Navigation System

System Diagnosis Mode (cont'd)

Black Raster

The entire display must be shown in black.

Test Pattern

The chart below; shows the colors being used for the

map and menu screens. This is for factory use only. To

check the color signal use the "RGB Color" diagnostic

found under the Monitor Check menu item.

Monitor Adjustment

This allows the navigation display to be centered. Use

the joystick to move the picture up/down or left/right. It

is unlikely that you will ever need to adjust the monitor

position. The "Default" button will reset the display

position to factory specifications.
Touch Panel

The panel touch sensing system consists of 9 horizontal

and 20 vertical infrared beams. Touching the screen

blocks both a horizontal and a vertical beam. Every pos-

sible touch position is shown on this diagnostic screen.

Touching one of these areas should cause its color to

reverse, and sound a "beep". If any areas of the screen

either don't respond, or respond at some other location

when touched, then replace the display unit. The

"Display" diagnostic listed in Unit Check provides an

additional method to determine if one of the infrared

sources or detectors is bad.

NOTE: Direct sunlight can affect this test by falsely trig-

gering the infrared detectors, so perform this diagnostic

inside or in a shaded area.ProCarManuals.com

Unit Check

Touch the item you want to check and the check starts.
Display

This diagnostic performs additional checks on the com-

munication bus between the control unit and the dis-

play. In addition, the internal electronics and touch

screen functionality are confirmed.

• When the connection is NG, first check for loose ter-

minals at the navigation unit and the display unit

connections. Next check for an open or short in the

communication line between the navigation unit and

the display unit. If the line is found to have an open

or short, replace the affected shielded harness.

• If the ROM or RAM is NG, replace the display unit.

• If the touch sensor is NG, then check for zeros in the

"X", or "Y" values below.

• The version represents the software version in the

display.

• The "1" following the X, indicate the 20 working ver-

tical infrared beams/receptors (from left to right).

The "Is" following the Y, indicate the 9 working hori-

zontal beams (from top to bottom). If any one of the

"1s" is a zero, this indicates that these is a problem

with one of the beams or receptors. Check all around

the inside rim of the navigation screen for dirt or any-

thing that may be blocking a beam. If nothing is

found, replace the display unit. See the display unit

diagram in the "System Description" showing the

infrared beam layout. Individual touch positions can

be verified by running the "Touch Panel" diagnostic

under the Monitor Check menu choice.

NOTE: When selecting this diagnostic from "Unit

Check," quickly remove your fingers from the touch-

screen to avoid a false detection of the infrared sen-

Car Status

This screen is used to confirm that navigation unit is

properly receiving input signals. Signals equal to (0) are

OFF, and signals equal to (1) are ON.If the value on the

display does not match the actual vehicle status, then

check the wire carrying the signal.

• CHG and CHG(CAN) are not used for this model.

• VSP-Vehicle Speed Pulse from PCM

(Pin 6 of C-connector)

a) OFF (0) when vehicle is not moving

b) ON (1) when vehicle is moving

The VSP comes from the PCM as a dedicated signal.

Internally, the navigation unit compares the actual VP on

the map against street data to adjust the pulse to speed

scaling factor. As this scaling factor becomes more

accurate, the "Level" gradually increases from 0 to 10

(see the Tire Calibrate diagnostic screen).

• BACK-Reverse indication from reverse relay

(Pin 5 of C-connector)

a) OFF (0) when shift lever is in any position other

than reverse

b) ON (1) when shift lever is in reverse

The Back signal is used by the navigation unit to allow

the map screen to show the VP moving backwards when

in reverse. This signal is needed because the Speed

Pulse has no direction indication.
• ILL-lllumination Indication

(Pin 5 of navigation unit A-connector)

a) OFF (0) when parking lights, or headlights are off

b) ON (1) when parking lights, or headlights are on

This signal is used by the navigation unit to determine

whether to put the navigation screen into the Day or

Night brightness mode. (Setup screen 1)

• DVD Lid-senses if DVD door is open

a) (Close) when door is closed

b) (Open) when door is open

The navigation unit has a micro switch to detect this. If

open is indicated when the door is closed, replace the

navigation unit.

• PC Card Lid-Senses if PC Card door is open

a) (Close) when door is closed

b) (Open) when door is open

The navigation unit has a micro switch to detect this. If

open is indicated when the door is slid shut, then

replace the navigation unit. This slot is for insertion of

PC Flash memory cards for gathering diagnostic infor-

mation. This is for factory use only.ProCarManuals.com

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
