Toyota Tacoma (2015-2018) Service Manual: Entry Interior Alarm does not Sound
DESCRIPTION
The smart key system (for Entry Function) uses the buzzer in the combination meter assembly 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
NOTICE:
- The smart key system (for Entry Function) uses a multiplex communication
system (LIN communication system) and the CAN communication system. Inspect
the communication function by following How to Proceed with Troubleshooting.
Troubleshoot the smart key system (for Entry Function) after confirming
that the communication systems are functioning properly (See page
