The “100 251 Rev 1.0” designation identifies the device’s hardware revision and serial number range. It acts as the bridge between the complex electronics of modern vehicles and user‑friendly diagnostic software. Equipped with both USB and Bluetooth connectivity, it allows technicians to read and clear fault codes, view live engine data, perform actuator tests, and reprogram electronic control units without being tethered to the car.
The 100251 serial identifier is widely supported across several generations of diagnostic software. The tool utilizes a cracked firmware activation ecosystem that matches specific software editions:
The Rev 1.0 designation indicates this is a particular hardware revision, and the 100251 serial number became a standard identifier for a specific type of VCI. This model gained popularity due to its ability to work with modern versions of the Delphi and Autocom diagnostic software.
Some versions of the hardware include a microSD slot for recording live parameters while driving without a connected laptop. Hardware Variations & Identification Delphi 100 251 Rev 1.0 Bluetooth
When connecting via Bluetooth, the default pairing PIN is typically 0000 or 1234 .

The Delphi 100 251 Rev 1.0 is not merely a "check engine light" reader. It is a full-featured VCI suitable for advanced tasks, including:
The phrase Delphi 100 251 Rev 1.0 refers directly to the internal printed circuit board (PCB) identifier and hardware serial baseline ( New VCI 100251 ) utilized by universal diagnostic adapters. When paired with standard diagnostic software suites (such as Delphi Cars/Trucks or Wurth WOW!), this specific tool enables cross-platform diagnostics across more than 48 major vehicle brands manufactured from 1996 through to recent model iterations.
The device connects directly to a vehicle's to read real-time data and perform system-wide diagnostics.
