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.
Sensor indicates the voltage output from the yaw rate sensor. It should indicate about 2.500 V when stopped.
Offset is the reference voltage or standard within the yaw rate sensor. It also should indicate about 2.500 V 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 V when stopped. If either reads zero, or 5.000 V, 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.
Example: Vehicle stopped
Normal Abnormal
Offset 2.526 V Offset
Sensor 2.516-2.536 V Sensor
Example: Vehicle turning
Normal
Offset 2.526 V
Sensor 2.678 V (left turn)
2.478 V (right turn)
Sensitivity study represents the status of the internal tuning function. At initialization, this value starts at 6 and increases to 10 as the internal correction values become
more accurate.
The settings CCW Cal Factor, CW Cal Factor, and Set are for factory use only. THIS SHOULD NEVER BE ADJUSTED.
For detailed analysis of the yaw rate select tuning.
