This malfunction affects the voltage supply
of the control module.
This DTC is only stored, if it occurs the first
time the vehicle exceeds 6 km/h.
As soon as the supply voltage is again
within the valid voltage range, the system
is switched back on and the warning lights
turn off.
Open circuit or resistance too high
between voltage supply of terminal 15
and ABS control module -J104-

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
