Diagnosis by Error History

When having a difficulty on the investigation of cause due to multiple errors with a reproducible malfunc-
tion, turn ON the ignition switch from OFF mode after making a memo of the item and number of time (or
delete “Error History”). Check “Error History” again after the malfunction was reproduced, and then per-
form diagnosis focusing on the item of which number of time increased.

DVD-ROM error history may be restored because DVD-ROM cannot be temporarily read. (Driving on
rough road etc.) Then, erase the error history. (This is not a malfunction.) Perform service in “Action to
take” if error history are repeatedly indicated again.
Error item Possible cause Action to take
GPS Antenna Error GPS antenna connection malfunction
is detected. 1. Start self-diagnosis, and make sure of
the result.
2. If any error is found, GO TO 3. If any error is not found, delete the error his-
tory and end the diagnosis. (This is not
a malfunction.)
3. Check if GPS antenna feeder line is snapped or pinched.
4. If the results from the above checkup show no malfunction, replace GPS
antenna, and then restart self-diagno-
sis.
5. If self-diagnosis results still show any malfunction, replace NAVI control unit.
FLASH-ROM Error Of Control Unit
NAVI control unit malfunction is
detected. 1. Start self-diagnosis, and make sure of
the result.
2. If any error is found, replace NAVI con- trol unit. Refer to AV-155, "
Removal
and Installation of NAVI Control Unit" .
If any error is not found, delete the error
history and end the diagnosis. (This is
not a malfunction.)
Connection Of Gyro
GPS Communication Error GPS malfunction is detected. If the symptoms such as the GPS receipt
malfunction occur, intermittent malfunc-
tion caused by strong radio interference
may be detected.
If the malfunction always occurs, replace
NAVI control unit.
GPS ROM Error
GPS RAM Error
GPS RTC Error
DVD-ROM Mechanism not Detected

Malfunction is detected on DVD-
ROM drive pickup lens in NAVI con-
trol unit.

There is dirt and damage on the
DVD-ROM. 1. Check if the inserted DVD-ROM is
specified for this navigation system,
and the DVD-ROM is dirty, scratched or
warped.
2. If the results from the above checkup show no malfunction, insert the same
DVD-ROM, and then restart self-diag-
nosis.
3. If self-diagnosis results still show any malfunction, replace NAVI control unit.

PRECAUTIONS
Revision: 2006 December 2006 FX35/FX45

If there is a radio, antenna, or antenna lead-in wire (including wiring) near control module, VDC/TCS/ABS
function may have a malfunction or error.

If aftermarket parts (car stereo, CD player, etc.) have been installed, check for incidents such as harness
pinches, open circuits, and improper wiring.

If the following components are replaced with non-genuine components or converted, VDC OFF indicator
lamp and SLIP indicator lamp may turn on or the VDC system may not operate properly. Components
related to suspension (shock absorber, strut, spring, bushing, etc.), Tires, wheels (exclude specified size),
components related to brake (pad, rotor, caliper, etc.), components related to engine (muffler, ECM, etc.),
components related to body reinforcement (roll bar, tower bar, etc.).

Driving in the condition of breakage or excessive wear of suspension, tires or components related to the
brakes may cause VDC OFF indicator lamp and SLIP indicator lamp turn on, and the VDC system may
not operate properly.

When the TCS or VDC is activated by sudden acceleration or sudden turn, some noise may occur. The
noise is a result of the normal operation of the TCS and VDC.

When driving on roads which have extreme slopes (such as mountainous roads) or high banks (such as
sharp carves on a freeway), the VDC may not operate normally, or VDC OFF indicator lamp and SLIP
indicator lamp may turn on. However, this is not a malfunction, if normal operation can be resumed after
restarting engine.

Sudden turns (such as spin turns, acceleration turns), drifting, etc. When VDC function is OFF (VDC OFF
SW ON) may cause the G sensor system indicate a malfunction. However, this is not a malfunction, if nor-
mal operation can be resumed after restarting engine.

Change 4 tires at a time. Be sure to use specified-size tires that have the same brand name and pattern.
Wheel sensor errors can be detected be self-diagnosis when tires have wide abrasion variations or the
size is different from the genuine tires.

TROUBLE DIAGNOSIS FOR SYMPTOMS
Revision: 2006 December 2006 FX35/FX45
The Braking Distance is LongNFS000O0
CAUTION:
On slippery road surfaces, the stopping distance might be longer with the ABS operating than when
the ABS is not operating.
1. CHECK FUNCTION
Disconnect ABS actuator and electric unit (control unit) connector E56 to deactivate ABS. In this condition,
check stopping distance. After inspection, connect connector.
OK or NG
OK >>
Bleed air from brake piping.

Check brake system.
NG >> GO TO 2. CHECK WHEEL SENSOR. Refer to BRC-51, "
Excessive ABS Function Operation Fre-
quency" .
The ABS Function Does Not OperateNFS000O1
CAUTION:
The ABS does not operate when the speed is 10 km/h (6 MPH) or less.
1. CHECK ABS WARNING LAMP DISPLAY
Make sure warning lamp turns off approximately 2 seconds after the ignition switch is turned ON or when driv-
ing.
OK or NG
OK >> GO TO 2. CHECK WHEEL SENSOR. Refer to BRC-51, "Excessive ABS Function Operation Fre-
quency" .
NG >> Perform self-diagnosis. Refer to BRC-25, "
Self-Diagnosis" .
Pedal Vibration or ABS Operation Sound OccursNFS000O2
CAUTION:
Under the following conditions, when brake pedal is lightly depressed (just place a foot on it), ABS is
activated and vibration is felt. However, this is normal.

When shifting gears

When driving on slippery road

During cornering at high speed

When passing over bumps or grooves

When pulling away just after starting engine [at approximately 10 km/h (6 MPH) or higher]
1. SYMPTOM CHECK 1
Check if pedal vibration or operation sound occurs when engine is started.
OK or NG
OK >> Perform self-diagnosis. Refer to BRC-25, "Self-Diagnosis" .
NG >> GO TO 2.
2. SYMPTOM CHECK 2
Check symptom when electrical component (headlamps, etc.) switches are operated.
Does the symptom occur when the electrical component (head lamp, etc.) switches are operated?
YES >> Check if there is a radio, antenna, antenna lead wire, or wiring close to ABS actuator and electric unit (control unit) (or its wiring), and if there is, move it farther away.
NO >> GO TO 2. CHECK WHEEL SENSOR. Refer to BRC-51, "
Excessive ABS Function Operation Fre-
quency" .

PRECAUTIONS
Revision: 2006 December 2006 FX35/FX45

B1 indicates the bank 1, B2 indicates the bank 2 as shown
in the figure.

Do not operate fuel pump when there is no fuel in lines.

Tighten fuel hose clamps to the specified torque.

Do not depress accelerator pedal when starting.

Immediately after starting, do not rev up engine unneces-
sarily.

Do not rev up engine just prior to shutdown.

When installing C.B. ham radio or a mobile phone, be sure
to observe the following as it may adversely affect elec-
tronic control systems depending on installation location.
–Keep the antenna as far as possible from the electronic
control units.
–Keep the antenna feeder line more than 20 cm (8 in) away
from the harness of electronic controls.
Do not let them run parallel for a long distance.
–Adjust the antenna and feeder line so that the standing-
wave radio can be kept smaller.
–Be sure to ground the radio to vehicle body.
