DiagNova

DiagNova turns any ELM327-compatible OBD2 adapter into a guided diagnostic assistant. Most scanners stop at "here are your codes." DiagNova tells you the likely cause, whether the car is safe to drive, and walks you through the fix — using your car's own live data. WHY DIAGNOVA IS DIFFERENT • Guided live diagnosis — A decision-tree engine reads your live sensor data (RPM, fuel trims, MAF, O2, coolant) and ranks the most likely causes with confidence scores. No more swapping parts on a guess. • Safe-to-Drive verdict — A clear, conservative call — stop now, drive with caution, or you're OK — based on misfire severity, temperature, battery and code criticality. • Pre-MIL prediction — Reads Mode 06 on-board monitor trends to warn you before the check-engine light actually comes on. • Second-Opinion certificate — Export a shareable PDF that proves the diagnosis with the live data behind it. Bring it to the mechanic so you don't get upsold. • Multi-code root-cause correlation — When several codes fire together, DiagNova spots the single underlying fault that explains them. • Plain-language symptom search — Describe the problem in your own words and jump straight to the right playbook. EVERYTHING FROM ONE CHEAP ADAPTER • Stored, pending and permanent DTCs (Mode 03 / 07 / 0A). • Mode 06 on-board monitor test results and Mode 09 vehicle info (CALID / CVN / IUMPR). • Freeze-frame analysis — ranks causes from the snapshot saved when the fault triggered, no driving needed. • Per-cylinder misfire localization. • 97 DTC playbooks and 22 repair playbooks — and it learns: your repair outcomes refine the next diagnosis. EVERYDAY DASHBOARD • Live vitals strip — coolant, battery, fuel level, intake air, in real time. • Last-scan summary and session compare (DTC diff + PID trend charts). • Threshold alerts (coolant, fuel trim, battery) and readiness monitors for inspection. • VIN decoder, trip fuel-cost tracker, maintenance log with service reminders. • Adapter health check — detects common ELM327 clones and connection quality. • PDF / CSV export. FREE, PRIVATE, LOCAL-FIRST • 100% free — no subscription, no ads. • No accounts, no cloud, no tracking, no analytics. • All data stays on your device in a local SQLite database. Anything shared is strictly opt-in. WORKS WITH • Any ELM327-compatible adapter — BLE (Bluetooth Low Energy) and WiFi. DISCLAIMER DiagNova is a diagnostic aid, not a replacement for professional service. Always follow your vehicle manufacturer's repair procedures and observe safety warnings.
