WOYO CTB007 TRUCK Professional OBD2 Tester
24V to 24V/12V-14.5V Regulated Output Voltage Converter
It exposes all OBD-II pins, monitors live voltage (True RMS), and enables safe, fast connection with other diagnostic/programming devices.
Key Features:
1. Expensive Diagnostic Tool Protection：
Compatible with diagnostic protocols 12V-compatible tools are safeguarded.
2. Step-Down Regulated Conversion：
Delivers 4A 50W power, adjusting output voltage to 12V–14.5V for diagnostic equipment protection.
3. Accurate Current Display：
Precisely shows load-side supply current.
4. HD LCD Screen：
Simultaneously displays multi-channel RMS voltage values, allowing real-time pin status checks and easy fault troubleshooting during diagnosis.
5. Dual Operation Modes：
Press the Up and Down buttons simultaneously to activate direct voltage mode (Input = Output); press any button to revert to regulated mode.
Operation Instructions：
1. Precise Regulated Voltage Control：Short press to adjust output voltage precisely (12V–14.5V).
2. Direct Mode Activation：Press & hold both buttons simultaneously for ≥2s to enable "Input Voltage = Output Voltage" direct mode.
3. Regulated Mode Resume：After releasing, press either button randomly to restore regulated output mode.
4.Real-time OBD-II Pin Voltage Monitor (VRMS / true RMS):
Power/ground integrity: e.g., pin 16 (+B) and pins 4/5 (grounds).
Bus activity on CAN / K-Line: checks whether static/dynamic levels look reasonable; a green background indicates dynamic values.
Pin assignment sanity-check: quickly validates expected wiring on retrofits or suspect harnesses—replacing basic VPP voltage checks.
5.Signal Status:
Pin background flashing green = dynamic signal.
6. PIN 16 High/Low Voltage Audible Alarms:
Low-voltage (slow beep):
24 V systems: < 23.6 V
High-voltage (fast beep):
24 V systems: > 31 V
7.Ground Status Indication:
Pins 4 or 5 show OPEN when no ground is detected,
and GND when a valid ground is present.
8. External power input:
24-31V DC, barrel 5.5 × 2.1 mm.
