Question
What is the role of injector driver MOSFET thermal stress diagnosis?
Answer
It detects overheating MOSFETs causing injector control failures.
Explain
Injector driver MOSFETs handle high current; thermal stress degrades performance. CHEPQ oscilloscopes monitor MOSFET junction temperature (via voltage drop), detect overheating, and identify inadequate heat dissipation or excessive current draw. This prevents driver circuit failures, ensuring reliable injector control.
