How does the ESC work on a car?
Under heavy load, the module will advance the timing to increase power and will retard it at low throttle and cruising speeds in order to maximize efficiency. The ESC module makes these changes automatically and smoothly, almost to the point where they are virtually unnoticeable to the driver.
What happens when an ESC module goes bad?
Car not starting or engine not sparking Another common symptom of a faulty ESC module is a no start, or no spark condition.
