DTC P1550 Battery Current Sensor Circuit; DTC P1551 Battery Current Sensor Circuit Low; DTC P1552 Battery Current Sensor Circuit High: Description
The battery current sensor installed on the positive (+) battery terminal detects the amount of current supplied from the generator.
The battery current sensor changes current to voltage (at the positive (+) battery terminal) and sends it to the ECM. The ECM controls the voltage of the generator based on the signals from the battery current sensor.
