Sound Quality Diagnosis
Diagnostics CD 07AAZ-SDBA100
Use the following tests to check sound quality.
NOTE: Before beginning the following tests, write down
the client’s bass, treble, fader and balance settings, and
then set them to their center positions for testing.
Do this test to confirm proper channel routing.
1. Insert the diagnostics CD (T/N: 07AAZ-SDBA100) into the navigation unit or audio unit.
2. Play track No. 1 (left, both, right channel ID) at a normal, or slightly higher than normal, volume
level.
3. The voice should be audible only from the channel or channels when indicated.
 If the channel ID is correct for each side, go to the phase test.
 If the channel ID is not correct, check for; – Shorted speaker wire
– Faulty amplifier (Type S model)
– Faulty navigation unit
– Faulty audio unit Diagnostics CD 07AAZ-SDBA100
Do this test to confirm proper speaker phasing.
1. Insert the diagnostics CD (T/N: 07AAZ-SDBA100) into the navigation unit or audio unit.
2. Play track No. 2 (phase) at a normal, or slightly higher than normal, volume level.
3. The voice should sound centered and focused when it is in-phase.
4. The voice should sound diffused, and have less bass when it is out of phase.
 If the voice changes from in-phase to out of phase as indicated by the prompt, the phasing is
correct. Go to electrical noise test.
 If the voice always sounds out of phase, phasing is not correct. Check for;
– Crossed speaker wires
– Faulty amplifier (Type S model)
– Faulty navigation unit
– Faulty audio unit

General Operation
Anti-theft Feature
Symptom DiagnosisSelf-Inertial Navigation Limitations
23-90Navigation System
General Troubleshooting Information
Refer to the Navigation System manual for the
navigation system operating procedures.
The navigation system has a coded theft protection
circuit. Be sure you have the client’s anti-theft security
code before;
 Disconnecting the battery
 Disconnecting the navigation unit A (17P) and C (12P) 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
(iN) to look it up. You can view the serial number in one
of the Navi ECU diagnostic screen (see page 23-139).
Alternatively, you can find the serial number from the
navigation unit in the dash.
When replacing the navigation unit, be sure to give the
client the new anti-theft security code.
Certain circumstances and system limitations can result
in occasional vehicle positioning errors. Some clients
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 clients
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 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.
