Reconnect the car battery, turn on the ignition, and verify that the SRS light illuminates briefly for a self-check and then turns off permanently. System Requirements and Installation Tips
The primary feature of is its ability to clear "crash data" from a vehicle's Airbag Control Unit (ECU) dump files , effectively resetting the module to its factory state after a collision. Key features and specifications of this version include:
Requires an external EPROM or MCU programmer to read the physical chip (e.g., 95160, 68HC912D60) from the airbag module User Interface: tachosoft airbag resetter v6.4
The process of using TachoSoft V6.4 generally follows these steps: Extraction:
Tachosoft Airbag Resetter V6.4 is a legacy tool that offers a low-cost, software-only method for clearing crash data. However, its manual and technically demanding process, combined with its age, makes it largely obsolete for professional use. Reconnect the car battery, turn on the ignition,
: If the light remains illuminated after a reset, use a diagnostic scanner to read the fault codes. The dump may be clean, but a hard fault could exist due to a faulty clock spring, unreplaced seatbelt pretensioners, or a loose wiring harness connector.

is a PC-based software application designed to read, erase, and reprogram crash data stored in the EEPROM and microcontroller (MCU) of airbag modules. Unlike generic OBD2 scanners that only clear diagnostic trouble codes (DTCs), TachoSoft V6.4 works at the chip level. It connects directly to the module via an external programmer (such as Carprog, UPA-USB, XPROG, or similar) and performs a binary reset of the crash event.
An activated airbag warning light is one of the most stressful indicators on a vehicle dashboard. It signals that the supplemental restraint system (SRS) is disabled, leaving passengers unprotected. While physical damage requires parts replacement, many warning lights are caused by minor electronic glitches or stored crash data after a minor bump.
: The software covers between 450 and 775 different airbag ECU models depending on the specific database version.
