VDIAGTOOL V500 PRO MODE 1 ---- Smart Test & Multimeter Mode

1.Smart Test

Different from traditional power circuit testers, the 2025 VDIAGTOOL V500PRO 2 IN 1 Automotive Power Circuit Probe Breaker Finder can automatically identify the signals under test, such as voltage, current, resistance and other parameters in the circuit, and save switching time between different test modes , allowing customers to focus on repairing circuit faults.

2.Multimeter mode

Multimeter: The multimeter in the VDIAGTOOL V500PRO intelligent circuit probe detector is mainly used to measure basic parameters such as voltage, current, resistance, etc. in the circuit, and has a wide measurement range:

Voltage Test：0.1-100V;

Resistance Test: 0KR-200KR;

Current Test：2mA-25A;

Frequency Test: 10Hz-1MHZ;

Oscilloscope:10Hz-100KHZ.

VDIAGTOOL V500 PRO MODE 1 RELAY TEST

Quickly verify the operation of 4-terminal and 5-terminal relays to ensure proper electrical circuit functionality.

✔ Universal Testing : Works with both 4-terminal and 5-terminal relay types

✔ Real-time Voltage Display : Shows operating voltage (e.g., 12.2V for automotive systems)

✔ Quick Verification : Instantly confirms proper relay switching and coil operation

Common relay tests include:

1.Voltage test;
2.Coil resistance test;
3.Relay action test;
4.Relay delay and retention test.

VDIAGTOOL V500 PRO MODE 1 0-5V POWER SUPPLY

Supply provides a stable, adjustable, low-voltage power supply for customers' circuit diagnosis. It can simulate input voltage, test sensors, check circuit performance, and help with system calibration. Ideal for diagnosing low-power electronic devices, it helps users find faults quickly, avoid damage from mistakes, and make circuit debugging easier.

1.Sensors: oxygen sensors, temperature sensors, pressure sensors, etc.;

2.Motor drive modules: electric windows, electric seats, etc.;

3.On-board communication modules: CAN bus interface and other low-power communication modules;

4.Relays and switches: lights, fans and audio systems;

5.LED indicators: engine fault lights, oil pressure warning lights, etc.

VDIAGTOOL V500 PRO MODE 1 Component Activation & Injector Test:

1.Component Activation: Used to test and confirm the function of each circuit component by activating them, helping quickly identify faults, improve maintenance efficiency, and reduce unnecessary replacement costs.

2.Injector Test：Injector testing is often used to detect the performance and working status of automotive injectors. Through testing, the injection frequency, injection volume, and injection pattern of the injector can be evaluated to ensure that it can accurately supply fuel when the engine is running. There are 4 modes for injector testing:

👉 Mode 1: One 250 millisecond positive electrode
👉 Mode 2: Cycle positive for 7 milliseconds, negative for 20 milliseconds in 1.4 seconds
👉 Mode 3: Cycle the positive electrode for 4 milliseconds and the negative electrode for 10 milliseconds in 1.4 seconds
👉 Mode 4: Continuous output of positive pole for 7 milliseconds and negative pole for 20 milliseconds

3.Through injector testing, customers can bring the following conveniences:

👉Fault diagnosis: quickly identify injector problems, such as injector blockage, uneven injection amount, injector leakage, etc., to reduce troubleshooting time;
👉Performance optimization: ensure the normal operation of the injector, improve engine efficiency and power output;
👉Cost savings: avoid unnecessary injector replacement and reduce repair and maintenance costs.

VDIAGTOOL V500 PRO MODE 2 Breaker Finder

When VDIAGTOOL V500PRO 2 IN 1 Car Power Circuit Probe Kit Breaker Finder Tester switches to mode 2, it is equivalent to V210, with 3 test methods:

1. Checking Short Circuit – Identifies unintended connections causing excessive current flow, helping prevent damage to wiring and components.

2. Locating Open Circuit – Detects breaks or disconnections in circuits to restore proper electrical continuity.

3. Wire Tracing – Follows and maps wire paths, simplifying the identification of correct connections in complex harnesses.
