AUTOOL Upgraded OBD2 Breakout Box for automotive diagnostics

AUTOOL OBD2 breakout box with 45 cm diagnostic cable

The AUTOOL Upgraded OBD2 Breakout Box provides technicians with direct access to all 16 OBD2 diagnostic connector pins for professional vehicle circuit and communication testing. Designed for use with compatible scan tools, multimeters and oscilloscopes, it features real-time selected-pin voltage display, LED connection-state indicators, 4 mm test access, a switchable 120 Ω resistor mode and a flexible 45 cm TPU cable for convenient workshop diagnostics.

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, providing technicians with a convenient reference during electrical circuit and diagnostic testing.
• LED Connection-State Indicators – Integrated LED indicators provide quick visual cues for identified power, ground and communication lines, helping technicians observe connection status or line activity during diagnosis.
• Scanner Pass-Through Connection – Allows a compatible diagnostic scanner to remain connected while individual DLC pins are accessed with suitable test leads, a multimeter or an oscilloscope.
• Multimeter & Oscilloscope Compatibility – Provides accessible breakout points for connecting professional test equipment when investigating voltage, ground integrity, network signals and vehicle communication behaviour.
• 4 mm Test Lead Access – Supports compatible 4 mm banana-plug test leads, providing convenient connection points for external electrical measurement and diagnostic equipment.
• 120 Ω Series Resistor Mode – Includes a switchable 120 Ω series resistor function for diagnostic procedures where the specified network topology, insertion point and vehicle testing method require it.
• External ECU Power Support – Provides an external power input for temporary ECU power support during approved service procedures, subject to correct circuit compatibility, polarity, voltage and load requirements.
• DC 6–30 V Operating Range – Supports a DC 6–30 V working range for appropriate automotive diagnostic applications within the breakout box's specified operating limits.
• 45 cm Flexible OBD2 Cable – Features a 45 cm TPU diagnostic extension cable that provides flexibility, durability and convenient positioning of the breakout box during workshop testing.
• Power & Ground Circuit Testing – Provides accessible test points for checking OBD2 connector power and ground circuits with an appropriate meter before interpreting communication or network conditions.
• Communication Signal Test Access – Enables technicians to access relevant diagnostic lines for waveform, voltage and communication checks using suitable test equipment and vehicle-specific procedures.
• Professional Network Diagnosis Support – Assists with investigating network resistance, bias voltage, waveform behaviour, termination and module communication when used with the correct vehicle wiring information and diagnostic procedure.
• Workshop-Friendly Diagnostic Interface – Moves individual OBD2 pin access to an accessible test interface, helping technicians perform organised measurements while keeping compatible diagnostic equipment connected.
