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.
CAUTION / NOTICE / HINT
NOTICE:
The smart key system (for entry function) uses a multiplex communication system
(LIN communication system) and CAN communication system. Inspect the communication
function by following How to Proceed with Troubleshooting (See page
). Troubleshoot the smart key system (for entry
function) after confirming that the communication system is functioning properly.
