PRECAUTIONS
PFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
ACS003KX
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. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Man-
ual.
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 TCM and CVT Assembly Replacement
ACS001SA
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.)
●
When replacing CVT assembly or TCM, refer to the pattern table below and erase the EEPROM in the
TCM if necessary.
EEPROM ERASING PATTERNS
METHOD FOR ERASING THE EEPROM IN THE TCM
1.
Connect CONSULT-II to data link connector.
2.
Turn ignition switch “ON”. Confirm that CONSULT-II is turned “ON”.
3.
Move selector lever to “R” position.
4.
Touch “START” on CONSULT-II.
5.
Select “SELF-DIAG RESULTS” mode for “TRANSMISSION” with CONSULT-II.
6.
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 TRANSMISSION
In the following procedure, the TCM reads data from the ROM assembly and writes it to the EEPROM in the
TCM.
1.
With the EEPROM in the TCM erased.
2.
Move selector lever to “P” position.
3.
Turn ignition switch “ON”.
CHECK METHOD
●
Normal: About 2 seconds after the ignition is switched to “ON” position, the CVT indicator lamp lights up
for 2 seconds.
●
Non-standard: Even after the ignition is switched to “ON” position, the CVT indicator lamp does not light
up after 2 seconds or illuminates immediately.
CAUTION:
Perform in the P or N position.
Cope for non-standard
●
Replace the CVT assembly.
●
Replace the TCM.
Removal and Installation Procedure for CVT Unit Connector
ACS003L1
REMOVAL
●
Rotate bayonet ring counterclockwise, pull out CVT unit harness
connector upward and remove it.
INSTALLATION
1.
Align
∆
marking on CVT unit harness connector terminal body
with
❏
marking on bayonet ring, insert CVT unit harness con-
nector, and then rotate bayonet ring clockwise.
2.
Rotate bayonet ring clockwise until
∆
marking on CVT unit har-
ness connector terminal body is aligned with the slit on bayonet
ring as shown in the figure (correctly fitting condition), install
CVT unit harness connector to CVT unit harness connector ter-
minal body.

PRECAUTIONS
Revision; 2004 April
2003 Murano
CAUTION:
●
Securely align
∆
marking on CVT unit harness connector
terminal body with bayonet ring slit. Then, be careful not
to make a half fit condition as shown in the figure.
●
Do not mistake the slit of bayonet ring for other dent por-
tion.
Precautions
ACS001SB
NOTE:
If any malfunctions occur in the RE0F09A model transaxle, replace the entire transaxle assembly.
●
Before connecting or disconnecting the TCM harness con-
nector, turn ignition switch “OFF” and disconnect negative
battery cable. Because battery voltage is applied to TCM
even if ignition switch is turned “OFF”.
●
When connecting or disconnecting pin connectors into or
from TCM, take care not to damage pin terminals (bend or
break).
When connecting pin connectors make sure that there are
not any bends or breaks on TCM pin terminal.
●
Before replacing TCM, perform TCM input/output signal
inspection and make sure whether TCM functions properly
or not.

●
After performing each TROUBLE DIAGNOSIS, perform
“DTC (Diagnostic Trouble Code) CONFIRMATION PROCE-
DURE”.
If the repair is completed the DTC should not be displayed in
the “DTC CONFIRMATION PROCEDURE”.
●
Always use the specified brand of CVT fluid. Refer to
MA-11, "Fluids and Lubricants"
●
Use paper rags, not cloth rags, during work.
●
After replacing the CVT fluid, dispose of the waste oil using the methods prescribed by law, ordinance,
etc.
Service Notice or Precautions
ACS001SC
OBD-II SELF-DIAGNOSIS
●
CVT self-diagnosis is performed by the TCM in combination with the ECM. The results can be read
through the blinking pattern of the CVT indicator or the malfunction indicator lamp (MIL). Refer to the table
on
CVT-71, "Self-Diagnostic Result Test Mode"
for the indicator used to display each self-diagnostic
result.
●
The self-diagnostic results indicated by the MIL are automatically stored in both the ECM and TCM mem-
ories.
Always perform the procedure on
to complete the repair and
avoid unnecessary blinking of the MIL.
For details of OBD-II, refer to
EC-68, "ON BOARD DIAGNOSTIC (OBD) SYSTEM"
.
●
Certain systems and components, especially those related to OBD, may use the new style slide-
locking type harness connector. For description and how to disconnect, refer to
Wiring Diagrams and Trouble Diagnosis
ACS001SD
When you read wiring diagrams, refer to the following:
●
GI-14, "How to Read Wiring Diagrams"
●
PG-3, "POWER SUPPLY ROUTING CIRCUIT"
for power distribution circuit.
When you perform trouble diagnosis, refer to the following:
●
GI-10, "How to Follow Trouble Diagnoses"
.
●
GI-26, "How to Perform Efficient Diagnosis for an Electrical Incident"
.

Checking CVT Fluid
ACS002KW
FLUID LEVEL CHECK
Fluid level should be checked with the fluid warmed up to 50 to 80
°
C (122 to 176
°
F). The fluid level check pro-
cedure is as follows:
1.
Check for fluid leakage.
2.
With the engine warmed up, drive the vehicle in an urban area.
When ambient temperature is 20
°
C (68
°
F), it takes about 10
minutes for the CVT fluid to warm up to 50 - 80
°
C (122 - 176
°
F).
3.
Park the vehicle on a level surface.
4.
Apply parking brake firmly.
5.
With engine at idle, while depressing brake pedal, move shift
selector throughout the entire shift range.
6.
Pull out the dipstick from the CVT fluid charging pipe after press-
ing the tab on the dipstick to release the lock.
7.
Wipe fluid off the dipstick and rotate the dipstick attached for
180
°
to securely insert the dipstick until it meets the end of the
CVT fluid charging pipe.
CAUTION:
Always use paper towels to wipe fluid off the dipstick.
8.
Place the selector lever in P or N and make sure the fluid level is
within the specified range.
CAUTION:
●
When CVT fluid level gauge reinstall, insert CVT fluid
charging pipe until CVT fluid level gauge is locking
surely.

FLUID CONDITION CHECK
Changing CVT Fluid
ACS002KX
1.
Warm up CVT fluid by driving the vehicle for 10 minutes.
2.
Drain CVT fluid from CVT fluid cooler hose (return side) and refill with new CVT fluid at CVT fluid charging
pipe with the engine running at idle speed.
3.
Refill until new CVT fluid comes out from CVT fluid cooler hose (return side).
About 30 to 50% extra fluid will be required for this procedure.
CAUTION:
●
Use genuine NISSAN CVT fluid NS-2.
●
Delete CVT fluid deterioration date with CONSULT-II after changing CVT fluid. Refer to
"Check CVT Fluid Deterioration Date"
4.
Check fluid level and condition.

Replace the CVT fluid and check
the CVT main unit and the vehicle
for malfunctions (wire harnesses,
cooler pipes, etc.)
Milky white or

Water in the fluid
Replace the CVT fluid and check for
places where water is getting in.
Large amount of
