WIRELESS DOOR LOCK CONTROL SYSTEM(w/o Entry and Start System) SYSTEM DESCRIPTION


  1. WIRELESS DOOR LOCK CONTROL SYSTEM DESCRIPTION


    1. This system locks and unlocks the vehicle doors remotely. The wireless control system has the following features:


      • The door control receiver performs the code identification procedure and the main body ECU operates the door lock control. A serial data link is provided for communication between the receiver and main body ECU.

      • A key-integrated type transmitter is used and it contains the following 3 switches: the door lock switch, door unlock switch and luggage switch.

  2. FUNCTION OF MAIN COMPONENTS

    Component Function
    Door control transmitter

    • Contains lock, unlock and luggage switches.


    • Transmits weak electric waves (recognition codes and function codes) to door control receiver.
    Door control receiver Receives weak electric waves (recognition codes and function codes) from door control transmitter, and changes waves to code data.
    Door lock (door unlock detection switch) Transmits door lock conditions of each door to main body ECU.
    Unlock warning switch Detects if key is in ignition key cylinder.
