TROUBLE DIAGNOSIS FOR SYMPTOMS

ABS Function Does Not OperateBFS000EN
CAUTION:
ABS does not operate when speed is 10 km/h (6 MPH) or lower.
1. CHECK ABS WARNING LAMP DISPLAY
Make sure that the warning lamp turns off approximately 2 second after the ignition switch is turned on or
when driving.
OK or NG
OK >> GO TO 3. Check Wheel Sensor and Sensor Rotor. Refer to BRC-82, "Excessive ABS Function
Operation Frequently" .
NG >> Perform self-diagnosis. Refer to BRC-58, "
Self-Diagnosis" .
Pedal Vibration and ABS Operation Sound OccursBFS000EO
CAUTION:
Under the following conditions, ABS is activated and vibration is felt when brake pedal is lightly
depressed (just place a foot on it). However, this is normal.

When shifting gears

When driving on slippery road

During cornering at high speed

When passing over bumps or grooves [at approximately 50 mm (1.97 in) or more]

When pulling away just after starting engine [at approximately 10 km/h (6 MPH) or more]
1. SYMPTOM CHECK 1
Check if there is pedal vibration and operation sound when the engine is started.
OK or NG
OK >> GO TO 2.
NG >> Perform self-diagnosis. Refer to BRC-58, "
Self-Diagnosis" .
2. SYMPTOM CHECK 2
Check symptoms when electrical component (headlamps, etc.) switches are operated.
Do symptoms occur?
YES >> Check if there is a radio, antenna, antenna lead wire, or wiring close to the control unit. If there is,
move it farther away.
NO >> GO TO 3. Check Wheel Sensor and Sensor Rotor. Refer to BRC-82, "
Excessive ABS Function
Operation Frequently" .

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
BBS0059V
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. Information necessary to service the system safely is included in the SRS and SB section of
this Service Manual.
WARNING:

To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be per-
formed by an authorized NISSAN/INFINITI dealer.

Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.

Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.
Precautions for Liquid GasketBBS005AV
REMOVAL OF LIQUID GASKET SEALING

After removing mounting nuts and bolts, separate the mating
surface using seal cutter (SST) and remove old liquid gasket
sealing.
CAUTION:
Be careful not to damage the mating surfaces.

Tap seal cutter to insert it, and then slide it by tapping on the
side as shown in the figure.

In areas where seal cutter (SST) is difficult to use, use plastic
hammer to lightly tap the parts, to remove it.
CAUTION:
If for some unavoidable reason tool such as screwdriver is
used, be careful not to damage the mating surfaces.
LIQUID GASKET APPLICATION PROCEDURE
1. Using scraper, remove old liquid gasket adhering to the liquid
gasket application surface and the mating surface.

Remove liquid gasket completely from the groove of the liquid
gasket application surface, mounting bolts, and bolt holes.
2. Wipe the liquid gasket application surface and the mating sur-
face with white gasoline (lighting and heating use) to remove
adhering moisture, grease and foreign materials.
3. Attach liquid gasket tube to tube presser (SST).
Use Genuine Liquid Gasket or equivalent.
4. Apply liquid gasket without breaks to the specified location with
the specified dimensions.

If there is a groove for the liquid gasket application, apply liq-
uid gasket to the groove.

Precautions for TCM and CVT Assembly ReplacementBCS001FR
When replacing CVT assembly or TCM, refer to the pattern table below and erase the EEPROM in the TCM if
necessary.
CAUTION:

Check if new data (Unit ID) are entered correctly after replacing CVT assembly and erasing data in
TCM. (Connect CONSULT-II, and then turn ignition switch OFF.)

“TCM POWER SUPPLY [P1701]” may be indicated soon after replacing TCM or transaxle assembly
(after erasing the memory). Restart the self-diagnosis after erasing the self-diagnosis result.
Check that no error is detected.
EEPROM ERASING PATTERNS
METHOD FOR ERASING THE EEPROM IN THE TCM
1. Connect CONSULT-II to data link connector. Refer to CVT-45, "CONSULT-II SETTING PROCEDURE" .
2. Turn ignition switch ON. Confirm that CONSULT-II is turned ON.
3. Move selector lever to “R” position.
4. Touch “START (NISSAN BASED VHCL)” on CONSULT-II.
5. Select “SELF-DIAG RESULTS” mode for “TRANSMISSION” with CONSULT-II.
6. Press the brake pedal and turn the brake switch ON.
7. Press the accelerator pedal (0.5/8 - 4/8 throttle) not to exceed the half, and hold it in the half or less open
position. (This will set the closed throttle position signal to OFF and the wide open throttle position signal
to OFF.)
8. Touch “ERASE” on CONSULT-II, and then touch “YES”.
9. Wait 3 seconds and then release the accelerator pedal.
10. Turn ignition switch OFF.
METHOD FOR WRITING DATA FROM THE ROM ASSEMBLY IN THE TRANSAXLE
In the following procedure, the TCM reads data from the ROM assembly and writes it to the EEPROM in the
TCM.
1. Erase the EEPROM in the TCM.
2. Move selector lever to “P” position.
3. Turn ignition switch ON.
CHECK METHOD

Standard: About 2 seconds after the ignition switch ON, the CVT indicator lamp lights up for 2 seconds.

Non-standard: Even after the ignition switch ON, the CVT indicator lamp does not light up after 2 seconds
or illuminates immediately.
CAUTION:
Perform in the “P” or “N” position.
Action for Non-standard

Replace the CVT assembly.

Replace the TCM.
CVT assembly TCM Erasing EEPROM in TCM Remarks
Replaced Replaced Not requiredNot required because the EEPROM in the TCM is in
the default state. (CVT assembly must be replaced
first.)
Not replaced Replaced Not requiredNot required because the EEPROM in the TCM is in
the default state.
Replaced Not replaced RequiredRequired because data has been written in the
EEPROM in the TCM and because the TCM cannot
write data from the ROM assembly in the transmis-
sion.

COMBINATION METERS

COMBINATION METERSPFP:24814
System DescriptionBKS001RX
UNIFIED METER CONTROL UNIT

Speedometer, odo/trip meter, tachometer and fuel gauge are controlled by the unified meter control unit,
which is built into the combination meter. Unified meter control unit receives signals from unified meter
and A/C amp.

Warning lamp and indicator lamp of combination meter are controlled by signals drawn from the unified
meter and A/C amp.

Digital meter is adopted for odo/trip meter*.
*The record of the odo meter is kept even if the battery cable is disconnected. The record of the trip meter
is erased when the battery cable is disconnected.

Odo/trip meter and shift indicator segments can be checked in diagnosis mode.

Meters/gauges can be checked in diagnosis mode.
Illumination control

Unified meter control unit produces an illumination output of the
combination meter when the ignition switch is “ON”.

Light levels can be adjusted by pressing illumination control
switch of the combination meter when lighting switch is “ON”.

Illumination control switch has five light level settings.
NOTE:
When it is light outside, light level cannot be adjusted by turning
on the lighting switch.

UNIFIED METER AND A/C AMPPFP:27760
System DescriptionBKS001SK

For the unified meter and A/C amp., the signal required for con-
trolling the combination meter are integrated in the A/C auto
amp.

Unified meter and A/C amp. controls each operation for A/C
auto amp. For information regarding A/C control, refer to AT C -
24, "AIR CONDITIONER CONTROL" .

Unified meter and A/C amp. inputs necessary information for
combination meter from each unit by CAN communication and
so on.

And unified meter and A/C amp. outputs these signals using
communication line (TX, RX) between unified meter and A/C
amp. and combination meter.

The signals required for the distance to empty (DTE) display are centralized in the unified meter and A/C
amp., converted into data, and sent to the display unit (with display unit) using CAN communication.

Other input signals are also sent to the ECM, TCM, BCM and display unit (with display unit) using CAN
communication.

The unified meter and A/C amp. correspond a CONSULT-II function (self-diagnostic results, CAN diag-
nostic support monitor and data monitor).
