Monitored Loads
In order to minimize any battery rundown, the
Body Control Module (BCM) can detect if certain electrical loads have been left on. When the BCM detects that the ignition has been cycled to the OFF position, the BCM immediately checks the status of the load monitor input. If the BCM detects that a load is present (ground on CKT 640), the BCM turns ON the load monitor
relay for
15 minutes. If after
15 minutes the BCM still recognizes that a load is present, the BCM will turn OFF the relay, removing the battery voltage from the loads. The BCM continues to monitor this circuit for a switch transition. The BCM will again turn ON the relay for
15 minutes if a switch transition exists.
