Wake-Up Function Test

Description:
^ When the ignition switch is turned ON (II):
When the ignition switch is ON (II), all of the multiplex control units wake up at the same time. In this case, the communication lines are not related for wake up function.
^ When a switch related to the multiplex control unit (door) is operated:
First, the multiplex control unit (door) wakes up, then the control unit starts to communicate to the control unit (driver's). By this communication, the control unit (driver's) wakes up. The control unit (driver's) wakes the control unit (passenger's) up by the communication line, and all the control units start to function.
^ When a switch related to the multiplex control unit (driver's or passenger's) is operated:
The control unit related to the operated switch wakes up, then the control unit wakes up the other unit. (In this case, the control unit (door) does not wake up.)
