Instead of connecting directly to the car's OBD port, this software typically works by editing "dumps." You must first read the binary (.bin) file from the ECU using a separate programmer (like

Here is a general tutorial for using the TachoSoft Airbag Resetter V6.4 based on common online resources:

The process of resetting an airbag module with Tachosoft usually involves a few technical steps:

: Never modify an EEPROM file without saving an unaltered copy of the original crash dump first. If the cleared file corrupts the module, the original file is required to restore the unit.

The programmer reads the chip's memory and saves it as a raw .bin file on a PC. Processing with Tachosoft: Open Tachosoft Airbag Resetter v6.4.

: Resetting an airbag module is a highly sensitive procedure. In many regions, specific regulations govern the reuse of crash-involved safety components. Professional-grade software like TachoSoft Resetter is intended for trained technicians who can verify the physical integrity of the airbag system.

– Click “Reset Crash Data” or “Clear Airbag Faults.” The software modifies only the crash flag and DTC sections, preserving VIN and calibration data.

Always create and store a backup of the original, unedited crash dump file before applying any modifications. If a calculation error occurs, having the original file ensures the module is not permanently bricked.

The Tachosoft ecosystem has evolved significantly since the release of version 6.4. The most notable difference is in the licensing and business model:

Tachosoft v6.4 supports various memory chips found in older and mid-generation vehicles. It is highly effective for modules utilizing chips like:

When an automotive accident occurs, the airbag control module (ACM) writes permanent "crash data" or "hard faults" to its internal EEPROM or MCU memory chip. Even after replacing the deployed airbags, seatbelt pretensioners, and sensors, the airbag warning light will remain illuminated on the dashboard. Standard Diagnostic Trouble Code (DTC) scanners cannot clear these hard codes. This article provides a comprehensive overview of TachoSoft Airbag Resetter v6.4, explaining how it functions, its vehicle compatibility, and how to safely utilize it within a professional automotive programming workflow. What is TachoSoft Airbag Resetter v6.4?

Many jurisdictions have strict regulations regarding the repair and reuse of safety-critical components. Ensure that resetting modules complies with your local automotive repair laws. Never attempt to clear a module that shows signs of physical damage, water intrusion, or scorched components on the circuit board.

The is an automated calculator software used by automotive technicians to clear crash data and reset Supplemental Restraint System (SRS) airbag modules . When a vehicle is involved in a collision, the airbag control unit (ACU) records hard fault codes—often referred to as "crash data"—which permanently lock the module. While traditional OBD2 scanners cannot clear these hard codes, TachoSoft V6.4 processes the EEPROM dump files from the module to restore it to its factory-fresh, reusable state.
