulty” appears
- vehicle was in a minor accident
- airbag module stored crash data
- battery disconnection caused SRS fault
What airbag reset actually does
Airbag reset function:
- clears crash data stored in the module
- resets internal fault memory
- restores module to normal operation
- turns OFF airbag warning light
In some cases, this procedure can save you from replacing the airbag control module.
How to reset airbag light using OBD2 scanner
Typical process:
- connect diagnostic tool
- open airbag / SRS system
- access special function (airbag reset / repair)
- select correct vehicle profile
- run reset procedure
- verify that warning light is gone
Some tools use predefined profiles (for example VW1, VW5, etc.), and the correct option may require trial and error.

When OBD airbag reset does not work
In some cases, the airbag module cannot be reset using OBD tools.
This usually means:
- internal memory is corrupted
- crash data cannot be cleared via software
- module is locked
In these situations, advanced repair is required:
- EEPROM reset (reading and rewriting memory chip)
- or replacing the airbag module
These procedures require specialized tools and soldering skills.
Important notes
- compatibility depends on vehicle and airbag module type
- not all scanners support airbag reset
- always ensure stable battery voltage
- incorrect use may cause additional faults
Legal & safety notice
This procedure modifies vehicle system settings through the control module. Incorrect use may cause faults or warning lights. Always ensure the vehicle is secured and follow proper safety procedures.
