Find out why the check engine light is on, clear fault codes, watch live data, unlock hidden features. ▸ OBD2 DIAGNOSTICS • FAULT CODE READING AND CLEARING (DTC) Read and clear OBD2 fault codes — standard P-codes plus manufacturer-specific B, C and U codes. Engine, transmission, ABS, airbags and body modules in a single scan. Descriptions in plain language. • AI FAULT ANALYSIS What does "P0420" mean? Built-in AI explains the likely cause, urgency and what to check first — no jargon. • LIVE ENGINE ANALYSIS Measure fuel trim and oxygen sensor response at idle and under load; the app diagnoses vacuum leaks, fuel supply issues and sensor faults from the numbers. • USED CAR CHECK AND INSPECTION READINESS Were fault codes cleared before sale? Permanent fault codes, readiness monitors and distance driven since codes were cleared on one screen. Mode 06 tests give early warning before a fault code is set. ▸ LIVE DATA AND GAUGES • DIGITAL GAUGE PANEL Track RPM, coolant temperature, oil temperature, boost pressure, fuel trim and battery voltage in real time. Design your own gauges, record drives, export OBD2 logs. • TRIP COMPUTER AND PERFORMANCE TEST Real-time and average fuel consumption, trip cost, distance and speed summary. Measure 0-100 km/h, quarter-mile and braking tests on closed track. • BATTERY, HYBRID AND DPF HEALTH Check battery health from the voltage drop while cranking. Battery status on hybrids and EVs; DPF differential pressure, regeneration status and AdBlue level on diesels. ▸ SERVICE RESET AND MAINTENANCE • OIL, EPB, DPF, SAS AND TPMS RESET Oil change reset, electric park brake (EPB) service mode, DPF regeneration, steering angle sensor (SAS) calibration and TPMS reset — with pre-flight RPM and voltage checks. • ACTUATOR TEST AND EXTENDED SENSORS On supported models, start and stop actuators directly from the app. Read vehicle-specific signals: charge percentage, module temperatures, oil life and more beyond standard OBD2. ▸ ECU CODING AND HIDDEN FEATURES • CODING Read and back up ECU coding data, then switch hidden factory features on or off: mirror folding on lock, seatbelt chime, gauge sweep, headlight behavior. Expert Mode offers direct hex/byte access. • BRAND SUPPORT The most complete coding support is on BMW and MINI. Long coding and adaptation on VW, Audi, Skoda, Seat and Cupra; telecoding on Peugeot, Citroën, DS and Opel; module coding on Ford, Fiat, Alfa Romeo, Jeep, Renault and Dacia; reading and analysis on Hyundai, Kia, Toyota and many more brands. Options vary by model. ▸ MORE • MOTORCYCLE AND TRUCK DIAGNOSIS K-line fault diagnosis and live data on motorcycles; active and historical faults plus live values over J1939 on trucks and buses. • REMOTE SUPPORT Open a support session from within the app; our team inspects your vehicle live through your phone. • 32 LANGUAGES Interface, fault code descriptions and coding labels in 32 languages. • COMPATIBILITY All OBD2-compliant vehicles (gasoline 2001+, diesel 2004+); quality ELM327 Bluetooth and Wi-Fi adapters. ▪ Coding and service resets write data to control modules.
