What happens when the ECU of a car goes bad?

Car batteries have electronic cells which need to function in order for the ECU to function. If any of the cells in your car battery are dead, then your ECU is going to fail soon afterward. Once all the cells are dead, your entire vehicle won’t be able to function either. You won’t be able to even start your vehicle and get the engine running.

How is the ECU dependent on the drivetrain?

The engine and drivetrain are the most dependent on the ECU. Through a numerous array of electronic sensors, chips, and components within the vehicle, the ECU can transmit data feedback to the engine. The nature of this feedback will determine which function the engine will perform next.
