Safety & legal notes

The application operates completely independent of an active internet connection, allowing technicians to perform calculations in remote workshops or mobile repair vans.

Using TachoSoft v6.4 is not a plug-and-play OBD2 diagnostic process. It requires a bench-top electronics setup. Step 1: Module Extraction

I had a with a deployed passenger airbag (used module). Bought a generic USB OBD cable (FTDI chip), downloaded v6.4 from a reliable source, and followed the guide.

The technician locates and removes the physical airbag control module from the vehicle (typically found under the center console or dashboard near the vehicle's center of gravity). The exact part number, manufacturer (e.g., Bosch, Continental, Denso, Temic), and the internal memory chip type (e.g., 95160, 95320, 24C04, CR16) must be noted from the module label. 2. Reading the Memory Chip (EEPROM/MCU)

Introduction Tachosoft Airbag Resetter v6.4 is a Windows-based utility used by automotive technicians and DIYers to read, clear, and program airbag (SRS) fault codes and to reset airbag control modules after repairs. Below is a concise, practical blog-style post covering features, compatibility, installation notes, usage steps, pros/cons, and safety/legal considerations.

Locate the airbag control unit inside the vehicle, typically found under the center console or beneath the dashboard. Disconnect the vehicle battery, wait 15 minutes for the capacitors to discharge, and remove the module. Open the casing to locate the EEPROM or MCU chip (e.g., 95040, 95160, 95320, or Motorola HC11). Step 2: Reading the Chip Memory

Airbag deployment systems are critical for vehicle safety. When a vehicle gets into an accident, the Airbag Control Module (ACM)—also known as the Sensing Diagnostic Module (SDM) or Restraints Control Module (RCM)—records "crash data" or "hard codes." Once these codes are written to the module's internal memory (usually an EEPROM chip), the vehicle's airbag light stays illuminated permanently. Even after replacing the deployed airbags, the module itself remains locked and unusable.

Why choose TachoSoft V6.4 instead of SkyTag, Carsoft, or Launch X431?

In the event of an accident, the airbag control unit deploys the safety features (airbags, seatbelt pretensioners) and locks itself with "crash data" to prevent reuse. While the physical components must be replaced, the control unit often remains functional but locked. Tachosoft provides a software solution to clear this data, negating the need to purchase an expensive new control unit.

Whether you are dealing with a or an internal module error ?

: 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).

– Launch TachoSoft V6.4, select the vehicle make, model, and module part number. Click “Read” to extract the binary file.
