G Sensor

The G sensor installed to the floor beside the parking brake lever detects the vehicle deceleration speed.
It is a distortion gauge type semi-conductor sensor consisting of a detector and an amplifier circuit. As the vehicle speed changes, distortion occurs and the resistance of the distortion gauge varies according to that distortion. This resistance is converted into voltage in the bridge circuit and in this way, deceleration speed of the vehicle body is detected. (ABS control module detects whether the vehicle stops or moves).
