DiagnosePro V500 — OBD2 Scanner & Fault Code Reader
Stop guessing. Start knowing. DiagnosePro V500
A professional OBD2 scanner and fault code reader that reads and clears engine codes, monitors live data, tests battery voltage and covers 99% of vehicles made after 1996 — all in one pocket-sized tool.

That check engine light has been staring at you long enough.
Without a car code reader, every warning light is a mystery. You either ignore it and risk serious damage, or pay a mechanic $100+ just to read a code this OBD2 diagnostic tool reads in seconds — for free, every time.
The problems every driver faces
Check engine light on with no idea why
Without an engine light scanner, every warning is a mystery. You ignore it, worry about it, or pay $100+ at the shop — just to hear it's something minor.
Paying mechanics to do what you could do yourself
A loose gas cap. A sensor reset. Simple fixes you could have handled with a car code reader in under two minutes — no appointment, no waiting, no bill.
No warning before the battery dies
A weak battery gives no warning until it's already dead. Real-time voltage monitoring flags the problem before you're stranded in a car park at midnight.
Professional diagnostics. Zero mechanical knowledge needed.
Every feature built for drivers who want answers, not guesswork.
Read & clear engine fault codes instantly
Plug into the OBD2 port and get a plain-English explanation of every fault code. Perform a check engine light reset yourself once the issue is resolved — no mechanic needed.
Real-time live data stream
Monitor engine coolant temp, RPM, vehicle speed and calculated load value live with real-time curve graphs. See exactly how your engine is performing at all times.
Battery voltage testing
Measure real-time battery voltage, view the voltage curve and assess battery life. Know your battery is weakening before it leaves you stranded.
Built-in DTC code library
Look up the meaning of any fault code directly on the device — no phone, no internet, no guessing. Thousands of codes explained in plain language on screen.
I/M readiness & emissions check
Check whether your vehicle is ready for emissions testing before you show up to the station. Pass first time, every time.
Simple enough for any driver
Plug in, power on, press DTC. A dedicated fault code shortcut key, colour screen menu and intuitive button layout mean zero learning curve.
Everything a professional OBD2 diagnostic tool does.
At a fraction of what the dealership charges to run the same checks.

Real-time engine data. Always in the picture.
This OBD2 scanner streams live engine data so you can monitor your vehicle's health in real time — not just when something goes wrong. Watch RPM, coolant temperature, speed and load value as live curve graphs on screen.
Know your battery's health before it fails you.
The built-in battery test function measures real-time voltage, displays a voltage curve and assesses remaining battery life. If your battery is weakening, the DiagnosePro V500 tells you — before it leaves you stranded.
