Many control units have applied to vehicle as it becomes more eletrolnical. These units control their own system based on information from diverse sensors. Therefore necessity of common use of diverse sensor information and importance of stable power supply are gathering strength. Battery sensor is mounted on battery (-) terminal. It transmits battery voltage, current, temperature information to ECM/PCM. ECM/PCM controls generating voltage by duty cycle based on these signals.
ECM/PCM sets this code when the battery charging current from battery sensor is too low.
