The V519 is the 2025 upgraded model engineered to deliver professional-grade diagnostics at home or in the shop. Whether you're dealing with a check engine light or want to dive deeper into your vehicle's performance, the V519 empowers you with real-time, precision data and full OBD2 + CAN protocol support.
Unlock Deeper Vehicle Insights Than Basic Code Readers
The V519 isn't just an OBD2 scanner – it's your master key to advanced gasoline engine diagnostics. Engineered for mechanics and savvy DIYers, it transforms your vehicle's OBDII port into a lab-grade analysis hub, tackling everything from persistent check engine lights to pre-smog test prep with unmatched precision.
All-in-One Diagnostics – From Fault Codes to Smog Check Readiness
Read and clear engine codes, stream live sensor data, capture freeze frame information, and check I/M readiness for emissions testing. Built-in battery voltage testing helps you detect early signs of battery failure by monitoring voltage before and after ignition.
Smog Test Dominance
Clear “not ready” monitors before emissions testing, verify catalyst efficiency, and graph EVAP system pressure to pass inspections confidently.
Live Data Mastery
Compare upstream/downstream O2 sensor voltages, track long-term fuel trims, and monitor spark advance timing to solve hesitation, stalling, or rough-idle issues with precision diagnostics.
Battery Defense System
Measure voltage drop during cranking (≤9.6V indicates battery replacement) and diagnose parasitic drains using trend graphs — a key feature for cold starts and intermittent issues.
Mode 6 Decoder Ring
Access manufacturer-specific tests like cylinder-specific misfire counts or fuel injector balance – features completely absent in sub-$50 code readers.
Standalone Handheld Unit – No App or Bluetooth Required
With its bright 2.8” full-color screen and intuitive interface, the V519 offers true plug-and-play operation. No smartphones, apps, or downloads are needed — simply connect and scan within seconds.
Massive Built-in DTC Library
Instantly see over 40,000 diagnostic trouble codes with clear definitions – no external lookup required. Multi-language support (10 languages) ensures ease of use worldwide.
Lifetime Free Updates + PC Connectivity
The included USB Type-C cable allows free lifetime software updates, keeping your scanner compatible with newer vehicles. Export diagnostic reports directly to your PC to build a repair history or share with your mechanic.
No Hidden Costs – Just Clear Results
Forget subscription fees or in-app purchases. The V519 gives you everything upfront, including emissions prep, battery tests, real-time graphing, and access to full OBDII Modes 1–10, including advanced Mode 6 & Mode 8.
Perfect for Everyone
Whether you're a DIY enthusiast, a weekend warrior, a professional technician, or just want to avoid surprise repair bills, the V519 gives you the power to understand and maintain your vehicle with confidence.
