Sender for
rotation rate -
G202-
Implausible
signal The input signals received by ABS control module -J104- are analyzed by computing programs and
checked for plausibility. If the sender for rotation rate -G202- fails, the relevant computing program relies
primarily on the steering angle sensor -G85- and the sensor for transverse acceleration -G200-. If you
think there is a problem with the sender for rotation rate -G202-, check whether the steering angle
sensor -G85- and sensor for transverse acceleration -G200- are OK. These must also be checked.
- While driving straight ahead (v < 20 km/h), check the zero position of the steering angle sensor -G85-,
by selecting display group 5 in "Read measuring value block", function 08 page 01
-256
.
- Check the sensor for transverse acceleration -G200- as described in the instructions for "Read
measuring value block" function 08 page 01
-270
