TachoSoft’s Crash Data Resetter — quick SRS EEPROM cleanup for VAG & Peugeot 
Lightweight Windows utility that helps workshops remove stored crash events from
airbag control unit (SRS) dumps after verified repair. Select the ECU family from the
menu (e.g., VAG patterns 1C0, 1J0, 6N0, 6Q0, 8A0… or Peugeot), load the dump,
apply the reset, and save a corrected file to write back with your programmer.
What it does
Typical use cases
How to use
System compatibility
Tested on Windows 10 LTSC (2019); also runs on Windows 7 / 8 / 10 / 11 (x86/x64).
Minimum PC requirements
Good practice
Legal & safety notice
SRS systems are safety-critical. Follow OEM procedures and regional regulations. In many
jurisdictions, certain SRS components must be replaced after deployment. This post is for

apply the reset, and save a corrected file to write back with your programmer.
What it does
- Supported menus: VAG families (1C0/1J0/6N0/6Q0/8A0 variants), Peugeot groups.
- Crash clear logic: removes deployment/crash flags in the EEPROM image.
- Non-destructive workflow: keeps calibration and coding bytes intact.
- Bench friendly: ideal alongside your SPI/I2C/parallel EEPROM programmer.
Typical use cases
- After-module refurbishment where OEM allows reset following component replacement
- Data repair when a known-good configuration is required
- Creating clean files for legacy SRS ECUs during restoration projects
How to use
- Read the SRS EEPROM and save multiple backups.
- Launch the tool → Select Type → choose the exact ECU pattern (e.g., VAG → 6Q0 xxx xxx).
- Open the dump, run the reset, review the report, and save the corrected file.
- Write the file back to the module and perform a full diagnostic scan; clear DTCs and verify.
System compatibility
Tested on Windows 10 LTSC (2019); also runs on Windows 7 / 8 / 10 / 11 (x86/x64).
Minimum PC requirements
- CPU: Dual-core 2.0 GHz+
- RAM: 2 GB (4 GB recommended)
- Disk: <100 MB free
- Extras: EEPROM programmer, stable bench power supply
Good practice
- Always keep an untouched backup of the original dump.
- Match ECU family exactly; an incorrect template may corrupt data.
- After writing, verify with a professional diagnostic tool and inspect the entire SRS system.
