FRONT IMPACT SENSOR

The front impact sensors are installed on front end module, and contains an analogue G-sensors.
The front impact sensors transmit coded acceleration data to SRS-ECU. The SRS-ECU then determines
whether to operate the driver’s air bag, passenger’s (front) air bag and seat
belt pre-tensioners, and then outputs an ignition signal when necessary. The front impact sensor
also diagnoses itself, and sends a diagnosis code to the SRS-ECU if a problem occurs.
