Title: A25A-FKS (BATTERY / CHARGING): CHARGING SYSTEM: P058A01; Battery Monitor Module General Electrical Failure; 2019 - 2023 MY RAV4 [11/2018 - 10/2023]

DTC

P058A01

Battery Monitor Module General Electrical Failure

DESCRIPTION

The battery state sensor assembly detects the voltage, current and temperature of the battery. The battery state sensor assembly calculates State of Charge (SOC) based on the voltage and current of the battery and sends it to the ECM. Based on the signals received, the ECM adjusts the charging voltage of the generator assembly.

The battery state sensor assembly calculates the battery temperature based on changes in resistance of a built-in thermistor and sends it to the ECM. The ECM reduces the amount of charging current based on this signal in order to protect the battery.

DTC No.
