Checking if the ECU is receiving power or ground when the car won't start.
Follow the positive terminal of the input capacitor (typically 10µF–22µF, rated for 25V or more). That capacitor connects directly to . me745 pinout free
Here I provide you with some extra formats, you can use them if you want. Checking if the ECU is receiving power or
If you provide the (e.g., 5-pin SOT-23) and the circuit context (e.g., "on a 12V to 5V converter board"), a more precise identification — and thus a free pinout — becomes possible. me745 pinout free
