The VDIAGTOOL V200 Pro is your all-in-one solution for tackling any electrical issue in vehicles. Whether you're chasing shorts, diagnosing open circuits, or testing voltage, this tool has every function you need—without switching tools.
Switch to Mode II to locate circuit breaker points, trace cables, and detect open circuits or current leaks efficiently. The built-in tone change feature helps you pinpoint issues without damaging insulation—perfect for cars, trucks, RVs, boats, and tractors.
With Mode I, access AC/DC voltage, resistance, diode, and polarity tests instantly. Know if a wire is live and determine circuit side (positive/negative) within seconds. No external battery needed—power it via vehicle battery or cigarette lighter!
Send activation signals to lights, fans, injectors, relays, and motors directly from the V200 Pro to diagnose malfunctions quickly. Also ideal for testing sensor/signal circuits after retrieving DTCs from your ECU.
Safety first! The V200 Pro features auto shutdown and reset in case of overload, protecting both your vehicle and the tool. You can also use this feature to deliberately test short circuit conditions safely.
Use the external headphone port to hear tone changes clearly while tracing wires in loud shop environments. A smart solution for precision diagnosis in any setting.
Includes a 20ft main cord plus 20ft extension for full access around the vehicle. Combined with alligator clips and cigarette lighter adapter, you’ll never be limited by power source or cable length again.
