"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."

YAW RATE TUNING
This diagnostic allows you to graphically display problems with the yaw rate sensor.
The "ANG-Disp" value accumulates any differences between the "offset," and "sensor" voltages (see

Yaw Rate diagnostic, refer to YAW RATE) . When the sensor is working properly, the random
changes in these two voltages generally cancels out, so the value is 0. However if one voltage is
consistently higher than the other, then the "ANG-Disp" value accumulates the constant change.
The "Reset" button temporarily clears the angular accumulation (ANG-Disp), and clears the display

dots.
Do not touch the "CCW," "CW," or "Set" buttons. These are used for factory setup only.

Two tests are explained below. For gross problems with the sensor, the stationary test usually confirms
whether the sensor is defective. For yaw rate issues related to driving, perform the road test described below.
1. Stationary test: If the "VP" icon spins in place and the "ANG-Disp" value slowly increases or
decreases in value, the yaw rate sensor is defective. Replace the navigation control unit.
2. Road test: Drive the vehicle on a very straight road. Enter the diagnostic mode, select "Yaw rate," and
touch the "Tuning" button. While driving down a straight road, the white "dots" should trace a straight
line across the screen. However, if you are driving on a straight road, and you notice the dots
constantly dropping down or heading up as you drive, the navigation control unit's yaw sensor is
defective. You can touch "Reset" to clear "ANG-Disp," and dotted lines.
If either test above fails, please enter "Yaw rate sensor defective" for the problem description, on the
"Navigation core return form."
