ABS/ESC - C1283 Yaw Rate & Lateral G Sensor-Signal - General Information
Component Location
General Description
The yaw-rate sensor and lateral G sensor is installed on the lower floor. When the vehicle is turning around its vertical axis, the yaw rate sensor detects the yaw rate electronically by the vibration change of plate fork inside the yaw rate sensor. If yaw velocity reaches the specific velocity, , the ESC control is activated. The lateral G sensor senses vehicle's lateral G value. Direction and magnitude of lateral G loaded to vehicle can be known with electrostatic capacity changing according to lateral G value. It interchanges signals with HECU through extra CAN line which only used for communication between HECU and sensor.
DTC Description
The HECU monitors the signals of the yaw-rate and the lateral G sensor and if the abnormal signal is detected or the difference between the acceleration value calculated from the changes of wheel speed and the the acceleration value measured from the sensor is above a certain value, this DTC is set.
