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)

CAUTION:
Be careful not to damage the mating surfaces.

Tap Tool to insert it (1), and then slide it by tapping on the side
(2) as shown.

In areas where Tool is difficult to use, use plastic hammer to
lightly tap the parts, to remove it.
CAUTION:
If for some unavoidable reason suitable tool such as screw-
driver is used, be careful not to damage the mating sur-
faces.
LIQUID GASKET APPLICATION PROCEDURE
1. Remove old liquid gasket adhering to the liquid gasket applica-
tion surface and the mating surface, using scraper.

Remove liquid gasket completely from the groove of the liquid
gasket application surface, bolts, and bolt holes.
2. Thoroughly clean the mating surfaces and remove adhering
moisture, grease and foreign materials.
3. Attach liquid gasket tube to Tool.
Use Genuine RTV Silicone Sealant or equivalent. Refer to GI-46, "
Recommended Chemical Prod-
ucts and Sealants" .
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 liquid gasket to the groove.

As for the bolt holes, normally apply liquid gasket inside the
holes. Occasionally, it should be applied outside the holes.
Make sure to read the text of service manual.

Within five minutes of liquid gasket application, install the mat-
ing component.

If liquid gasket protrudes, wipe it off immediately.

Do not retighten nuts or bolts after the installation.

After 30 minutes or more have passed from the installation, fill
engine oil and engine coolant.
CAUTION:
If there are specific instructions in this manual, observe them.Tool number : KV10111100 (J-37228)

Revision: June 20062007 Versa
Precautions for On Board Diagnostic (OBD) System of CVT and EngineUCS005XG
The ECM has an on board diagnostic system. It will light up the malfunction indicator lamp (MIL) to warn the
driver of a malfunction causing emission deterioration.
CAUTION:

Be sure to turn the ignition switch OFF and disconnect the battery cable from the negative termi-
nal before any repair or inspection work. The open/short circuit of related switches, sensors, sole-
noid valves, etc. will cause the MIL to light up.

Be sure to connect and lock the connectors securely after work. A loose (unlocked) connector will
cause the MIL to light up due to an open circuit. (Be sure the connector is free from water, grease,
dirt, bent terminals, etc.)

Be sure to route and secure the harnesses properly after work. Interference of the harness with a
bracket, etc. may cause the MIL to light up due to a short circuit.

Be sure to connect rubber tubes properly after work. A misconnected or disconnected rubber tube
may cause the MIL to light up due to a malfunction of the EVAP system or fuel injection system,
etc.

Be sure to erase the unnecessary malfunction information (repairs completed) from the TCM and
ECM before returning the vehicle to the customer.
Service After Replacing TCM and Transaxle Assembly UCS006L3
SERVICE AFTER REPLACING TCM AND TRANSAXLE ASSEMBLY
Perform the applicable service in the following sheet when replacing TCM or transaxle assembly
CAUTION:

Do not start the engine until the service is completed.

“A/T C/U POWER SUPPLY [P1701]” may be indicated soon after replacing TCM or transaxle
assembly (after erasing the memory at the pattern B). Restart the self-diagnosis after erasing the
self-diagnosis result. Check that no error is detected.
NOTE:
Old unit means that the unit has been already used for another vehicle.
PATTERN A
1. Shift the selector lever to “P” position after replacing TCM. Turn the ignition switch ON.
2. Check that the shift position indicator in the combination meter turns ON (It indicates approximately 1 or 2
seconds after turning the ignition switch ON.)

Check the following items if the shift position indicator does not turn ON. Repair or replace the shift
position indicator if necessary.
–The harness between TCM and ROM ASSY in the transaxle assembly is open or short.
–Cable disconnected, loosen, or bent from the connector housing.
PATTERN B
1. Turn the ignition switch ON after replacing each part.
2. Connect CONSULT-II connector to data link connector. Refer to GI-38, "
CONSULT-II Start Procedure" .
3. Start engine.
CAUTION:
Do not start the driving.
4. Touch CONSULT-II screen in the order of “START (NISSAN BASED VHCL)”, “TRANSMISSION”, “DATA
MONITOR”, and “MAIN SIGNALS”.
5. Warm up the transaxle assembly until “ATF TEMP” indicates 48 (approximately 20°C) or more. Turn the
ignition switch OFF.

DESCRIPTION
The MIL is located on the instrument panel.
1. The MIL will light up when the ignition switch is turned ON with-
out the engine running. This is a bulb check.

If the MIL does not light up, refer to DI-24, "WAR NIN G
LAMPS" , or see EC-592, "MIL AND DATA LINK CONNEC-
TOR" .
2. When the engine is started, the MIL should go off.
If the MIL remains on, the on board diagnostic system has
detected an engine system malfunction.
