Answer Back Control
When using the remote, the MICU provides an answer back function to alert the client that the MICU received a lock or unlock command from the remote.
When the MICU receives a lock signal, the MICU sends signals once to the turn signal lights, and keyless buzzer will sound once when you press the Lock button again within 5 seconds.
When the MICU receives an unlock signal, the MICU sends signals two twice to the turn signal lights.
