A professional advanced breakout box for invehicle diagnostics / bench ECU testing, supporting both 12V / 24V systems.

More than just a basic breakout box - it exposes every OBD-II pin, monitors live voltages (true RMS), provides optional CAN termination, and supports safe, fast hookup of other diagnostic devices.

Key features:

• Universal compatibility: Works seamlessly with both 12V and 24V OBDII systems.
• VRMS Voltage Monitoring In Real Time: LCD displays true RMS voltage on all 16 OBDII pins. Visual feedback shows dynamic signals (green background), and immediately alerts for power / ground issues (pins 4 / 5 / 16)
• Built-In CAN Termination Switch: Applies a 120 resistance across the CAN pair to compensate for missing termination during single-ECU or small bench networks, improving signal integrity and reducing reflections.
• Voltage Protection & Alarm System: Features automatic audible alarms for high/low voltage deviations and reverse polarity protection. Supports a maximum load current of 2A.

Replacement battery cable clamp for the ET2709 code reader / battery tester.

An advanced CANbus circuit tester compatible with both 12V and 24V systems.

Provides a live display of present communicating signals, and can display the voltage of each pin without having to use a multimeter.

Essential for checking ground / voltage on all OBDII pins prior to connecting a scan tool / flashing ECU. If your scan tool cannot communicate, it could simply be a fault with the OBD connector.

• Connect inline with scan tools, Or use with a multimeter / oscilloscope.
• Quickly diagnose CAN faults.
• Monitor battery voltage at the OBD port.
• A great way to log pin voltage data when used with our ET2504 multimeter.

• 14 Pin Benz connector

• 20 Pin Isuzu connector

• 3 Pin Isuzu connector
