General Information

Component Location





General Description

The yaw-rate sensor and later G sensor is installed on the lower floor.
The yaw-rate sensor detects acceleration of the vehicle around its vertical axis, while the G sensor detects lateral acceleration of the vehicle.
When the vehicle is not moving, the G sensor output is approximately 2.5V.

DTC Description

A lateral acceleration reference signal is calculated from the wheel speeds, the steering angle and the yaw rate signals to observe the lateral acceleration sensor signal.
The difference between the reference signal and the sensor signal is evaluated for failure detection.
A yaw rate reference signal is calculated from the wheel speeds, the steering angle and the lateral acceleration signals to observe the yaw rate sensor signal.
The difference between the reference signal and the sensor signal, and the gradient of the measured sensor signal is evaluated for the failure detection.
If the difference between estimated value and measured value of the sensor is larger than predefined value for predefined time, the failure is recognized. Also impossible signal according to sensor characteristic is detected the failure is recognized.
