POWER DOOR LOCK CONTROL SYSTEM SYSTEM DESCRIPTION


  1. POWER DOOR LOCK CONTROL SYSTEM DESCRIPTION


    1. The power door lock system locks/unlocks all the doors.

      The main 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 sends these request signals to the door lock motors in each door to lock/unlock each door in response to the inputs.

  3. SYSTEM FUNCTION


    1. This system is controlled by the main body ECU. The main 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.
      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.
      Double locking function*1

      • This function prevents the doors from being opened through the operation of the inside door knobs. Thus, the doors cannot be opened either from inside or outside the vehicle.

      • To lock the doors with this function, pressing the electrical key transmitter lock switch twice within 5 seconds or touching lock sensor on the outside door handle twice while holding the key within 5 seconds activates the double locking function. However, as an emergency unlocking maneuver, only the driver door can be unlocked with a key.

      Note

      Never activate the double locking function when there are people in the vehicle because the doors cannot be opened from the inside. If the doors are locked by accident, unlock the door by using the wireless unlock operation or entry unlock operation.
