The VDIAGTOOL V200 PRO is a multifunction automotive electrical diagnostic kit designed for fast testing, troubleshooting and tracing of vehicle electrical systems
It combines a power circuit probe tester and a wire/open-circuit finder in one kit, helping reduce diagnostic time when working on automotive wiring, electrical components and circuits
In Mode I, the circuit probe provides four diagnostic modes: DC voltage, AC voltage, resistance and diode testing
It can check circuit polarity and continuity, identify poor ground connections, measure electrical values and apply positive or negative battery power directly to components for functional testing
The tool can directly activate and test electrical components such as lights, motors, relays, windshield wipers, radiator fans and fuel injectors, helping determine whether the component itself or its wiring is faulty
It also supports sensor and signal circuit testing
In Mode II, the breaker finder helps trace wiring and locate open circuits, broken wires, poor connections and current leaks without having to dismantle the wiring harness
Adjustable sensitivity and a flexible probe help locate faults in confined areas
The integrated short-circuit and overload protection automatically interrupts power output if an overload is detected, protecting both the tester and vehicle electrical system
After the overload condition is removed, the circuit breaker automatically resets
The long test cable provides convenient access around the entire vehicle
The circuit probe can be powered directly from the vehicle battery or through the cigarette lighter adapter
