Glass Breakage Sensor ECU Circuit

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.
