ZDX V6-3.7L (2010)
Wake-Up and Sleep Function
The multiplex integrated control system has wake-up and sleep functions to decrease parasitic draw on the battery when the ignition switch is turned to
LOCK (0), or the vehicle ignition is in the OFF mode.
-
In the sleep mode, the multiplex integrated control system stops functioning (communication and CPU control) whenever it is not necessary for the
system to operate.
-
As soon as any operation is requested (for example, a door is unlocked), the related control units in the sleep mode immediately wake up and begin
to function.
-
When the ignition switch is turned to LOCK (0), or the engine start/stop button is pressed to select the OFF mode, and the driver's door is opened,
then closed, there is a delay of about 40 seconds before the control unit goes from the wake-up mode to the sleep mode.
-
The sleep mode will not function if any door is open or if a key is in the ignition switch.
-
When in sleep mode, parasitic draw is reduced from 200 mA to less than 35 mA.
