C1282 Yaw Rate & Lateral G Sensor-Electrical - General Information

Component Location





General Description

The ESC system is the shorten word of Electronic Stability Program system. This system recognizes a critical driving condition by Yaw-rate sensor, Lateral acceleration sensor and Steering angle sensor. And then it stabilizes the vehicle by a individual wheel braking and engine torque control through CAN communication. Among components of this system, the yaw-rate & lateral G sensor is installed on the lower of the center console. The yaw-rate and the lateral G sensor are installed together in the one container which is called as "Cluster". When the vehicle is moving around a vertical axis, the yaw rate sensor senses the vibration changes of the plate-fork installed in the yaw-rate sensor. When the vehicle's yawing is sensed and the yaw velocity reaches a certain velocity, the ESC control is activated. The lateral G sensor senses a vehicle's lateral acceleration. A small element in the sensor is attached to a deflectable lever-arm. The HECU recognizes a vehicle's direction and a lateral acceleration by the lateral G sensor.

DTC Description

The HECU monitors the signals of the yaw-rate and the lateral G sensor and if its signals are detected out of the normal range, this DTC is set.
