Autozond: OBD2 scanner ELM327

Autozond turns your phone into an OBD2 scanner and a full car diagnostic tool. Plug in an ELM327 adapter and see what a workshop normally charges you for: engine fault codes, live sensor data and the real mileage. ━━━ MILEAGE CHECK: SPOTS A ROLLED-BACK ODOMETER ━━━ The app reads the odometer from several control units at once — the instrument cluster, the engine ECU, the body computer — and compares them against each other. A mismatch between modules means the mileage was rolled back. It also checks the mileage recorded when old fault codes were stored: that value cannot exceed the current reading. 23 makes covered. Invaluable when buying a used car: odometer fraud shows up before the deal, not after. ━━━ FAULT CODES AND CHECK ENGINE ━━━ • Read fault codes and clear them, turn off the check engine light • Offline database of 10,649 codes • Confirmed, pending and permanent codes (modes 03/07/0A) • Extended scan across all modules — transmission, ABS, SRS, body, climate (UDS protocol, 44 makes) • Freeze Frame — engine parameters at the moment the code was stored • Severity colour scale: what to fix now and what can wait ━━━ LIVE DATA ━━━ • Graph up to 5 parameters at once, with zoom, pause and a time cursor • 30 standard sensors: RPM, oxygen sensors, fuel trims, intake pressure, MAF, temperatures • Data from non-engine modules: ABS wheel speeds, transmission oil temperature, battery state • A dashboard you lay out yourself: dial and arc gauges, full screen, head-up display mode (HUD) ━━━ TRIP COMPUTER ━━━ Real-time fuel consumption, consumption per trip, trip cost, average speed, time in motion. Recording continues in the background. Trip log with graphs and CSV export. ━━━ PERFORMANCE TEST ━━━ 0–60 mph, 0–100 km/h, quarter mile and eighth mile, peak horsepower and a torque curve over RPM — a dyno in your pocket. ━━━ VEHICLE REPORT AS PDF ━━━ One pass is a full engine and systems diagnostic: fault codes, emissions readiness, on-board catalyst and oxygen sensor tests, ECU firmware identifiers (reflashes and chip tuning become visible), and the odometer cross-check. The result is a PDF you can send to a seller, a mechanic or a buyer. ━━━ SERVICE INTERVAL RESET ━━━ Step-by-step procedures for Honda, Toyota, VW, Renault, BMW, Hyundai and Nissan. The app identifies the make from the VIN. ━━━ TRY IT WITHOUT AN ADAPTER ━━━ The built-in demo mode shows every feature on invented data — you do not have to buy an adapter to look around first. ━━━ ADAPTERS ━━━ Works with any ELM327 scanner: OBD2 Bluetooth, Bluetooth LE and Wi-Fi adapters. Automatic protocol detection: CAN, ISO 9141, KWP2000, K-Line. Slow buses found in Russian and Japanese-market cars are supported specifically. ━━━ COMPATIBILITY ━━━ Lada, UAZ, Renault and Dacia, Volkswagen, Audi, Skoda, Seat, Toyota, Lexus, Honda, Nissan, Infiniti, Hyundai, Kia, Ford, Chevrolet, Opel, BMW, Mini, Mercedes-Benz, Volvo, Mazda, Mitsubishi, Subaru, Suzuki, Peugeot, Citroen, Fiat, Alfa Romeo, Jaguar, Land Rover, Porsche, Chrysler, Jeep, Dodge, Haval, Chery, Geely, Changan, MG, Lifan, SsangYong, Isuzu — and any car built to the OBD-II standard (petrol from 2001, diesel from 2004 in Europe; from 1996 in the US). ━━━ WHAT IS FREE ━━━ The code reference with no limit, reading and clearing fault codes, odometer from the standard sensor, trip computer, acceleration test, trip log, service reset procedures, demo mode, two dashboard gauges and three sensors on the graph. ━━━ WHAT PRO UNLOCKS ━━━ The odometer cross-check across all control units, the extended module scan, non-engine module data, the full report with PDF export, all 30 sensors on the graph and an unlimited dashboard. One-time purchase, no subscription, no ads. The app never writes to control units — it only reads and clears fault codes. For complex faults, see a professional.
