Does anyone know if the ECU in automobiles monitors the base current of transistors and sets code if it is more or less than some pre-set value stored in the ECU. Just curious. Also, if one transistor is driven by another such one transistor(Q2) is driven by the collector output voltage of the other(Q1). Q2 switches on when Q1 is off. Let's say that the base resistor was badly chosen( too low for instance). Can that have devasting effects on Q1. If Q2 burns, what will mostly happen to Q1 ?What is the worst case scenario? Thank you in advance.
