GENERAL TROUBLESHOOTING INFORMATION

GENERAL OPERATION

Refer to the Navigation System manual, for the navigation system operating
procedures.

ANTI-THEFT FEATURE

The navigation system has a coded theft protection circuit. Be sure you have the
customer's anti-theft security code before;

Disconnecting the battery

Disconnecting the navigation unit 12P and 17P connector

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
ON (II). Enter the 4-digit anti-theft security codes, then select Done.

If the code cannot be found, use the interactive Network (i N) to look it up. You can
view the serial number in one of the Navi ECU diagnostic screen (see TOUCH
PANEL CALIBRATION). Alternatively, you will need the serial number from the
navigation unit in the dash.

When replacing the navigation unit, be sure to give the customer the new anti-theft
security code.

SYMPTOM DIAGNOSIS

Certain circumstances and system limitations will result in occasional vehicle
positioning errors. Some customers 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 customers about symptoms of the navigation system.

SELF-INERTIAL NAVIGATION LIMITATIONS

The limitations of the self-inertial portion of the navigation system (the yaw rate
sensor and the vehicle speed signal) can cause some discrepancies between the
vehicle's actual position and the indicated vehicle 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.

Tolerances in the system and map inaccuracies will sometimes limit how
precisely the vehicle 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 direction to destination icon or the destination icon shown or the map
may be up to several hundred feet away from the actual location.

GLOBAL POSITIONING SYSTEM (GPS) LIMITATIONS

The GPS cannot detect the vehicle's position during the following conditions:

Metallic window tinting above the GPS antenna,

When only three satellite signals can be received (Four satellite signals are
required for accurate positioning).

When driving near high tension power lines.

When the satellite signals are blocked by the operation of some electronic after
market 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.

When the satellite control centers are experiencing problems.

The accuracy of GPS is reduced during these instances:

Metallic window tinting above the GPS antenna.
