No Answer-Back: Description

In some cases, wireless door lock control functions are normal but the hazard warning lights and/or wireless door lock buzzer answer-back function(s) do not operate. In such cases, the main body ECU hazard warning lights and/or wireless door lock buzzer signal outputs may be malfunctioning.

NOTE: Troubleshooting should be started after confirming that the answer-back function has been set to ON.
