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.

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.
