LIGHTING SYSTEM


  1. FUNCTION OF MAIN COMPONENTS


    1. The main components in the illuminated entry system have the following functions:

      Component Function
      Door Courtesy Light Switch Assembly Detects whether the doors are open or closed and sends this information to the main body ECU.
      Lock Position Switch Detects whether the doors are locked or unlocked and sends this information to the main body ECU.
      Park/Neutral Position Switch Assembly*1 Detects the shift position and sends this information to the main body ECU via the ECM.
      Power Management Control ECU Sends power condition information to the main body ECU.
      Parking Brake Switch*2 Tells the main body ECU whether the parking brake is on or off.
      Door Control Receiver Receives the ID code from the transmitter and transmits it to the main body ECU.*3
      Receives the ID code from the key and transmits it to the certification ECU.*4
      Door Electrical Key Oscillator*4 Receives the request signals from the certification ECU, and creates an exterior actuation area around the door.
      Certification ECU*4 Judges the ID code from the door control receiver and sends the verification result to the main body ECU.
      Main Body ECU Turns on or off each light using signals from each switch and the ECU.
