## What is FaultScan?

Check engine light on? Find out what it means in seconds.

FaultScan turns any ELM327 Bluetooth adapter into a plain-English car diagnostic tool. Plug it in, connect, and get a clear verdict: keep driving, drive to a workshop soon, or stop. No subscription. No account. No paywalled answers.

WHAT YOU GET

• Full fault code scan — stored, pending and permanent codes (mode 03/07/0A)
• Plain-English explanations for 1,100+ generic codes, with common causes
• Code lookup — search the full library by code number or description, no scan needed
• Clear verdicts — know if your car is safe to drive
• Freeze frame — see exactly what the engine was doing when the fault happened
• Live dashboard — RPM, speed, coolant temperature, battery voltage, throttle, intake air
• Emission readiness — check monitors before your inspection
• VIN reading
• Scan history — your last 30 scans, stored only on your device
• Share a scan report as text with your mechanic

WORKS WITH YOUR ADAPTER

Any ELM327-compatible Bluetooth (BLE) adapter — Vgate iCar Pro, IOS-Vlink and most generic adapters. No dongle lock-in.

PRIVATE BY DESIGN

Your car data never leaves your device. No account, no tracking of vehicle data, no cloud. Scans are stored locally and only shared if you choose to.

FREE & HONEST

Supported by unobtrusive ads. Every feature is free — no premium tier, no trial limits.

Note: FaultScan reads and clears diagnostic codes. For repair decisions, always consult a qualified mechanic.
