Never use an old-school incandescent test light on ECU circuits. Test lights draw too much current and can overload delicate 5V sensor circuits. Always use a high-impedance Digital Multimeter to safely check voltages.
Fortunately, there are several high-quality, completely free resources available online. This comprehensive guide highlights the top 30 free ECU datasheet platforms, details how to read standard pinout schematics, and outlines safe practices for testing control modules.
