A gravity sensor (G-sensor) circuit system including a microcontroller that determines whether there is a failure in the G-sensor and, if it is determined that there is a failure in the G-sensor, outputs a failure signal to a controller outside the PCB, or the controller outside the PCB communicates with the G-sensor to determine whether there is a failure in the G-sensor, thus performing the self-diagnosis. The gravity sensor (G-sensor) circuit system performs self-diagnosis, zero-offset, and digital output, thereby using a more accurate sensor signal, improving the vehicle stability, and increasing the control precision and accuracy.
