TachoSoft Airbag Resetter v6.4 is a specialized diagnostic software designed to clear "crash data" from a vehicle's Airbag Control Unit (ACU). When a car is in an accident, the ACU stores a permanent fault code—often called a "hard code"—that typically cannot be cleared by standard OBD2 scanners and renders the module unusable. This software allows technicians to "reset" the module to its factory state, potentially saving the cost of replacing the entire unit. Key Features and Capabilities
Extensive Compatibility: Version 6.4 supports over 450 airbag ECU models across multiple car brands, including BMW, Chevrolet, Citroën, Honda, Hyundai, and Mazda.
Automatic Crash Data Removal: The software automatically identifies and erases crash data markers within the ECU's "dump" file.
Broad OS Support: It is compatible with Windows versions from Windows 7 through Windows 11 (32/64 bits). How the Reset Process Works
The software is not a standalone hardware tool; it is part of a larger technical process that requires external equipment:
Extract the Data: You must physically remove the airbag module from the car and use an EPROM/MCU programmer to read the binary "dump" file from the chip (e.g., 95160 memory).
Clean the File: Open this dump file in TachoSoft v6.4, select the correct vehicle/module model, and click the "Clear Crash" button to generate a "clean" version of the file.
Reprogram the Module: Write the new, cleaned dump file back onto the memory chip using your programmer and reinstall the module in the vehicle. Critical Considerations
Safety & Legality: 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.
Hardware Required: You cannot use this software via a simple OBD2 cable alone; you need separate chip-reading hardware like a KESS/KTAG programmer.
Version 6.4 vs. Online Services: While v6.4 is a popular offline version, TachoSoft Online also exists, offering a web-based automated clearing service for a per-use fee.

TachoSoft Airbag Resetter V6.4 a specialized software tool designed for automotive technicians to repair Airbag Control Units (ACUs) after a vehicle has been in an accident
. When an airbag deploys, the ECU typically stores "crash data"—a permanent fault code that standard OBD2 scanners often cannot erase. Key Features of V6.4 Crash Data Removal:
The primary function is to "clean" or delete crash data from the ECU's internal memory (Eprom or MCU), allowing the module to be reused rather than replaced. Extensive Database: Version 6.4 supports approximately 450 different Airbag ECU models across a wide range of car manufacturers. Dump File Processing:
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
), load it into TachoSoft to fix it, and then write the cleaned file back to the chip. How It Is Used Extraction:
Remove the airbag module from the vehicle and use a hardware programmer to read the data from its internal EEPROM or processor. Modification:
Open the TachoSoft V6.4 software, select the specific vehicle and ECU model, and upload the "dirty" dump file. The software automatically identifies and removes the crash lines. Restoration:
Save the newly "cleaned" file and write it back to the ECU using your hardware programmer. Verification:
Once reinstalled, the airbag warning light should turn off, provided no other hardware faults (like a blown clock spring or missing airbag) exist. Important Considerations Hardware Required:
TachoSoft is purely software. To use it, you need a hardware device capable of reading and writing ECU chips, such as the Safety & Legal:
Resetting an airbag module after a crash is a sensitive task. Ensure the physical airbags and seatbelt pretensioners have been replaced, as "cleaning" the software alone will not make a vehicle safe if the hardware is spent. Availability: TachoSoft Airbag Resetter v6

TachoSoft Airbag Resetter V6.4 is a specialized software tool designed for automotive technicians and DIY enthusiasts to clear "crash data" from airbag ECU (Electronic Control Unit) dumps after a collision. Key Features of TachoSoft V6.4 Extensive Database : Supports over 450 airbag ECU models
across various vehicle manufacturers, including Toyota, Honda, Nissan, and Renault. High Compatibility
: Known for its ability to interface with specific microcontrollers, such as the
, commonly found in vehicles from the early 2000s to mid-2010s. User-Friendly Interface
: The software is relatively lightweight and straightforward, making it accessible for users who have basic knowledge of EEPROM reading/writing. Cost-Effective : Professional reset services typically range from $50 to $150
, while purchasing the software—often available for around $25 to $30 —allows for multiple resets. How to Use TachoSoft V6.4 The process generally involves three main stages: Read the Dump : Use an external programmer (like a USB EEPROM Programmer
) to read the original "crashed" data from the airbag module's memory chip (e.g., 95160 or 68HC11). Clear the Data
: Open the TachoSoft software, select your specific vehicle model and module part number, then upload the dump file. Click the "Clear Crash" button to generate a new, clean data file. Write the Dump
: Use your programmer to write the new, cleaned file back onto the ECU's memory chip and reinstall the module into the vehicle. Important Considerations Hardware Required
: This is software-only; you will need a separate hardware programmer to physically connect to the ECU's chips. Safety First Legitimate sources:
: Airbag systems are critical safety components. Standard OBD2 scanners usually
clear hard crash data. If you are unsure of the process, professional services like are recommended. Anti-Virus Warnings
: Since these tools often include "keygen" files, they may be flagged by antivirus software. It is often recommended to disable firewalls during installation. or a recommendation for a compatible EEPROM programmer
As Tachosoft v6.4 is an older, legacy release, it does not demand high-end hardware:
TachoSoft Airbag Resetter v6.4 is not a standalone piece of software. It is a specialized utility within the broader TachoSoft Professional Suite, aimed at one specific, high-stakes task: clearing crash data from airbag control modules (ACMs) and restoring them to a "virgin" or reusable state.
Unlike generic OBD2 scanners that only read/clear fault codes, v6.4 operates at the microcontroller (MCU) and EEPROM level. It directly reads, modifies, or rewrites the serial memory chip inside the airbag module—bypassing the module's standard diagnostic interface when necessary.
Key distinction: This is not for clearing diagnostic trouble codes (DTCs). It is for resetting the permanent non-volatile memory that records crash events, seatbelt pre-tensioner firing, and deployment status.
Tachosoft Airbag Resetter is a specialized software solution used to clear "crash data" from airbag modules. When a vehicle is involved in an accident, the airbag module "locks" itself to prevent accidental deployment and to alert the driver that the system needs servicing.
Tachosoft v6.4 allows users to read the data file from the airbag module’s memory chip (EEPROM), process it through the software to remove the crash signature, and write the "clean" file back to the module.
