Sleep and Wake-up Mode Test
1. Shift to the sleep mode:Turn the ignition switch to LOCK (0), and remove the key. If the MICU receives no signals from the inputs listed
below, it will go into sleep mode in less than 40 seconds.
Driver’s door lock switch (LOCK or UNLOCK)
Driver’s door key cylinder switch (LOCK or UNLOCK)
Front passenger’s door lock switch (LOCK or UNLOCK)
Trunk lid latch switch (Trunk lid closed)
Hazard warning switch (OFF)
2. Confirm the sleep mode: Measure the frequency on the B-CAN communication line (PNK wire); there should be 0 Hz when the system is in
the sleep mode. Check the parasitic draw at the battery while shifting into the sleep mode; the amperage should
change from about 200 mA to less than 35 mA.
3. Shift to the wake up mode: When the ignition switch is turned to ON (II), the MICU, gauge control module, immob ilizer-keyless control unit,
and ECM/PCM wake up at the same time without ‘‘talking’’ to each other through the communication lines. When
any switch in the multiplex integrated control system is turned on, it wakes up its related control unit which, in
turn, wakes up the other units. After confirming the sleep mode, look in the following table for the switch most
related to the problem. Operate that switch and see if its control unit wakes up.
NOTE: If any control unit is faulty and will not wake up, several circuits in the system will malfunction at the same
time. In the table below, the control unit is followed by a list of the switches and input signals that can wake it up.
Door switches (door open)
Driver’s door lock switch (LOCK or UNLOCK)
Driver’s door lock knob switch (LOCK or UNLOCK)
Driver’s door key cylinder switch (LOCK or UNLOCK)
Front passenger’s door lock switch (LOCK or UNLOCK)
Front passenger’s door lock knob switch (LOCK or UNLOCK)
Left rear door lock knob switch
Right rear door lock knob switch
Trunk lid latch switch (Trunk lid open)
Hood switch (with security) (hood open)
Hazard warning switch (ON)

General Troubleshooting Information (cont’d)
Navigation system is unable acquire a
 Move vehicle to another location
 Turn the ignition switch off
 Disconnect the battery for 30
minutes to clear the GPS receiver’s
memory
 Reconnect the battery and follow
the screen prompts proper GPS signal.
If the navigation system finds the satellites properly,
this box clears, and changes to the Disclaimer screen. If
within 10 minutes the system fails to locate a sufficient
number of satellites to locate your position, the
following screen appears.
After 30 minutes with this screen displayed, turn off the
engine, then restart the vehicle. If the Disclaimer screen
appears, the GPS initialization is complete.
NOTE:
 The average acquiring time is less than 10 minutes, but it can take as long as 45 minutes.
 If the system is still unable to acquire a signal, follow the instructions on the screen. If this screen appears
again, go to troubleshooting for the GPS icon is white
or not shown (see page 23-122).
 To bypass the GPS acquire screens, press and hold the Menu, and Zoom out keys at the same time.
Touch the Return button on the screen to exit the
diagnostic mode. This allows you to continue
troubleshooting while in the shop.
This part of the initialization matches the GPS
coordinates with a road on the map screen. To do this
part of the procedure, make sure that the navigation
system displays a map, and drive the vehicle on a
mapped road shown on the map screen. Do not enter a
destination at this time. When the name of the current
road you are driving on, appears at the bottom of the
screen, the entire procedure is complete. Your system
is now ready to use. If the navigation DVD is lost or damaged, or you need a
yearly
updated DVD, you have 2 ways to purchase one.
You can either call 888-291-4675, or order on-line at
www.hondanavi.com.
Both methods require a credit card. The DVD cannot be
ordered through the parts system. The following DVDs
will not work in this navigation system:
 Earlier model navigation DVDs (black, orange, or older vesions with a white label)
 Map software programs manufactured by other companies
 DVD movies, or DVDs containing audio recordings
 Copies of an original Navigation DVD
Update DVDs are available for purchase usually in the
fall of each year. They may contain the following:  Enhanced maps and points of interest (POI) coverage
 Fixes for minor software bugs
 Additional features
NOTE:  Map matching must be done any time the DVD is removed or replaced.
 Always order navigation DVDs on an as-needed basis. During a typical model year, each color DVD may
undergo a half a dozen software only version
upgrades to fix minor issues on some or all models
the DVD supports. This is normal. Usually only the
letter at the end of the version number changes,
while the database (maps and POIs) remain
unchanged.
 Never promise your customers future free updates.
There are no free programs for updating the
navigation DVD. Update DVDs are generally available
for purchase each fall. The on-time DVD order site
provides information when an update for a particular
color DVD is available, damaged discs are not
warrantable.

Phone Will Not Automatically Connect the
HFL
Incoming Calls
23-366HandsFreeLink System
General Troubleshooting Information (cont’d)
Many reasons for a dropped call are not related to the
HFL system. Here are some causes for dropped calls:
 If the quantity of dropped calls is about the same when the client uses the HFL system versus the
handset, the issue is likely due to the cellular phone
or carrier.
 If the phone is equipped with a retractable antenna, it needs to be extended to maximize signal strength.
 If a client also notices that the calls tend to drop in the same areas, the HFL system may be operating
normally, but something about the area diminishes
cellular coverage to a point where the call drops.
 Hills or m ountains can block or interfere with cellular
signals.
 High-rise buildings, bridges, or other large structures may block or interfere with cellular signals.
 Placing the cell phone in a purse, in a metal briefcase, under the seat, in the glove box, or in the trunk can all
affect signal reception.
 There are coverage gaps in the cellular service. When driving, a call is typically passed from one tower to
another. If the client drives through an area where
there is a coverage gap between towers, the call
drops.
 Electrical storms, heavy rain, or overcast c onditions
interfere with signal strength.
 The cell phone battery’s state of change can affect signal reception. A low battery may reduce the
phone’s ability to boost the antenna’s power and
function properly, especially in low signal strength
areas. Some phone manufacturers trade off signal
transmission and reception strength for battery life.
As the battery weakens, the signal strength may also
weaken. Some cell phones may operate more
effectively than others in low signal strength areas,
especially with a partially charged battery, and
depending on whether or not the retractable antenna
is fully extended (if applicable). On these models,
make sure the antenna is always extended to
maximize signal strength and extend battery life. If a client complains that their cell phone is not
automatically connecting to the HFL system when they
enter the vehicle, do this:
1. Make sure the Bluetooth feature is turned on in the cell phone.
2. Make sure the cell phone is properly painted to the HFL system.
3. Do a soft reset to the cell phone.
4. Check if the phone has an Authorized Connection or Trusted option.
5. Check the battery and signal strength on the cell phone. Pairing a phone requires optimal signal
strength and a nearly full battery.
If a client complains that they cannot receive incoming
calls through the HFL system, see if the call is routing to
the cell phone instead of the HFL system. An easy way
to know if the call is routed to the cell phone is when the
client says, ‘‘I can’t hear the caller, but they can hear me.’’ 1. Make sure the Bluetooth feature is turned on in the cell phone.
2. Make sure the cell phone is paired to the HFL system and linked.
3. Make sure the answer settings in the cell phone are set to multi-key or any-key answer. If the phone is
set to flip open to answer, recommend changing
the setting to Any Key or leaving the phone flipped
open when using the HFL system.
4. Make sure the Auto Answer feature is turned off in the cell phone.
5. Do a soft reset to the phone.
6. Make sure the battery is fully charged and there is adequate signal strength.
7. Ask the client if they have set specific ring tones or ringer IDs to specific contacts. If they have,
recommend using one standard ring tone for all
calls.
8. Make sure the client is pressing the HFL TALK button and not the HFL BACK button or the
navigation buttons.
