DESCRIPTION
The smart key system uses the combination meter buzzer to perform various vehicle interior warnings. When the conditions for each warning are met, the certification ECU (smart key ECU assembly) sends a buzzer signal to the combination meter assembly, and the combination meter buzzer sounds.
