C1283 Yaw Rate & Lateral G Sensor-Signal - General Information

Component Location





General Description

When the vehicle is turning, the yaw rate sensor detects the yaw rate electronically by the vibration change of plate fork inside the yaw rate sensor. If the yaw velocity reaches the specific velocity after it detects the vehicle's yawing, the ESC control is reactivated. The lateral G sensor senses the vehicle's lateral acceleration. A small element inside the sensor is attached to a deflectable leverarm by lateral acceleration. Direction and magnitude of lateral acceleration loaded to vehicle can be known by electrostatic capacity changing according to lateral acceleration. It interchanges signals with HECU through extra CAN line which is only used for communication between HECU and the sensor. In case of the vehicle with 4WD & ESC, G sensor is packaged with yaw rate & later G sensor.

DTC Description

If the difference between the estimated value from the other sensors and the measured value from the yaw rate and lateral G sensor is larger than predefined value for predefined time, the failure is recognized.
