Wake-Up & Sleep Functions

Wake-up and sleep modes are used to decrease parasitic draw on battery when ignition is off, . In sleep mode, multiplex control unit stops communication and CPU control functions when system operation is not needed. When any monitored system or switch operates, such as a door being unlocked, related multiplex control unit will change from sleep function to wake-up function. A wake-up signal is then sent to other multiplex control units. When ignition switch is turned off, there is a 10-second delay before sleep mode begins. Sleep mode will not begin if any door is open.
