Circuit Operation

The front impact sensor (RH) transmits acceleration data to the SRS-ECU. The SRS-ECU then determines whether to operate the front air bags, and then outputs an ignition signal when necessary. The front impact sensor also diagnoses itself, and sends a diagnostic trouble code to the SRS-ECU if a malfunction occurs.
