How to Activate Components with V200 Pro
When troubleshooting vehicle electrical problems, one of the most effective ways to pinpoint a fault is by activating individual components. Instead of guessing whether a bulb, motor, relay, or sensor is working, you can power it directly with the VDIAGTOOL V200 Pro. Your 2019 Ford F-150 radiator fan isn’t kicking in, and you’re unsure whether the problem lies in the fan itself, the relay, or the wiring. With the V200 Pro, you can send an activation signal directly to the fan while it’s still installed. If the fan spins, you know it’s functional and can shift your focus to relays or wiring. If it doesn’t, you’ve immediately identified the root cause. In this article, we’ll break down three different scenarios for using the V200 Pro to activate components Activating Components in Your Hand The tool allows you to test and activate handheld components such as bulbs, motors, or relays directly. This function helps verify component functionality before installation or during troubleshooting. To perform the test, follow these steps: (1) Connect the auxiliary ground lead to the negative terminal or ground side of the component.(2) Touch the probe tip to the positive terminal of the component. The display will show green, confirming continuity through the component. (3) Briefly press and release the power switch forward. If the display changes from green to red, the component is ready for activation. (4) Hold the power switch forward to deliver power to the component. Current will flow from the tool's probe through the component and back via the ground connection. For example, when testing a bulb: (1) Connect the ground clip to the bulb's base (negative side).(2) Touch the probe tip to the bulb's center contact (positive side). (3) Hold the power switch forward to illuminate the bulb. If the display turns off or the circuit breaker trips, the tool has detected an overload.This could happen because:(1) The contact you're probing is direct ground or negative voltage (2) The component being tested is short-circuited(3) It's a high-current component (e.g. starter motor)To reset, simply wait about 15 seconds for the breaker to cool down before continuing testing. Activating Components in The Vehicle To safely activate components while installed in the vehicle, first set the tool to DC Voltage mode and touch the probe tip to the component's positive terminal. The display will show green if proper ground continuity exists. Briefly press and release the power switch - if the display changes from green to red, it is safe to proceed with activation. If the display turns off or the protection activates immediately, this indicates an overload condition. This could happen for the following reasons: (1) The contact you are probing is a direct ground (2) The component you are testing is short-circuited(3) The component is a very high current component (i.e., starter motor)If the circuit breaker trips, wait 15 seconds for it to reset automatically. WARNING Improper voltage application may damage sensitive vehicle electronics. Always consult the manufacturer's wiring diagrams and diagnostic procedures before testing. NOTE To prolong switch life, press and hold the power switch before contacting the component. This directs any electrical arcing to the probe tip rather than the switch contacts. Activating Components w/Ground To activate components using ground connection, begin by setting the tool to DC Voltage mode and touching the probe tip to the component's negative terminal. The display will show red when a valid ground connection is detected. Briefly press and release the power switch back- ward - if the display changes from red to green, you may proceed with activation. If the display turns off or the protection activates, this indicates an overload condition. This could happen for the following reasons: (1) The contact you are probing is a direct positive voltage source(2) The component you are testing is short-circuited(3) The component is a very high current component (i.e., starter motor)If the circuit breaker trips, wait 15 seconds for it to reset automatically. WARNING When using this function, applying ground to a protected circuit may blow or trip the vehicle's fuse. Final Thoughts With the skills outlined in this guide, using the V200 Pro for component activation transforms vehicle electrical troubleshooting into a precise and efficient process. You can verify the functionality of key components like lights, motors, injectors, and relays safely, whether they are handheld or installed in the vehicle. This reduces uncertainty, prevents unnecessary replacements, and ensures accurate diagnostics. We welcome your feedback!

How to Use the V500 Pro Multimeter to Test Car Voltage, Resistance, Current, and Diodes
Multimeter – Your Onboard Electrical Tester The multimeter function, also known as a volt-ohm-milliammeter (VOM), is a powerful tool built into the V500 Pro. It allows you to measure key electrical properties such as voltage, resistance, current, and diodes in your vehicle. For example, if you own a 2016 Toyota Corolla and notice dim headlights, you can use the V500 Pro multimeter to measure the battery voltage. If the reading drops below 12V, it may indicate a weak battery that needs charging or replacement. With this feature, diagnosing electrical issues becomes faster, easier, and more accurate. The bottom of the interface is the functional area, from left to right are: Voltage, Resistance, Diode, Current, Frequency and Polarity. Kindly note: Please ensure correct wiring when making connections: connect positive to positive and negative to negative. Incorrect wiring may cause damage to the device. How to Operate the V500 Pro Multimeter You can press the "Left" or "Right" button to select the test mode. (1) Voltage (VDC): Connect the probe clip (auxiliary ground lead) to the negative pole, and connect the probe tip to the mea- sured voltage. DC voltage: In this mode, touch the probe tip to a circuit. The LCD will display the DC voltage with 0.1V resolution. AC voltage: In this mode, touch the probe tip to a circuit. The LCD will display the maximum voltage, minimum voltage, and frequency. (2) Resistance (OHM): Connect the probe clip (auxiliary ground lead) to one side of the Resistance being measured, and the probe tip to the other side. In this mode, touch the probe tip to a circuit. The LCD will show the resis- tance between the probe tip and the auxiliary ground lead. (3) Diode (DIO): Connect the probe clip (auxiliary ground lead) to one side of the Diode being measured, and the probe tip to the other side. Meanwhile it will display the voltage and show Positive and Negative of Diode. In this mode: • Connect the probe tip to the positive terminal of the diode.• Connect the auxiliary ground lead to the negative terminal.• The screen will display the forward voltage drop, indicating correct forward bias.•If you reverse the connections (tip to negative, ground lead to positive), the screen will not display a voltage, indicating correct reverse bias. (4) Current (AMP): The probe is connected in series in the circuit under test, it will display the current value.(5) Frequency (HZ): Display the frequency of the measured signal and duty cycle value. (6) Polarity: Display whether the current measured line is positive or negative. For more: NOTE: When testing the current, make sure the wires are in series connection, not in parallel connection. If they are in parallel connection, it will cause the device to trigger the overload protection and then restart.
