Parts Function
Front door outer handle ASSY LH/RH Upon reception of a request signal transmitted from the collation ECM (smart key ECM ASSY) via the electrical key antenna, the front door outer handle ASSY LH/RH creates a detection area outside the vehicle. When replacing the collation ECM (smart key ECM ASSY), it is also necessary to replace all the electrical key transmitter SUB-ASSYs. The front door outer handle ASSY LH/RH transmits a door lock sensor operation signal to the collation ECM (smart key ECM ASSY) (entry lock function).
The front door outer handle ASSY LH/RH detects the operation performed on itself via the touch sensor, and transmits a signal to the collation ECM (smart key ECM ASSY) (entry unlock function).
Indoor electrical key antenna ASSY no. 1 (front floor), indoor electrical key antenna ASSY no. 2 (rear floor) Receive request signals from the collation ECM (smart key ECM ASSY), and form the vehicle interior detection area.
Indoor electrical key antenna ASSY No. 3 (trunk) Upon reception of a request signal transmitted from the collation ECM (smart key ECM ASSY), the indoor electrical key antenna ASSY no. 3 (trunk) creates a detection area inside the trunk.
Electrical key antenna (trunk exterior) Upon reception of a request signal transmitted from the collation ECM (smart key ECM ASSY), the electrical key antenna (trunk exterior) creates a detection area outside the trunk.
Trunk opening switch ASSY The trunk door opening switch ASSY transmits a switch operation signal to the collation ECM (smart key ECM ASSY).
Door control receiver The door control receiver receives an entry & start system code/wireless code transmitted from the electrical key transmitter SUB ASSY and then transmits it to the collation ECM (smart key ECM ASSY).
Wireless door lock buzzer This warning buzzer is activated by the collation ECM (smart key ECM ASSY).
Electrical key transmitter SUB-ASSY Sends the ID code when it receives a request signal.
Collation ECM (smart key ECM ASSY) The collation ECM (smart key ECM ASSY) transmits a request code to each electrical key antenna. It identifies and checks the ID code transmitted from the electrical key transmitter SUB ASSY and then transmits a signal to an appropriate ECM according to the function operated.
When an ignition operation is performed, the collation ECM (smart key ECM ASSY) exchanges encrypted codes with the steering lock ECM (steering lock actuator ASSY).(1)
When an ignition operation is performed, the collation ECM (smart key ECM ASSY) exchanges encrypted codes with the ID code box (immobilizer code ECM).(2)
(1) Without ID code box

(2) With ID code box
