WOYO CTB007 Mobile OBD2 Diagnostic Test Box Core Professional Functions
✅ ECU Bench Testing Without Vehicle Installation
Test repaired ECU circuit boards on a bench before reinstalling them into the vehicle, with built-in 120Ω resistors (PIN 6&14, 3&11) for stable signal transmission. One-touch IGN/ACC activation simulates the vehicle's ignition environment, enabling accurate offline ECU function testing and avoiding rework caused by on-vehicle testing.
✅ Real-Time 16-PIN Voltage & Signal Monitoring
Displays the voltage and communication signals of all 16 OBD2 pins in real time for rapid fault identification of vehicle electronic circuits. Equipped with intelligent high/low voltage alarm for PIN 16: slow beeps for low voltage (12V<11.0V/24V<23.6V) and fast beeps for high voltage (12V>15.5V/24V>31V), effectively protecting diagnostic equipment and vehicle electronic components from voltage damage.
✅ Precise OBD2 Port Fault Detection
Quickly check the OBD2 DLC port for common faults such as pin short circuits and reverse polarity before connecting other diagnostic tools, avoiding misdiagnosis caused by port issues. Specially optimized for brand-specific pin testing: Porsche (3&7), Volkswagen (1&6), Mitsubishi (1&4) and Toyota (4&13), covering mainstream vehicle brands on the market.
✅ Vehicle Data Protection During Battery Replacement
Maintain continuous 12V/24V power supply to the vehicle when replacing the car battery, effectively preserving vehicle settings including driving computer data, seat memory, navigation information and electronic control unit parameters—no need to reconfigure after battery replacement.
✅ Flexible Expansion & Mobile Operation
Easily connect other diagnostic devices to any OBD2 pin via the included expansion board and breakout leads, meeting complex testing and modification needs. Supports installation of 3/6 pcs 18650 rechargeable batteries (batteries not included) for cordless mobile use, perfect for on-site rescue and outdoor testing; the device also features battery charging function for convenient daily use.
✅ 120Ω Termination Resistor with Independent Switch
Built-in 120Ω termination resistors for single ECU or small bench networks to compensate for missing termination, improving signal integrity and reducing signal reflection. Independent switch design allows easy on/off control—only use for bench testing to avoid over-termination during normal in-vehicle operation.
