CTB007 Pro OBD2 Breakout Box with LCD Display, 16 Pins, 120 Ohm Resistor

The CTB007 Pro OBD2 Breakout Box with LCD Display is a professional 12 V/24 V circuit-testing and signal-access tool designed for diagnostics, development, and bench testing. Built to expose every OBD-II pin, it helps you verify wiring, monitor live voltages, and safely hook up other diagnostic or programming devices. With the integrated LCD display, you get real-time readings right at your fingertips, so you can spot power, ground, or CAN bus issues as they happen.

Key benefits include robust CAN testing with optional termination, quick validation of pin wiring during retrofits, and a reliable bench-testing workflow that keeps ECUs powered and accessible. The device is suitable for both passenger cars and commercial vehicles, making it a versatile companion in any shop or lab.

Note: If you select the model “59inch No Cable” or “27inch No Cable,” you will only receive the CTB007 PRO package. If you choose “59inch and Cable” or “27inch and Cable,” you will receive CTB007 PRO plus CTBC001 ECU breakout leads. Before payment, please confirm which model you need. For more detail about the ECU breakout leads, please refer to the product pictures.

Benefits & Tips

• Use the Real-time OBD-II Pin Voltage Monitor (VRMS / true RMS) to verify power/ground integrity (e.g., pin 16 +B and pins 4/5 grounds) and to check CAN/K-Line bus activity for dynamic signaling.
• Enable the 120 Ω CAN Termination Switches when wiring a bench network or testing a single ECU to improve signal integrity and reduce reflections. Remember to keep termination OFF during normal vehicle use to avoid over-termination.
• Leverage the Battery Replacement Memory Saver to keep vehicle settings intact during battery changes, and use the Quick Jumper Function with a trained technician for OEM procedures that require brief pin bridging.

Product specifications

• 12 V / 24 V Compatible Circuit Tester for both passenger cars and commercial vehicles.
• Real-time OBD-II Pin Voltage Monitor (VRMS / true RMS) to assess power and signal stability.
• 120 Ω CAN Termination Switches to compensate for missing termination in bench networks (use for bench/missing-terminator scenarios; disable for normal vehicle operation).
• Bench Testing Support with convenient connectivity for IGN/START activation or external wake-up tools.
• Signal Status: Pin background flashing green indicates dynamic signal activity.
• Audible Alarms for Low/High Voltage to alert you to power anomalies (12 V: < 11.8 V / > 15.5 V; 24 V: < 23.6 V / > 31 V).
• Ground Status Indication: Pins 4 or 5 show OPEN when no ground is detected, and GND when a valid ground is present.
• Quick Jumper Function (technician use only) for momentary, current-limited bridging of selected OBD pins for OEM procedures.
• Battery Replacement Memory Saver to maintain vehicle power during battery changes.
• Connectivity: 70 cm extension lead for rapid hookup to other diagnostic/programming tools.
• External power input: 9–32 V DC, barrel 5.5 × 2.1 mm. Set to 12 V or 24 V to match the tested vehicle or module.
• Important safety note: For professional use. Incorrect pin bridging or inappropriate termination can damage ECUs.

Package includes:

• CTB007 PRO OBD-II Breakout Box (CAN Tester Box)
• CTBC001 ECU breakout leads (included when selecting cable-equipped variants as CTB007 PRO + CTBC001)
• 70 cm extension lead for rapid connectivity with other diagnostic tools
