CTB007 PRO OBD2 Breakout Box ECU Testing Tool Bench with LCD Digital Display CAN Test Automotive Diagnostic Tool Περιγραφή

Features: 1.12 V / 24 V Compatible Circuit Tester Robust design for passenger cars and commercial vehicles. 2 .Real- OBD-II Pin Voltage Monitor (VRMS / true RMS)
Power/ground integrity: e.g., pin 16 (+B) and pins 4/5 (grounds). Bus activity CAN / K-: checks whether static/dynamic levels reasonable; a green background indicates dynamic values. Pin assignment sanity-check: quickly validates expected wiring retrofits or suspect harnesses-replacing basic VPP voltage checks.
120 Ω CAN Termination Switches Inserts a 120 Ω resistor across the CAN pair to compensate for missing termination during single-ECU or small bench networks, improving signal integrity and reducing reflections.
Bench Testing Support Provides convenient connectivity for IGN/START activation or external wake- tools so ECUs can be powered and exercised the bench.
Important Notes For professional use. Incorrect pin bridging or inappropriate termination can damage ECUs or wiring. Pins 3/11 are OEM-defined; only use the MS-CAN terminator when the vehicle actually implements CAN these pins. The real- voltage view is a quick health check and does not replace an oscilloscope for waveform analysis.

Signal Status
Pin background flashing green = dynamic signal.
High/Low Voltage Audible Alarms
Low-voltage (slow beep):
12 V systems: < 11.8 V
24 V systems: < 23.6 V
High-voltage (fast beep):
12 V systems: > 15.5 V
24 V systems: > 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)
Allows a trained technician to momentarily bridge selected OBD pins via current-limited paths for OEM-approved procedures (e.g., make-specific communication or synchronization tasks).
