ENTRY AND START SYSTEM (for Entry Function) Entry Answer-back Buzzer does not Sound

DESCRIPTION

The entry and start system uses the wireless door lock buzzer assembly to perform various vehicle exterior warnings. When the conditions for each warning are met, the certification ECU (smart key ECU assembly) sends a buzzer request signal to the main body ECU (multiplex network body ECU) via CAN communication. The wireless door lock assembly sounds the buzzer according to the signal from the main body ECU (multiplex network body ECU).
