Buzzer Circuit
CIRCUIT DESCRIPTIONWhen there is no answer back in spite of the fact that the wireless door lock and unlock function is operating, there might be an abnormality in the outputs of the hazard light signal from the theft warning ECU and also in the outputs of the wireless buzzer.
NOTE:
- The wireless door lock system has a function with large-scale multiplex communications. First of all, inspect the communication function depending on the "How To Proceed With Troubleshooting", and check that there is no abnormality in the communication system. Then finally proceed with the troubleshooting.
- The troubleshooting should be started after the confirmation that the hazard answer back function is customized and the buzzer controller switch is not in the OFF position.
