Removal and InstallationECS00FT2
COMPONENTS
CAUTION:
If transaxle assembly is removed from the vehicle, always replace CSC (Concentric slave cylin-
der). Return CSC insert to original position to remove transaxle assembly. Dust on clutch disc
sliding parts may damage CSC seal and may cause clutch fluid leakage.
Be careful not to apply any grease to the clutch disc facing, pressure plate surface and flywheel
surface.
REMOVAL
1. Remove transaxle assembly from the vehicle. Refer to MT-15, "Removal and Installation" .
2. Loosen clutch cover bolts evenly. Then remove clutch cover and clutch disc.
INSPECTION AND ADJUSTMENT AFTER REMOVAL
Clutch Disc
Check clutch disc for backlash of spline and runout of facing.
Check clutch disc for burns, discoloration or oil or grease leak-
age. Replace if necessary.
Measure backlash to clutch disc spline and input shaft spline at
the circumference of clutch disc. If outside the specification,
replace clutch disc.
1. Flywheel 2. Clutch disc *1, *2 3. Clutch cover
Apply lithium-based grease including molybdenum disulphide.
*1. Do not clean in solvent. *2. When installing, be careful that grease applied to input shaft does not adhere to
clutch disc.

Maximum backlash of spline
(at outer edge of disc): 1.0 mm (0.039 in)
Distance of runout check point
(from hub center): 215 mm (8.46 in)
Maximum allowable spline backlash : 1.0 mm (0.039 in)

CLUTCH DISC, CLUTCH COVER AND FLYWHEEL
Revision: June 20062007 Versa
Use a suitable tool to measure the depth to clutch disc facing
rivet heads. If it exceeds the allowable wear limit, replace clutch
disc.
Clutch Cover
Check clutch cover installed on vehicle for unevenness of diaphragm
spring toe height.
If out of limit, adjust the height using Tool (A).
Check clutch cover thrust ring for wear or breakage. If wear or
breakage is found, replace clutch cover assembly.
NOTE:
Worn thrust ring will generate a beating noise when tapped at
the rivet with a suitable tool.
Broken thrust ring will make a clinking sound when cover is shaken up and down.
If a trace of burn or discoloration is found on the clutch cover pressure plate to clutch disc contact surface,
repair the surface with sandpaper. If surface is damaged or distorted, replace the assembly.
Flywheel Runout
Check contact surface of flywheel for slight burns or discolora-
tion. Repair flywheel with emery paper.
Check the flywheel runout. Refer to EM-103, "FLYWHEEL
DEFLECTION (M/T MODELS)" .
CAUTION:
Measure flywheel outer face (not on knock pin and clutch cover
mounting hole).
INSTALLATION
1. Clean clutch disc and input shaft splines to remove grease and dust caused by abrasion.
2. Apply recommended grease to clutch disc and input shaft splines.
CAUTION:
Be sure to apply grease to the points specified. Otherwise, noise, poor disengagement, or damage
to the clutch may result. Excessive grease may cause slip or shudder. If it adheres to CSC seal, it
will cause clutch fluid leakage. Wipe off excess grease.
3. Install clutch disc using tool.
4. Install clutch cover. Pre-tighten clutch cover bolts.Wear limit of facing
surface to rivet head: 0.3 mm (0.012 in)

PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EBS00U8A
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.
WAR NIN G:
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 Necessary for Steering Wheel Rotation After Battery DisconnectEBS00U8C
NOTE:
This Procedure is applied only to models with Intelligent Key system and NATS (NISSAN ANTI-THEFT
SYSTEM).
Remove and install all control units after disconnecting both battery cables with the ignition knob in the
″LOCK″ position.
Always use CONSULT-II to perform self-diagnosis as a part of each function inspection after finishing
work. If DTC is detected, perform trouble diagnosis according to self-diagnostic results.
For models equipped with the Intelligent Key system and NATS, an electrically controlled steering lock mech-
anism is adopted on the key cylinder.
For this reason, if the battery is disconnected or if the battery is discharged, the steering wheel will lock and
steering wheel rotation will become impossible.
If steering wheel rotation is required when battery power is interrupted, follow the procedure below before
starting the repair operation.
OPERATION PROCEDURE
1. Connect both battery cables.
NOTE:
Supply power using jumper cables if battery is discharged.
2. Use the Intelligent Key or mechanical key to turn the ignition switch to the ″ACC″ position. At this time, the
steering lock will be released.
3. Disconnect both battery cables. The steering lock will remain released and the steering wheel can be
rotated.
4. Perform the necessary repair operation.
5. When the repair work is completed, return the ignition switch to the ″LOCK″ position before connecting
the battery cables. (At this time, the steering lock mechanism will engage.)
6. Perform a self-diagnosis check of all control units using CONSULT-II.

Multiport Fuel Injection (MFI) SystemUBS00PJS
INPUT/OUTPUT SIGNAL CHART
*1: This sensor is not used to control the engine system under normal conditions.
*2: This signal is sent to the ECM through CAN communication line.
*3: ECM determines the start signal status by the signals of engine speed and battery voltage.
SYSTEM DESCRIPTION
The amount of fuel injected from the fuel injector is determined by the ECM. The ECM controls the length of
time the valve remains open (injection pulse duration). The amount of fuel injected is a program value in the
ECM memory. The program value is preset by engine operating conditions. These conditions are determined
by input signals (for engine speed and intake air) from the crankshaft position sensor (POS), camshaft position
sensor (PHASE) and the mass air flow sensor.
VARIOUS FUEL INJECTION INCREASE/DECREASE COMPENSATION
In addition, the amount of fuel injected is compensated to improve engine performance under various operat-
ing conditions as listed below.
During warm-up
When starting the engine
During acceleration
Hot-engine operation
When selector lever is changed from N to D (A/T and CVT models)
