DESCRIPTION
The smart key system uses the wireless door lock buzzer to perform various vehicle exterior warnings. When the conditions for each warning are met, the certification ECU (smart key ECU assembly) sends a buzzer request signal to the main body ECU (driver side junction block assembly) via CAN communication. The wireless door lock assembly sounds the buzzer according to the signal from the main body ECU.
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.
