PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001703112
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 performed by
an authorized NISSAN/INFINITI dealer.
• Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal
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 har-
ness connectors.
Precaution for Procedure without Cowl Top CoverINFOID:0000000001843684
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
Service Notice or PrecautionINFOID:0000000001703113
•Use recommended brake fluid when adding fluid to the clutch reservoir tank. Refer to MA-10.
•Never reuse fluid drained from clutch system.
•Be careful not to splash brake fluid on painted areas.
•Use new brake fluid to clean or wash all parts of master cylinder and operating cylinder.
•Never use mineral oils such as gasoline or kerosene. It will ruin the rubber parts of the hydraulic sys-
tem.
•If transaxle assembly is removed from the vehicle, always replace CSC (Concentric slave cylinder).
Return CSC to original position to remove transaxle assembly. Dust on clutch disc sliding parts may
damage CSC seal and may cause clutch fluid leakage.
•Do not disassemble clutch master cylinder and CSC.
WARNING:
After cleaning clutch disc, clean it with a dust collector. Do not use compressed air.

PRECAUTIONS
• Be sure to turn the ignition switch OFF and disconnect the battery cable from the negative terminal
before any repair or inspection work. The open/short circuit of related switches, sensors, solenoid
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 AssemblyINFOID:0000000001703427
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 assem-
bly (after erasing the memory at the pattern B). Restart the self-diagnosis after erasing the self-diag-
nosis 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 posi-
tion 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. Start engine.
CAUTION:
Do not start the driving.
3. Touch CONSULT-III screen in the order of “START (NISSAN BASED VHCL)”, “TRANSMISSION”, “DATA
MONITOR”, and “MAIN SIGNALS”.
4. Warm up the transaxle assembly until “ATFTEMPCOUNT” indicates 47 [approximately 20°C (68°F)] or
more. Turn the ignition switch OFF.
5. Turn the ignition switch ON.
CAUTION:
Do not start engine.
6. Select “SELF-DIAG RESULTS”.
7. Shift the selector lever to “R” position.

Removal and Installation Procedure for CVT Unit ConnectorINFOID:0000000001703428
REMOVAL
Rotate bayonet ring counterclockwise, pull out CVT unit harness
connector upward and disconnect it.
INSTALLATION
1. Align CVT unit harness connector terminal body marking with
bayonet ring marking, insert CVT unit harness connector, and
then rotate bayonet ring clockwise.

CVT-10
< SERVICE INFORMATION >
PRECAUTIONS
2. Rotate bayonet ring clockwise until CVT unit harness connector
terminal body marking is aligned with the bayonet ring marking
(linear slit) as shown.
CAUTION:
• Securely align CVT unit harness connector terminal body
marking with bayonet ring marking (linear slit). Do not
make a half fit condition as shown.
• Do not mistake the bayonet ring marking (linear slit) for
other dent portion.
PrecautionINFOID:0000000001703429
NOTE:
If any malfunction occurs in the RE0F08A model transaxle, replace the entire transaxle assembly.
•Before connecting or disconnecting the TCM harness connec-
tor, turn ignition switch OFF and disconnect negative battery
cable. Because battery voltage is applied to TCM even if igni-
tion 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.
