    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 (multiplex network body ECU).
      Lock Position Switch Detects whether the doors are locked or unlocked and sends this information to the main body ECU (multiplex network body ECU).
      Door Control Receiver Receives the ID code from the transmitter and transmits it to the main body ECU (multiplex network body ECU).*1
      Receives the ID code from the key and transmits it to the certification ECU (smart key ECU assembly).*2
      Certification ECU (Smart Key ECU Assembly)*2

      • Judges the ID code from the door control receiver and sends the verification result to the main body ECU (multiplex network body ECU).

      • Receives the engine switch on (IG) status from the engine switch and transmits it to the main body ECU (multiplex network body ECU).
      Main Body ECU (Multiplex Network Body ECU) Turns on or off each light using signals from each switch and the certification ECU (smart key ECU assembly)*2.
