Sender for rotation rate
-G202-
Implausible signal

Continuation:
Second: (Also note the fourth possibility)
The zero position of steering angle sensor -G85- is within the specified range, and the zero position
of the sensor for transverse acceleration -G200-, or the combined sensor for rotation rate and
transverse acceleration, is not within the specified range:


There is an open circuit in one of the signal
wires for the combined sensor for rotation
rate and transverse acceleration.
There is short circuit to B+ or Ground
(GND) in one of the signal wires for the
combined sensor for rotation rate and
transverse acceleration. Electrical Wiring Diagrams, Troubleshooting &
Component Locations - Check the signal wire for the combined sensor
for rotation rate and transverse acceleration,
terminal 4, to the ABS control module -J104-
(terminal 18).
