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.

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

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
