To check the engine light without a scanner, you can try the “key dance” method, which involves turning your ignition key on and off in a specific sequence (e.g., “On-Off-On-Off-On”) to make the engine light blink. The blinking pattern can indicate specific diagnostic trouble codes (DTCs). However, this technique’s effectiveness and availability might vary significantly across different vehicle makes and models, and it may not work on newer vehicles. For a more accurate diagnosis, some vehicles allow you to access basic DTCs through the dashboard display by navigating the vehicle’s onboard menus. It’s also worth noting that many auto parts stores offer free scanning services. While these alternatives can provide some insights, they often lack the detailed diagnostics available from a professional scan tool. For a thorough check, consulting a mechanic or investing in an inexpensive OBD-II scanner for a comprehensive diagnosis is advisable.
