Yaw rate sender -G202
Implausible signal
|
The input signals received by control unit -J104 are processed by internal programs and tested for plausibility. In the case of yaw rate sender -G202, the program mainly relies on the steering angle sender -G85 and the lateral acceleration sender -G200. If the yaw rate sender -G202 is suspected of being the cause of the problem a check must be made to ensure that the steering angle sender -G85 and the lateral acceleration sender -G200 are functioning properly. They must also be checked.
With vehicle moving in a straight line (v < 20 km/h) check zero position of steering angle sender -G85 by selecting function 08 "Read measured value block", => Page 01-249, display group 5.
