Based on the typical naming conventions for automotive electronics and Bluetooth modules, appears to be a Bluetooth Low Energy (BLE) or Classic Bluetooth module , likely intended for telematics, OBD-II diagnostics, or car infotainment systems .
(also known as Multidiag Pro+ or New VCI), a professional-grade vehicle diagnostic interface. This "Rev 1.0" board is typically a single-PCB (printed circuit board)
First, let's demystify the naming convention. The is not a full-fledged diagnostic tablet or laptop. Instead, it is a Vehicle Communication Interface (VCI) —specifically, a Bluetooth-enabled adapter that bridges your diagnostic software (running on a PC or laptop) to the vehicle’s electronic control units (ECUs).
Search for the Delphi unit (often named "Delphi DS150E" or "CDP"). When asked for a PIN code, enter (zero) or "0000" . Configuring COM Ports: Delphi 100 251 Rev 1.0 Bluetooth
In the electronics and diagnostic tool world, revisions matter. The hardware for the Delphi 100251 is highly regarded because it often features:
If you have ever peered into the world of automotive repair, you have likely encountered the Delphi 100 251 Rev 1.0 —more commonly recognized as the core of the Delphi DS150E Bluetooth
The Delphi 100 251 is a Vehicle Communication Interface (VCI) that connects to a car's OBD-II port Based on the typical naming conventions for automotive
The is a specific hardware revision number identifier (New VCI 100251) associated with the widely recognized Delphi DS150E (and Autocom CDP+) multimark OBD-II automotive diagnostic scanners . This specialized tool serves as an essential bridge between a vehicle's onboard Electronic Control Units (ECUs) and a technician's computer or mobile device. By offering wireless convenience through integrated Bluetooth communication, this hardware revision has earned an enduring reputation among automotive technicians, workshop owners, and DIY enthusiasts for reliable, comprehensive vehicle system analysis. What is the Delphi 100 251 Rev 1.0 Bluetooth?
If the Bluetooth connection is unstable or fails to connect:
When repairing legacy systems utilizing this component, technicians must decide between sourcing an identical OEM replacement part to maintain original factory configurations or upgrading the system with an aftermarket digital audio adapter that taps directly into the vehicle's fiber-optic or copper auxiliary input lines. To help you with your project, tell me: The is not a full-fledged diagnostic tablet or laptop
The VCI serves as an all-in-one scanning solution across thousands of vehicle models manufactured globally from 1996 through the early 2020s. When paired with software environments like Delphi Cars/Trucks or Autocom, it unlocks deeper modules beyond the engine control module:
Ensure the VCI is receiving proper power from the car's OBD port (12V-24V). Summary of Specifications Description Model Delphi 100251 Revision Connection Type USB 2.0 / Bluetooth Supported Software Delphi DS150E / AutoCom Pairing PIN "0" or "0000" Applications Diagnostic, Coding, Programming
This board is a "VCI" (Vehicle Communication Interface) component. "Rev 1.0" typically identifies an early or standard single- or double-board design.
