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.ProCarManuals.com

Navigation System

System Diagnosis Mode (cont'd)

Tire Calibrate

As the vehicle moves, the navigation system receives

speed pulses from the PCM. These pulses are converted

using a conversion factor to a mph speed that moves

the vehicle position (VP) on the map. The navigation

system has an internal tuning function that generates

and refines this factor based on actual driving. The

"Level" indicates the status of the tuning. At initializa-

tion, it begins at 0, and increases to 10 as the navigation

system is used.

• The "Auto Tuning" is factory set to "ON", and should

remain on.

• The "LEVEL" indicates the tuning status. If it is less

than 10, the unit is still calibrating.

• The "Tire-Cal. Tuning" and the "Set" button should

not be used. It is for factory use only.
Functional Setup

Touch the item you want to check.ProCarManuals.com

Log Data

This screen allows factory to collect log data to trou-

bleshoot navigation system issues.

• Normally there is no card in the "PC Card slot", and

the PC slot door should always be closed. The screen

should look like below.

• However, if the factory instructs you to insert a PC

Card, insert it into the card slot (label side up), and

then slide the PC Card door shut. If instructed by the

factory, touch the "Gyro. Sensor Logs ON" button on

the screen. Follow the factory procedure for gather-

ing test data, and properly ending the test.ProCarManuals.com

Navigation System

System Diagnosis Mode (cont'd)

GPS Offset Time

This screen is for factory use only. It allows adjustment

of the GPS time. This display updates in real time.

• "GPS Time" is the time as received from the GPS

satellites. It is in Greenwich Mean Time (GMT).

• "System Time" is the internal time used by the navi-

gation unit to calculate your position on the map.

It is also in Greenwich Mean Time (GMT).

• "Display Time" is the time shown on Setup screen 2

"Adjust Time Zone/Clock", and reflects any changes

due to daylight savings time or time adjustments

entered by the customer.

• Date, Hour, Minute, and "Set" buttons should not be

used.
Mic Level

This diagnostic allows you to independently test the

microphone and the TALK and BACK buttons on the

steering wheel (voice control switch). The microphone

and voice control switch are used to activate the voice

control system. The microphone is located near the map

light in the ceiling. It is directional, and works best if the

voice is coming from the drivers seat.

• Press the TALK button on the steering wheel, and in a

normal voice say "testing". The TALK indicator on

the screen should momentarily become green, and

the text "Now Recording..." should appear in yellow.

In addition, the Mic Level indicator should move at

least to the 6th bar. If the Talk indicator on the screen

does not briefly become green, then check the wiring

from the steering wheel talk button to the navigation

unit. If there is no "Mic Level" movement when you

speak, then you should check the wire running from

the microphone to the control unit.

• Press the BACK button on the steering wheel. This

should cause the Cancel indicator on the screen to

momentarily become green. If it does not briefly

change to green, then check the wiring from the

steering wheel BACK button to the navigation unit.ProCarManuals.com

VSP Count

This screen displays the number of pulses per revolu-

tion of the tire. This is for factory use only, and should

not be changed.

• "Pulse Count Setting" should always be set to

"Auto"

• "VSP Count" should always be "4", and should never

be adjusted or set to any other value.
Demonstration

This screen is for factory use only, and should always be

set to "OFF". Occasionally this setting is turned "ON"

when vehicles are being used at Auto Shows or similar

events. Turning this feature on, allows the navigation

system to automatically follow a route to a destination

when the vehicle is stationary.

Version

This screen displays the current version of the program,

and allows the loading of a new version of the program

either from a CD/DVD or from a PC card.

The D-Ram Program version should always be greater

than or equal to the Disc Program version. The mapped

database version is the date of the database on the DVD.

The Model code is 23H, and is for factory use only.

Do not use either of the load buttons, unless instructed

to do so by the factory.ProCarManuals.com
