Circuit description

WARNING: This page is about a different car, the 2014 Subaru BRZ. However, it is still accessible from the selected car via links, so may be relevant.

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.
