Confirming Wake-Up Mode

When ignition switch is turned to ON position, all multiplex control units wake-up together without communicating with each other through communication lines. When any switch related to door multiplex control unit is activated, it will wake-up door multiplex control unit, which in turn will wake-up driver's multiplex control unit and it will then wake-up passenger's multiplex control unit. When a switch related to driver's or passenger's multiplex control unit is activated, it will wake-up its related multiplex control unit, but only the driver's and passenger's multiplex control units will wake-up. Door multiplex control unit will not wake-up. If checking a problem, turn on a switch in the following lists which is most closely related to suspected problem and see if it will wake-up related multiplex control unit. If any multiplex control unit is faulty and cannot wake-up, several parts of multiplex system will not operate. After confirming sleep mode, turn each of following switches to ON position and wake-up each multiplex control unit. If system operate properly, wake-up mode is okay.
