Wake-Up and Sleep Modes
Wake-up signals are signals which turn on the BCM. Once active, the BCM begins monitoring and controlling the system functions listed above. With the ignition switch in the OFF position, the BCM ceases control of the system functions after a 10 minute period. This is the sleep mode. During the sleep mode the BCM monitors several circuits for changes in status. The BCM wakes up when a change is detected in any of the following inputs:^ The courtesy lamps
^ The remote keyless entry system
^ The ignition switch
^ The park lamps
^ The headlamps
^ The side door locks
^ The rear compartment lid ajar indication switch
^ The ignition key lock cylinder
^ The theft deterrent shock sensor
