System Description

POWER DOOR LOCK CONTROL SYSTEM DESCRIPTION
1. The power door lock system locks/unlocks all the doors.
  The driver and front passenger side door control switches send lock/unlock request signals to the main body ECU (multiplex network body ECU). Then, the main body ECU (multiplex network body ECU) sends these request signals to the door lock motors in each door to lock/unlock all the doors at once in response to the inputs.
  
  Operating the driver door lock using a mechanical key sends request signals to lock or unlock the doors to the main body ECU (multiplex network body ECU).

FUNCTION OF MAIN COMPONENTS

Component	Function
Multiplex network master switch assembly	Driver side door control switch on the master switch locks or unlocks all doors.
Door control switch (power window regulator switch assembly)	Front passenger side door control switch on the power window regulator switch assembly locks or unlocks all doors.
Door courtesy light switch assembly	Placed on each door. Detects door status (open or closed) and outputs data to main body ECU (multiplex network body ECU). Turns on when door is opened and turns off when door is closed.
Front door lock assembly LH	Built-in motor locks or unlocks door. Built-in door control switch (key-linked) detects door key operation status (locked or unlocked) and outputs a signal to main body ECU (multiplex network body ECU). Built-in position switch detects door status (locked or unlocked) and outputs a signal to main body ECU (multiplex network body ECU). This switch turns off when door is locked and turns on when door is unlocked.
Front door lock assembly RH Rear door lock assembly LH/RH	Built-in motor locks or unlocks door. Built-in position switch detects door status (locked or unlocked) and outputs a signal to main body ECU (multiplex network body ECU). This switch turns off when door is locked and turns on when door is unlocked.

SYSTEM FUNCTION

This system is controlled by the main body ECU (multiplex network body ECU). The main body ECU (multiplex network body ECU) outputs signals to each door lock motor. The power door lock control system has the following functions:

Function	Outline
Manual lock and unlock function	This function can lock or unlock all doors by the door control switch operation.
Key-linked lock and unlock function	This function, which is linked with the mechanical key cylinder, can lock or unlock all doors when a lock or unlock operation is effected.

Key lock-in prevention function	When the key is in the vehicle, performing the door lock operation will not lock the door.
Collision door lock release	If the SRS has been deployed and the main body ECU (multiplex network body ECU) has detected the signal that is output from the center airbag sensor assembly, the main body ECU (multiplex network body ECU) will unlock all doors.
2-step unlock function	Unlocks only the driver door by turning the key cylinder once and unlocks the other doors by turning it twice.
Shift-linked automatic door lock function*3	When the conditions listed below are met consecutively, this function causes all doors to be automatically locked. All doors are closed. The engine is started. The shift lever is moved out of P.
