CHECK ENGINE LIGHT ON?
DIAGNOSTICS
Read your OBD fault code or tell us what the car is doing — we'll explain the problem and show you the parts that fix it. Browse the fault code library → Dashboard warning lights →
From your OBD scanner — codes look like P0301, C1234, B0025.
OR SCAN AUTOMATICALLY
Plug the USB ELM327 cable into the car and the laptop, ignition on, and pick it when the browser asks.
LIVE SENSORS
Engine running, dongle plugged in — watch RPM, coolant, speed, throttle and battery in real time.

SERVICE RESETS
Pick a reset and your vehicle — we'll give you the exact manual procedure where it can be done at the car, and tell you honestly when it needs a workshop tool. The Bluetooth dongle can't write to the ECU, so these are guided resets, not remote commands.
