3-in-1 Automotive Diagnostic System

Stop Guessing.
Find Electrical Faults Faster.

Test circuits, identify polarity, activate compatible components and diagnose common automotive relays with one powerful tool.

Real-Time VoltageInstant PolarityRelay TestingComponent Activation

Too Many Tools. Too Much Time.

Stop Switching Between Multiple Testers

Traditional electrical diagnosis often means tangled leads, repeated setup and constant switching between meters, probes and relay tools.

One organized diagnostic system

Spend less time setting up tools and more time identifying the actual fault.

One Tool. Complete Control.

Save Time, Find Faults Faster and Repair With Confidence

Upgrade your toolbox with an all-in-one diagnostic system built to make automotive electrical troubleshooting faster, cleaner and more controlled.

Stop Guessing. Start Diagnosing.

Find the Fault Before You Replace the Part

Carry fewer tools, get clearer answers and take control of your next automotive electrical repair.

TEST SMARTER • REPAIR BETTER • DRIVE CONFIDENT

Does it work with both 12V and 24V vehicles?

Yes. It is designed for compatible 12V and 24V DC vehicle electrical systems.

Can it test automotive relays?

It includes an integrated testing area for selected common 4-pin and 5-pin automotive relays. Always verify the relay layout before testing.

Can it power a fan, light or motor?

It can apply positive or negative battery current to compatible DC components for diagnostic purposes. Confirm the component rating first.

Does it replace a professional multimeter?

It replaces several common automotive diagnostic tools, but it is not intended to replace every function of a full multimeter, oscilloscope or manufacturer-specific scan tool.
