BlinkCode APP
BlinkCode is a diagnostic tool that uses your phone's camera to decode engine fault codes on most 1980s–1990s vehicles (OBD1). It reads and analyzes the blinking pattern of the check engine light to display error codes.
Set your car's ECU into fault code reading mode (e.g., short two pins in the diagnostic connector).
🔧 Tip: Check your workshop manual or online forums to identify the correct pins for your vehicle model.
The check engine light will blink in a pattern that the app analyzes.
