About

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 β€” using your car's own live data. WHY DIAGNOVA IS DIFFERENT β€’ Guided live diagnosis β€” 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. β€’ Safe-to-Drive verdict β€” A clear, conservative call β€” stop now, drive with caution, or you're OK β€” based on misfire severity, temperature, battery and code criticality. β€’ Pre-MIL prediction β€” Reads Mode 06 on-board monitor trends to warn you before the check-engine light actually comes on. β€’ Second-Opinion certificate β€” 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. β€’ Multi-code root-cause correlation β€” When several codes fire together, DiagNova spots the single underlying fault that explains them. β€’ Plain-language symptom search β€” Describe the problem in your own words and jump straight to the right playbook. EVERYTHING FROM ONE CHEAP ADAPTER β€’ Stored, pending and permanent DTCs (Mode 03 / 07 / 0A). β€’ Mode 06 on-board monitor test results and Mode 09 vehicle info (CALID / CVN / IUMPR). β€’ Freeze-frame analysis β€” ranks causes from the snapshot saved when the fault triggered, no driving needed. β€’ Per-cylinder misfire localization. β€’ 97 DTC playbooks and 22 repair playbooks β€” and it learns: your repair outcomes refine the next diagnosis. EVERYDAY DASHBOARD β€’ Live vitals strip β€” coolant, battery, fuel level, intake air, in real time. β€’ Last-scan summary and session compare (DTC diff + PID trend charts). β€’ Threshold alerts (coolant, fuel trim, battery) and readiness monitors for inspection. β€’ VIN decoder, trip fuel-cost tracker, maintenance log with service reminders. β€’ Adapter health check β€” detects common ELM327 clones and connection quality. β€’ PDF / CSV export. FREE, PRIVATE, LOCAL-FIRST β€’ 100% free β€” no subscription, no ads. β€’ No accounts, no cloud, no tracking, no analytics. β€’ All data stays on your device in a local SQLite database. Anything shared is strictly opt-in. WORKS WITH β€’ Any ELM327-compatible adapter β€” 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.
