In the fast-paced world of automotive diagnostics, few names carry as much weight as Delphi Technologies. Known for producing high-quality OEM and aftermarket components, Delphi’s line of diagnostic interfaces has become a staple in professional garages and home workshops alike. Among their most discussed—and sometimes misunderstood—products is the Delphi 100 251 Rev 1.0 Bluetooth interface.

While the default Autocom/DS150E software is functional, the Delphi 100 251 Rev 1.0 Bluetooth can be used with third-party software in a limited capacity. Applications like FORScan (for Ford/Mazda), BMW INPA, and VCDS-lite can recognize the hardware as a standard ELM327 interface if you switch the Delphi tool into “Pass-Through” mode. However, results vary wildly by firmware revision.
Solution: The Delphi 100 251 Rev 1.0 requires manual vehicle selection. The “Auto-detect” feature fails on many clones. Manually input the make, model, year, and engine code. Additionally, some modules require ignition on (position II) and the headlights off to reduce electrical noise.
