Main Features

Direct 16-Pin OBD2 Access – Provides convenient access to all 16 OBD2 DLC pins, allowing technicians to perform targeted circuit, power, ground and communication-line checks without repeatedly back-probing the vehicle connector.
Real-Time Voltage Display – Displays the voltage measured at the selected OBD2 interface point, helping technicians quickly observe circuit conditions during diagnostic procedures.
LED Connection & Activity Indicators – Integrated LEDs provide convenient visual cues for identified power, ground and communication lines, helping technicians locate relevant circuits before carrying out detailed measurements.
Scanner Pass-Through Connection – Allows a compatible diagnostic scanner to remain connected inline while individual OBD2 pins are accessed for simultaneous scan-tool and electrical testing.
Multimeter & Oscilloscope Compatibility – Provides accessible test points for compatible 4 mm leads, multimeters and oscilloscopes, supporting voltage, waveform and circuit-condition analysis.
Switchable 120 Ω Resistor Mode – Includes a 120 Ω series-resistor function for use with applicable vehicle network diagnostic procedures and specified circuit configurations.
Temporary ECU Power Support – Supports connection of a suitable external power source for temporary ECU power during approved service procedures, subject to correct voltage, polarity and vehicle-specific requirements.
Power & Ground Circuit Testing – Provides accessible breakout points for checking OBD2 connector power supplies and grounds using suitable diagnostic measuring equipment.
45 cm Flexible TPU Cable – Features a flexible and durable 45 cm TPU diagnostic cable that allows convenient positioning of the breakout box while working around the vehicle interior.
Professional Network Diagnosis Support – Assists technicians when investigating communication faults, network bias voltage, waveform behaviour, termination and other vehicle network conditions when used with the correct test equipment and vehicle-specific procedures.
Built-In Input Jack & Power Cable Support – Provides dedicated power hardware for applicable external supply procedures while keeping diagnostic connections organised and accessible.
Workshop-Safe Diagnostic Access – Moves pin-level testing away from the vehicle DLC to an accessible interface, helping reduce repeated probing of the vehicle connector during professional diagnostic work.
