B1527 BUICK MeaningComponents most likely to cause a parasitic draw on the battery of the vehicle are switches, relays, and control modules. After the ignition is turned OFF the control modules will begin to go to sleep (shut OFF). All control modules do not go to sleep at the same time, some, like the Heating, Ventilation, and Air-Conditioning (HVAC) and body control modules, may take up to 30 min or longer after turning the ignition off before going to sleep. Others such as the ON Star and keyless entry control modules may periodically wake up then go back to sleep. These are all normal conditions. The Body Control Module (BCM) monitors the state of charge of the electrical system. If the BCM senses that the state of charge at ignition On is 30% lower than what it was when the engine was running.
