During unlock operation, when the wireless door lock ECU receives an unlock signal from the door unlock detection switch, the wireless door lock buzzer goes on twice.
With any door open, when the wireless door lock ECU receives a lock signal from the transmitter, the wireless door lock buzzer goes on for approximately 10 seconds. If the door is closed, or if the unlock signal is received from the transmitter while the buzzer is on, the buzzer stops.
