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 on any of the following inputs:
^ Remote keyless entry system
^ Door ajar switches
^ Ignition switch
^ Side door locks
^ Light control switches
^ Rear compartment lid ajar indication switch
^ Ignition key lock cylinder
^ Theft deterrent shock sensor.
