DTC P0AC0 (65): Battery Current Sensor 1 Circuit Malfunction: General Description

The motor control module (MCM) calculates the offset value of the battery current sensor during no voltage condition of the battery module immediately after the ignition switch is turned to ON (II). The MCM converts (analog/digital conversion) the ISOC signal input voltage and when the difference between the maximum value and the minimum value of eight continuous inputs are within 0.015 V, the average value of eight battery current sensor inputs are calculated. When the battery current sensor average value is out of a specified range, a malfunction is detected and a DTC is stored.
