TachoSoft Airbag Resetter v6.4 is a reverse-engineering artifact from an era when airbag modules stored crash data in plaintext EEPROMs. It remains functional for that limited vintage, but modern vehicles use encrypted flash, rolling counters, and authenticated deployment logs.
If you must use v6.4:
Bottom line: A useful tool for its time, but obsolete for professional use on modern cars. Treat it as a learning tool or legacy solution, not a safety repair solution.
TachoSoft Airbag Resetter v6.4 is a specialized automotive software tool designed to repair and reset airbag control modules (ECUs) after a vehicle has been involved in a deployment event. When an airbag deploys, the ECU typically stores "crash data"—a permanent fault code that standard diagnostic scanners cannot erase. This software is used by technicians to clear that data, restoring the module to its original factory state without requiring a costly hardware replacement. Key Features and Capabilities
Crash Data Removal: The primary function is to erase stored crash history and internal "Controller Fault" codes that trigger the airbag warning light. The primary feature of TachoSoft Airbag Resetter v6
Database Support: Version 6.4 includes a vast library of "calculators" or data patterns for hundreds of airbag module brands, including Bosch, Siemens, TRW, and Continental.
Broad Compatibility: It covers various vehicle makes such as BMW, Mercedes-Benz, Audi, Toyota, and Ford.
File-Based Processing: The software typically works by reading the EEPROM or MCU chip dump from the airbag module (using a separate programmer), processing the file to "clean" it, and then writing the repaired file back to the module. Technical Workflow
Extraction: A technician removes the airbag ECU from the vehicle and uses a hardware programmer (like UPA-USB or Xprog) to read the internal memory.
Selection: The user opens TachoSoft v6.4, selects the specific vehicle make, model, and the part number of the airbag module.
Repair: The user loads the "dump" file into the software, which identifies the crash data strings and modifies them to match a "clean" state.
Reinstallation: The modified file is written back to the ECU, and the module is reinstalled in the car to clear the SRS (Supplemental Restraint System) warning light. Important Considerations
Safety and Liability: Airbag systems are critical safety components. Improperly resetting a module or failing to replace damaged sensors can lead to system failure during a future accident.
Hardware Requirement: TachoSoft is a software-only solution; it requires a separate hardware programmer to interface with the vehicle's electronic chips.
Legacy Status: While v6.4 is a widely circulated version in the aftermarket community, it is often found as part of older diagnostic suites.
The TachoSoft Airbag Resetter V6.4 strikes the ideal balance between professional capability and affordability. It empowers technicians to bypass expensive dealer-only repairs, reduce electronic waste, and turn salvaged modules into reliable, safe components. With support for thousands of modules, a straightforward reset wizard, and a vibrant community of users sharing pinout guides, V6.4 has earned its reputation as a go-to tool.
Whether you run a high-volume body shop or a mobile diagnostic business, investing in TachoSoft V6.4 – alongside a solid programmer like Carprog – will pay for itself after just a few successful resets. Always prioritize safety, follow proper chip handling procedures, and keep your software database updated. Resetting airbag modules has never been more accessible.

TachoSoft Airbag Resetter v6.4 is specialized desktop software used by automotive technicians to clear "crash data" stored within a vehicle's Airbag ECU (Electronic Control Unit) after an accident has occurred.
When a vehicle is involved in a crash that triggers the airbags or seatbelt pretensioners, the Supplemental Restraint System (SRS) computer logs an unerasable hard code known as crash data. This fault cannot be cleared using a standard OBD2 diagnostic scanner. TachoSoft Airbag Resetter v6.4 provides an automated, algorithm-based solution to overwrite those hard codes and restore the module to its factory-cleared state. ⚙️ Core Functions & How It Works
The software does not connect directly to the car via an OBD2 port; instead, it is an EEPROM/microcontroller dump editor. The typical repair procedure follows these distinct phases:

Based on user reports and internal file references (v6.4 circa 2010–2014):
| Manufacturer | Common Modules | MCU Type | Reset Method | |--------------|----------------|----------|----------------| | Bosch | VW Golf 4, Audi A3, BMW E46 | Motorola HC08 | Direct EEPROM (24Cxx) | | Siemens | Ford Focus, Mazda 3 | Infineon XC800 | Boot mode via K-Line | | TRW | Fiat, Chrysler, Jeep | ST72F | BDM or SPI | | Autoliv | Volvo, Ford | Renesas H8 | Direct to PCB | | Denso | Toyota, Honda | Custom µPD78F | Rare support (partial) | | Continental | Mercedes W204, BMW F10 | Infineon Tricore | Not supported in v6.4 |
Critical limitation: v6.4 does not support modules with encrypted or locked MCUs (e.g., Infineon XC23xx, Tricore, Renesas V850 with security bits). For those, you need TachoSoft v7+ or dedicated tools like CGDI, VVDI Prog, or SMOK.
Even experienced users encounter issues. Here’s how to solve frequent V6.4 problems:
| Error Message | Likely Cause | Solution | |---------------|--------------|----------| | No response from programmer | Wrong COM port or driver | Change COM port in Device Manager; reinstall drivers | | Chip not recognized | Incorrect chip selection | Manually check chip markings; use auto-detect if available | | Checksum error after write | Corrupt original dump | Restore backup and use “Fix Checksum” tool before writing | | Airbag light still on after reset | Module has physical damage or incomplete erase | Check crash sensors, seatbelt pretensioners; run secondary reset | | Software crashes on Windows 10 | Compatibility mode needed | Run as Windows 7, administrator, and disable Data Execution Prevention (DEP) for the .exe |
Always verify the chip orientation – Pin 1 is usually marked by a dot or notch. Reverse polarity can destroy the chip.
Use low-voltage adapters – Some modules (e.g., 93C56) require 3.3V logic, not 5V. Check datasheet.
Keep a logbook – Record vehicle model, module part number, chip type, and programmer settings for future reference.
Test before sealing – After writing, re-read the chip and compare the binary with the cleaned file. Then reconnect the module to the car but leave the case open until you confirm the airbag light extinguishes after ignition.
Don’t reset modules with physical damage – Melted capacitors, burnt traces, or water corrosion mean replacement is the only safe option.
