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

, display group 5, page 01
