AUTOOL OBD2 Premium Version

Product Overview

The AUTOOL OBD2 Breakout Box Protocol Detector Premium Version is a pass-through OBD-II diagnostic connector detector designed for vehicle diagnostics, OBD-II communication checks, power and ground line monitoring, and ECU data protection. It helps verify stable connectivity between diagnostic scanners and vehicle OBD-II systems, quickly identify communication or power supply issues, and provide convenient access to all 16 OBD2 pins for multimeter or oscilloscope testing.

The Premium Version supports an external 8-26V wide-voltage power supply to provide stable power support during diagnostics, helping reduce ECU data loss risk caused by unstable power. It also includes a 120Ω series mode so ECU data can still be read through the cable even when the ECU is removed, expanding diagnostic and repair possibilities beyond traditional OBD-II connection checks.
