Yaw Rate Tuning
This diagnosis 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 diagnosis). When the sensor functions normally, 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 select CCW, CW, or Set. These are used for factory setup only.
There are two available tests for diagnosing the yaw rate sensor. For persistent problems with the sensor, the stationary test usually confirms whether or not the sensor is defective. For yaw sensor issues that occur only when driving, perform the road test diagnostic.
1. Stationary test: If the VP icon spins with the vehicle parked and the vehicle is the READY TO DRIVE mode and the ANG-Disp value slowly increases or decreases, the yaw rate sensor is defective. Replace the audio-navigation unit - Refer to: Audio-Navigation Unit Removal and Installation (2014 2015), or Audio-Navigation Unit Removal and Installation (With Display Audio) (2017) .
2. Road test: Drive the vehicle on a very straight, smooth road. Enter the diagnostic mode, select Yaw rate, and select 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 audio-navigation unit's yaw sensor is defective. To run the test again, select Reset to clear ANG-Disp, and the dotted lines. If either test above fails, please enter Yaw rate sensor defective for the problem description, on the audio-navigation unit return form.
