What Drivers Are Saying
Found It in Minutes
"Light came on, I plugged this in, and it told me exactly what was wrong in under five minutes. Saved me a trip to the shop."
Knoxville, TN
Love That It Needs No Batteries
"Powers right off the car. Pull it out of the glovebox any time and it just works. Huge plus."
Mesa, AZ
Easy Even for Me
"I'm no mechanic. Plugged it in, read the code, cleared the light. Couldn't be simpler."
Lansing, MI
Plug In. Read Your Codes.
A simple setup for drivers who want answers before they pay for repairs.
From box to answer in minutes.
1
Unbox It
Open the package and your V500 is ready to go, no charging needed.
2
Find the Port
Locate the 16-pin OBD2 port under your dash, driver's side near the steering column.
3
Plug It In
Insert the connector firmly. No tools required.
4
Turn The Key To ON
The screen powers up on its own — no batteries to mess with.
5
Read / Clear Codes
Use the arrow keys to choose OBD/EOBD → Read Codes and press OK to see the problem, or Erase Codes to clear the light.
6
Unplug & Store
Pull it out, toss it in the glovebox, and you're set for next time.

Why Drivers Keep It in the Glovebox
• Reads and clears check-engine codes in seconds
• Built-in battery voltage tester — not just a code reader
• Powers from your car — no batteries, no charging
• Works on OBD2 vehicles 1996 and newer, 8 languages
• Simple enough for a first-timer, useful enough for a pro
Why the V500 Stands Out
A simpler, cheaper way to know exactly what your car is telling you.
THE V500 ✅
- Read your own codes in ~30 seconds
- Powers from your car — no batteries
- Battery voltage test built in
- Plain-language code library
- Pocket-size — lives in your glovebox
THE SHOP / OTHERS ❌
- Pay $100–$150 just for a diagnostic
- Needs charging or replacement batteries
- Code-only, no charging-system check
- Cryptic codes you have to Google
- Bulky shop equipment you don't own
VS
Virtually any gas vehicle built in 1996 or later and sold in the US — that's when the OBD2 standard became mandatory. Look for the 16-pin port under your dash.
No. The V500 powers itself from your car the moment you plug in.
Yes — use Erase Codes. If the underlying problem isn't fixed, the light will return; the V500 tells you what to fix so it stays off.
No. The V500 reads engine/powertrain (emissions) codes, live data and voltage. ABS and airbag systems need a dealer-level tool.
It reads standard OBD2 generic codes; coverage is strongest on gas vehicles, and diesel/hybrid support varies by model.
Not at all. Plug in, turn the key, hit Read Codes. Built for everyday drivers, not just mechanics.

Very helpful diagnosis but I thought the OBD was suppose to be able to clear check engine lights. The OBD said my catalytic converter fuel mix was too rich so how do I clear the check engine light?
T
Fantastic gift for my son in law thank you!
