Circuit description

The entry & start system uses the wireless door lock buzzer to provide various exterior warnings. When the specific conditions for each waning are met, the collation ECM (smart key ECM assembly) transmits a buzzer signal to the main body ECM via the CAN communication. The main body ECM then transmits the signal to the wireless door lock buzzer to sound the buzzer.
