General Operation
Anti-theft Feature
Symptom Diagnosis
Self-Inertial Navigation LimitationsGlobal Positioning System (GPS) Limitations
23-266Navigation System
General Troubleshooting Information
Refer to the navigation system manual for the
navigation system operating procedures.
The navigation system and audio unit have a coded
theft protection circuit. Make sure you have the anti-
theft security code before:
Disconnecting the battery.
Disconnecting the navigation unit connector A (24P) and C (8P).
Removing the No. 23 (10 A) fuse from the under-hood fuse/relay box.
After service, reconnect power to the navigation unit,
and turn the ignition switch to ON (II). Enter the 4-digit
anti-theft security code, then select Done.
If the code cannot be found, use the interactive Network
(iN) to look it up. You can view the serial number in one
of the ECU Info diagnostic screens (see page 23-305).
Alternatively, you can find the serial number on the
underside label which is located on the navigation unit
in the trunk.
When replacing the navigation unit, be sure to give the
customer the new anti-theft security code.
Certain circumstances and system limitations will result
in occasional vehicle positioning errors. Some client’s
may think this indicates a problem with the navigation
system when, in fact, the system is normal. Keep the
following items in mind when interviewing client’s
about symptoms of the navigation system.
The limitations of the self-inertial portion of the
navigation system (the yaw rate sensor and the vehicle
speed signal) can cause discrepancies between the
vehicle’s actual position and the indicated vehicle’s
position (GPS vehicle position). The following circumstances may cause vehicle
positioning errors:
Moving the vehicle with the engine stopped and the vehicle stopped, such as by ferry or tow truck, or if
the vehicle is spun on a turn table.
Tire slippage, changes in tire rolling diameters, and some driving situations may cause discrepancies in
travel distances. Examples of this include:
– Continuous tire slippage on a slippery surface
– Driving with snow chains mounted
– Abnormal tire pressure
– Incorrect tire size
– Frequent lane changes across a wide highway
– Continuous driving on a straight or gently curving highway
– Very bumpy roads
Tolerances in the system and map inaccuracies sometimes limit how precisely the vehicle’s position
is indicated. Examples of this include:
– Driving on roads not shown on the map (map matching is not possible)
– Driving on a road that winds in one direction, such as a loop bridge, an interchange, or a spiral parking
garage
– Driving on a road with a series of sharp hair-pin turns
– Driving near a gradual highway exit or transition
– Driving on one of two close parallel roads
– Making many 90 degree turns
The GPS cannot detect the vehicle’s position or
elevation during the following instances: For the first 5 to 10 minutes after reconnecting the battery (this process can take as long as 45 minutes).
When the satellite signals are blocked by tall buildings, mountains, tunnels, large trees, inside
parking structures or large trucks.
When the GPS antenna is blocked by metallic window tinting or by an object placed above it in the
vehicle. The GPS antenna requires a clear
unobstructed view of the sky.
When there is no satellite signal output (signal output is sometimes stopped for sate llite servicing).
When the satellite signals are blocked by the operation of some electronic aftermarket accessories
including, but not limited to non-OEM in-dash
entertainment units (radio, CD players/changers,
radar detectors and theft recovery systems) and cell
phones placed near the navigation system.

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.
