General Information: General Description

Many control units have been applied to vehicles as they become more electronic. These units control their own systems based on information from diverse sensors. Therefore, the necessity of using diverse sensor information, and the importance of stable power supply, are becoming more critical. The Battery Sensor is mounted on the battery (-) terminal. It transmits battery voltage, current, and temperature information to the ECM (PCM) . The ECM (PCM) controls the generating voltage by duty cycle based on these signals.
