The battery condition monitor module communicates with the leak sensor. If the battery condition monitor module does not receive signals from the leak sensor for a set time, or when the information sent from the leak sensor is abnormal and this condition continues for a specified time, the battery condition monitor module detects a malfunction and stores a DTC.
