## What is TScanPro?

T‑Scan Pro turns a compatible ELM327 Bluetooth Low Energy or Wi‑Fi adapter into a focused vehicle dashboard and diagnostics companion.

Built around the 2019 Toyota LandCruiser Prado 150 2.8L turbo-diesel, T‑Scan Pro combines live telemetry, trip recording and Prado-specific diagnostic guidance in one clear interface.

LIVE VEHICLE DASHBOARD
• View speed, RPM, coolant temperature, intake temperature, boost, voltage, engine load, fuel rate and other readings when supported by the connected ECU.
• Build and rearrange the dashboard around the data that matters to you.
• Use the included demo simulator to explore the app without an adapter.

HONEST DATA COMPATIBILITY
• Supported Data Scan checks the ECU’s advertised OBD‑II capability maps.
• Unsupported or unverified values are clearly shown as unavailable instead of being displayed as invented zeroes.
• Diesel-specific petrol PIDs such as STFT, LTFT and conventional O2 readings are identified appropriately.

PRADO DIAGNOSTICS
• Organised coverage for engine and diesel emissions, DPF and exhaust, fuel and injectors, turbo and intake, transmission, 4WD, ABS/VSC and body or safety modules.
• Read trouble codes, emissions readiness and available live data.
• Run read-only Prado discovery to identify available modules and data safely.
• Export diagnostic reports for your records or workshop.

VEHICLE HEALTH
• See a health score with evidence, confidence and prioritised findings.
• Track maintenance items and retain historical reports.

SMART ALERTS AND TRIPS
• Configure coolant, boost and low-voltage warnings, including background notifications while the adapter remains connected.
• Record GPS routes, trip history and live telemetry.
• Export trip data and keep automatic backups in iCloud Drive.

Actual readings depend on the vehicle, ECU calibration and adapter. Toyota-enhanced values such as DPF soot load, differential pressure, regeneration state, exhaust-gas temperatures and injector feedback require verified support for the connected vehicle and are never fabricated. T‑Scan Pro is a diagnostic companion and does not replace professional inspection or repair advice.
