PUSH-BUTTON START Entry Interior Alarm does not Sound

DESCRIPTION

The push-button start uses the buzzer in the combination meter assembly (meter ECU) to perform various vehicle interior warnings. When the conditions of each warning are met, the certification ECU (smart key ECU assembly) sends a buzzer activation request signal to the combination meter assembly via CAN communication and the buzzer sounds.

CAUTION / NOTICE / HINT

Note


  • The push-button start uses the LIN communication system and CAN communication system. Inspect the communication function by following How to Proceed with Troubleshooting. Troubleshoot the push-button start after confirming that the communication systems are functioning properly.
