The P1550 fault code refers to the Battery Current Sensor Circuit RangePerformance. This code is related to the power generation voltage variable control system in the vehicle. The purpose of this system is to reduce fuel consumption by decreasing the engine load caused by the generator’s power generation.

To monitor the charging and discharging current of the battery, a battery current sensor is installed on the negative terminal of the battery cable.

The sensor provides a signal to the Engine Control Module (ECM), which determines whether or not the power generation voltage variable control should be activated. When the power generation voltage variable control is engaged, the ECM calculates the target power generation voltage based on the sensor signal. The ECM then sends this calculated value as the power generation command to the Intelligent Power Distribution Module Engine Room (IPDM ER).

The P1550 fault code indicates that there is an issue with the battery current sensor circuit, specifically with its range or performance.

This fault code should be diagnosed and repaired to ensure proper functioning of the power generation voltage variable control system and optimize fuel consumption.

What are the possible causes of the automobile fault code P1550?

If you see the engine light or service engine soon warning light on, the fault code P1550 could be the culprit.
