Sender for rotation rate
-G202-, signal wire
Failure in electrical
circuit
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 6, to the ABS control module -J104-
(terminal 79).
