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 (entry function) provides various indoor warnings by setting off a buzzer via the combination meter assembly. When the specific conditions for each waning are met, the collation ECM (smart key ECM assembly) sends a buzzer drive request signal to the combination meter assembly via the CAN communication to beep the buzzer.
