Glass breakage sensor ECU circuit
CIRCUIT DESCRIPTION
The glass breakage sensor microphone detects the sound of metal (and other) objects striking the windows
and outputs a signal to the glass breakage sensor ECU. Sound of breaking window glass is amplified (fixed
frequency) by the resonator provided in front of the microphone.
The glass breakage sensor ECU receives a signal from the glass breakage sensor microphone. If the signal
matches the specification, the ECU outputs the glass breakage signal to the body ECU.
The body ECU receives the signal from the glass breakage sensor ECU and outputs a warning.
