I’m unable to provide a direct download, crack, or pirated copy of or any similar software. This program is typically used to reset airbag crash data in automotive electronic control units (ECUs), and unlicensed versions often circulate with malware risks or legal issues.
For years, automotive technicians and DIY enthusiasts have turned to software solutions like to clear these faults. This comprehensive guide explores what this software does, how it functions, the safety risks involved, and modern alternatives. What is TachoSoft Airbag Resetter v6.4?
Tachosoft Airbag Resetter v6.4 is a specialized database and calculation software used to reset, clear, or repair airbag modules. Unlike generic OBD2 scanners that only clear active fault codes, Tachosoft works by editing the EPROM or MCU dump files within the airbag module. Key Features of v6.4:
Instead of manually searching through thousands of lines of hexadecimal code to find the crash bytes, the software automates the process. It identifies the exact offsets where crash logs are stored and overwrites them with clean initialization values. Cost Efficiency
: Some advanced modules run an internal verification string called a checksum. If TachoSoft clears the crash data but fails to correct the checksum bytes, the module will lock itself and flag an internal control module memory error (DTC B1000 or equivalent). Vital Safety and Legal Considerations
: Save the newly cleaned dump and use your programmer to write it back onto the EPROM chip.
| Mode | Method | Typical Use Case | |------|--------|------------------| | | Via vehicle diagnostic connector | Modules that allow reset commands in boot mode (rare) | | Direct-to-PCB | Soldering leads to EEPROM pins (SOIC-8, SOP) | Most modern modules | | Clip/Probe | Using a SOIC-8 clip without desoldering | Quick access, but unreliable on conformal coating | | JTAG/BDM | For Motorola HC(S)12, HC08 families | Older Ford, GM, European modules |
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.
The module is reinstalled, and the airbag light should turn off. Supported Vehicles and Modules
TachoSoft Airbag Resetter v6.4 is a Windows-based database and calculator software used by automotive technicians. It provides instructions and data patterns required to clear crash files from the EEPROM (Electrically Erasable Programmable Read-Only Memory) chip inside a vehicle's SRS module.
TachoSoft Airbag Resetter v6.4 is one of the largest digital databases for airbag module EEPROM (Electrically Erasable Programmable Read-Only Memory) file modification. It acts as an automated "clearer" for corrupted dump files. Key Specifications Automotive SRS Repair / EEPROM Calculator Version: 6.4 (Final stable iteration of the legacy tool) File Compatibility: .bin , .hex , and .eepr dump files
While clearing crash data is a common practice in automotive remanufacturing, using software like TachoSoft carries significant responsibilities.
The software will instantly process the file, wipe the fault codes, and prompt you to save the new file. Save it as clear_dump.bin . Step 4: Flashing and Reinstallation
Instead of plugging directly into a car's OBD2 port, this software works with . A technician uses a physical chip programmer to read the hex data from the airbag module's memory chip, opens that file in TachoSoft, and lets the software automatically locate and erase the crash logs. Key Features of Version 6.4
Open your programmer's software, select the correct chip ID, read the memory, and save the raw file immediately as original_crash_dump.bin . Step 3: Clearing the Crash Data with TachoSoft v6.4 Launch the TachoSoft Airbag Resetter v6.4 application.
Modern diagnostic scanners like those from , Launch (X431) , or Snap-on can clear advanced SRS codes directly through the OBD2 port on many newer cars, eliminating the need to desolder chips. Dedicated EEPROM Software
