Description
The power generation voltage variable control enables fuel consumption to be decreased by reducing the engine load which is caused by the power generation of the generator. The battery current sensor is installed to the battery cable at the negative terminal. The sensor measures the charging/discharging current of the battery.
Based on the sensor signal, ECM judges whether or not the power generation voltage variable control is performed. When performing the power generation voltage variable control, ECM calculates the target power generation voltage based on the sensor signal. And ECM sends the calculated value as the power generation command value to IPDM E/R. For the details of the power generation voltage variable control, refer to CHG-8, "System Description".
CAUTION: Never connect the electrical component or the ground wire directly to the battery terminal. The connection causes the malfunction of the power generation voltage variable control, and then the battery discharge may occur.

NOTE: If DTC P1554 is displayed with DTC P0643, first perform the trouble diagnosis for DTC P0643. Refer to EC-394, "DTC Logic".
DTC CONFIRMATION PROCEDURE
1.PERFORM COMPONENT FUNCTION CHECK
Perform component function check. Refer to EC-423, "Component Function Check".
NOTE: Use component function check to check the overall function of the battery current sensor circuit. During this check, a 1st trip DTC might not be confirmed.
Component Function Check
1.PRECONDITIONING
TESTING CONDITION:
2.PERFORM COMPONENT FUNCTION CHECK
With CONSULT
"BAT CUR SEN" should be above 2,300 mV at least once.
Without CONSULT
Diagnosis Procedure
1.CHECK GROUND CONNECTION
2.CHECK BATTERY CURRENT SENSOR POWER SUPPLY CIRCUIT
3.CHECK BATTERY CURRENT SENSOR GROUND CIRCUIT FOR OPEN AND SHORT
4.CHECK BATTERY CURRENT SENSOR INPUT SIGNAL CIRCUIT FOR OPEN AND SHORT
5.CHECK BATTERY CURRENT SENSOR
6.CHECK INTERMITTENT INCIDENT
Component Inspection
1.CHECK BATTERY CURRENT SENSOR
