Yaw Rate
This diagnostic checks the yaw rate sensor in the control
unit. This device detects when the vehicle turns, and
repositions the vehicle posion 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 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 HIGHER than the "Offset"
voltage indicates that the vehicle is turning to the
right.
A "sensor" output voltage LOWER 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.
• Auto tuning should always be on. If it is off, turn it
on.
• "Sensitivity study" represents the status of the inter-
nal tuning function. At initialization, this status of the
internal tuning function. At initialization, this value
starts at 6 and increases to # 10 as the internal correc-
tion values become more accurate.
• The settings "CCW Cal Factor", "CW Cal Factor", and
"Set" are for factory use only. THIS SHOULD NEVER
BE USED.
