System Description

POWER DOOR LOCK CONTROL SYSTEM DESCRIPTION
1. The power door lock system locks/unlocks all the doors.
  The main body ECU (multiplex network body ECU) receives lock/unlock request signals from a door control switch or the driver door key lock and unlock switch. Then, the main body ECU (multiplex network body ECU) sends these request signals to the door lock motors in each door to lock/unlock each door in response to the inputs.

FUNCTION OF MAIN COMPONENTS

Front door lock assembly LH	Built-in motor locks or unlocks door. Built-in key lock and unlock 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 unlock detection 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 unlock detection 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.
Back door lock assembly	Built-in motor unlatches door latch. Performs back door open operation according to locked/unlocked state determination of main body ECU (multiplex network body ECU). Built-in courtesy switch Detects back door status (open or closed) and output data to main body ECU (multiplex network body ECU) turns on when back door is opened and turns off when back door is closed

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.
Manual unlock prohibition function	When the condition below is met, unlocking the vehicle using the door control switch will be prohibited: The doors are locked using a mechanical key, electrical key transmitter or entry lock operation with all doors closed.
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 airbag sensor assembly, the main body ECU (multiplex network body ECU) will unlock all doors.
Key-linked 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*1	When the conditions listed below are met consecutively, this function causes all doors to be automatically locked: All doors are closed. The hybrid control system is started. With park (P) selected, the shift lever is moved to select another shift state.
