YAW RATE
This diagnostic checks the yaw rate sensor in the control unit. This device detects when the vehicle turns,
and repositions the vehicle position icon on the map screen. For more detailed information, see the yaw rate
sensor theory of operation under "System Description" (see YAW RATE-LATERAL ACCELERATION
SENSOR ).
"Sensor" indicates the voltage output from the yaw rate sensor. It should indicate about 2.500 volts

when stopped.
"Offset" is the reference voltage or standard within the yaw rate sensor. It also should indicate about

2.500 volts when stopped.
A "sensor" output voltage LOWER than the "Offset" voltage indicates that the vehicle is turning to

the right.
A "sensor" output voltage HIGHER than the "Offset" voltage indicates that the vehicle is turning to
the left.
The yaw rate offset, and sensor should both indicate about 2.500 volts when stopped. If either reads

zero, or 5.000 volts, replace the navigation unit.
The yaw rate offset and sensor should be within +/-0.01 V of each other when stopped. The sensor

value should change relative to the offset as the car is turned while driving. If not, replace the
navigation unit.
