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.
