Entry Exterior Alarm and Answer-back Buzzer do not Sound [10/2018 - 07/2022]: Description

The smart access system with push-button start (for Entry Function) uses the wireless door lock buzzer to perform various vehicle exterior warnings. When the conditions of each warning are met, the certification ECU (smart key ECU assembly) sends a buzzer activation request signal to the main body ECU (multiplex network body ECU) via CAN communication and the buzzer sounds.
