After a vehicle has entered a sleep mode, the disclosed method places the vehicle monitoring system into longer and longer nap periods provided the monitoring system does not receive a wake-up signal from one of a plurality of vehicle subsystems. During the nap periods, the monitoring system requires a reduced amount of operating power thereby decreasing the parasitic current drain on the battery during the sleep mode.
