Entry Lock Function

a) This signal is transmitted to the certification ECU when the driver (who has the key in their possession), exits the vehicle and presses the lock switch on the outside door handle.

b) The certification ECU transmits a request signal for all door and room oscillators to form actuation areas.

c) The key receives this signal and returns the ID code to the tuner.

d) The certification ECU judges and certifies the ID code from the tuner. It then checks the location of the key and, if all the doors are closed, the ECU transmits a door lock signal to the main body ECU.

e) The main body ECU receives this signal and actuates the door lock motors to lock the doors.

f) The main body ECU blinks hazard warning lights once and the certification ECU sounds the wireless door lock buzzer once as an answerback for the entry lock function.
