CIRCUIT
The navigation system is composed of the navigation unit, the ECM/PCM (vehicle speed signal), the GPS antenna,
microphone, voice control switch, XM receiver, and the climate control unit.
These units communicate with each other on the GA-Net bus.
The vehicle speed pulse is sent by the ECM/PCM. The ECM/PCM receives a signal from the output shaft (countershaft)
speed sensor, then it processes the signal and transmits it to the speedometer and other systems.

Glossary
Item Definition
23-287
The following is a glossary of terms pertaining to the Voice Recognition Navigation System.Active noise cancellation
(ANC) The active noise cancellation system cancels some of the vehicle noise. This occurs in the 1,500 2,400 rpm
range. Microphones detect the low frequency sound, and the system outputs a canceling sound from the
audio speaker.
Address Book The HFL system can import a copy of the phone book from and approved HFL compatible phone and display the imported phone book on the navigation screen as the address book. See the Owner’s Manual for more
information.
B-CAN Body CAN Bus (see CAN)
Bread-crumbs (White dots) Off road tracking dots that can be followed on the map to retrace your route back to a mapped (digitized) road. This function can be turned on/off in Setup screen 1.
CAN Controller Area Network. This communication network allows processors in the vehicle to send/receive information. The fuel pulses used by the MID trip computer are received from the ECM/PCM using the F-CAN
(Fast Controller Area Network) bus.
CPU Central Processing Unit. The main device within the navigation unit that coordinates the rest of the electronic functions.
CSS Countershaft (Output) Speed Sensor. This sensor reads the output shaft speed at the transmission and provides a speed pulse to the ECM/PCM.
Database This consists of the Map data, and the POI (Points Of Interest) data stored on the DVD.
DBW Drive By Wire. Allows electrical control of the throttle without the need of a mechanical linkage.
DCA Detailed Coverage Area. Main metropolitan areas in the Lower 48 states, and Canada are mapped to this level. See the navigation system manual for a list of these areas.
DTC Diagnostic Trouble Codes. Use the HDS tablet to obtain, and troubleshoot the cause of these codes.
Dead reckoning The use of the speed signal, and yaw rate sensor to position the vehicle on the map even when tall buildings, or driving in a tunnel obscures the GPS signal.
Digitized road A road that appears on the navigation screen. The road name appears at the bottom of the navigation screen. If the user drives off road, the navigation system displays not on a digitized road, and after 1/2 mile, the
bread-crumbs appear.
Disclaimer screen Screen containing cautionary information. It is meant to be read carefully, and acknowledged by the customer when using the navigation system.
DVD or DVD-ROM Digital Versatile Disk. The navigation program and database resides on this disk. See the Navigation Owner’s Manual for information on how to order a replacement or an update DVD.
ECM Engine Control Module. Typically referred to as the ECM.
FAQ Frequently Asked Questions. See the navigation system manual for a list of the customer FAQs, and troubleshooting information.
F-CAN Fast CAN Bus (see CAN)
GA-NET The GA-NET allows the audio unit to communicate with all the audio and navigation components in a vehicle. If there is an open in the GA-NET, components or the entire audio and navigation system may
appear inoperative.
GPS Global Positioning System. A network of 24 satellites in orbit around the earth. The navigation system can simultaneously receive signals from up to 12 satellites to accurately position the vehicle on the map.
HDS Honda Diagnostic System. A hand held tablet PC used for diagnosing vehicle problems. This device can be used to obtain DTC codes for diagnosis of the navigation system and CAN related problems.
HFL HandsFreeLink uses Bluetooth technology as a wireless link between it and an approved Bluetooth compatible cell phone. See Vehicle Owner’s manual or Quick Start Guide for more information.
HIP (AcuraLink) Honda Information Platform (see AcuraLink)
H/U Head Unit. The audio unit in the dash.
Initialization This refers to the period needed to re-acquire the GPS satellite orbital information whenever the navigation system power has been disconnected. This can take from 10 to 45 minutes.
Interface Dial This control device consists of a rotating knob and the buttons surrounding it. This device allows control of the navigation, audio, and climate functions displayed on the screen.
Jog Dial See interface dial.

Start the vehicle, and at the disclaimer screen use the
navigation display hard buttons as described below:
Make sure the battery is in good condition, then press
and hold the three buttons MAP/GUIDE, MENU, and
CANCEL, for about 3 seconds. The display screen goes
directly to the Select Diagnosis Items menu shown
below.
 Self-Diagnosis Mode (runs the automatic diagnosis of the navigation system)
 Detail Information & Setting (allows you to manually diagnose the navigation system) 1. By selecting Self-Diagnosis Mode from the
navigation screen main menu. The message at the
bottom of the screen flashes indicating the
diagnostic is running. Make sure you enter the
audio anti-theft code.
NOTE: The system cannot complete a full diagnosis unless the engine is running.
 DTC 2703 can be stored when the ignition switch is at ACCESSORY (I). With the ignition switch is
in ACCESSORY (I), the climate control unit is
turned off and the navigation unit loses
communication and stores DTCs. Therefore,
there is a possibility that the system is normal
even DTC 2703 is stored. Check system links with
the engine running, and if it shows normal, the
system is OK at this time.
2. Select the icon you want to diagnose. Push in the select the icon to see the details of that diagnostic
function.

This diagnostic screen checks the status of each of the
hard buttons surrounding the navigation display. When
you press each hard button, the corresponding item on
the screen should flash blue. Touch the return key, or
press and hold the joystick to exit.
NOTE: It is normal for the VOL ( , ) CH ( , ) and

This screen gives a quick test of the yaw sensor
functionality based on the two voltages Sensor and
Offset. For more information see the Yaw Rate
Diagnostic. This diagnostic tests the navigation DVD reader.
This diagnostic tests the climate bus connection (AC-SI
and AC-SO) between the navigation unit and climate
control unit. Make sure the engine is running for this
test.
 This checks the 4 wire communication bus between the HFL and the navigation.
 When connection is shown with NG, check the connection between the navigation unit and the
HandsFreeLink control unit.
