REMOVAL AND INSTALLATION
Removal
1. Disconnect the battery negative terminal.
2. Remove engine under cover and fender protector (LH). Refer to EI-22, "
Removal and Installation" .
3. Drain the A/T fluid. Refer to AT-16, "
A/T FLUID" .
4. Remove oil pan and oil pan gasket.
5. Check for foreign materials in oil pan to help determine cause of
malfunction. If the ATF is very dark, smell burned or contains for-
eign particles, friction material (clutches, band) may need
replacement. A tacky film that will not wipe clean indicates var-
nish build up. Varnish can cause valves, servo, and clutches to
stick and can inhibit pump pressure.

If ATF contains frictional material (clutch, bands, etc.),
replace radiator and flush cooler line using cleaning sol-
vent and compressed air after repair of A/T. Refer to CO-
11, "RADIATOR" .
6. Remove magnets from oil pan.
1. A/T 2. O-ring 3. Return spring

Keyfob Battery and Function CheckEIS0091I
1. CHECK KEYFOB BATTERY
1. Remove keyfob battery. Refer to BL-78, "
Keyfob Battery Replacement" .
2. Measure voltage between battery positive and negative termi-
nals, (+) and (−).
NOTE:
Keyfob does not function if battery is not set correctly.
OK or NG
OK >> GO TO 2.
NG >> Replace battery.
2. CHECK KEYFOB FUNCTION
With CONSULT-II
Check keyfob function in “DATA MONITOR” mode with CONSULT-II. When pushing each button of keyfob, the
corresponding monitor item should be turned as follows.
Without CONSULT-II
Check keyfob function using Remote Keyless Entry Tester J-43241.
OK or NG
OK >> Keyfob is OK.
NG >> Replace keyfob.Voltage : 2.5 – 3.0V

BL-78
REMOTE KEYLESS ENTRY SYSTEM
Revision: June 20062007 Versa
NOTE:

If a keyfob is lost, the ID code of the lost keyfob must be erased to prevent unauthorized use. A specific ID
code can be erased with CONSULT-II. However, when the ID code of a lost keyfob is not known, all con-
troller ID codes should be erased. After all ID codes are erased, the ID codes of all remaining and/or new
keyfobs must be re-registered.
To erase all ID codes in memory, register one ID code (keyfob) five times. After all ID codes are erased,
the ID codes of all remaining and/or new keyfobs must be re-registered.

When registering an additional keyfob, the existing ID codes in memory may or may not be erased. If five
ID codes are stored in memory, when an additional code is registered, only the oldest code is erased. If
less than five ID codes are stored in memory, when an additional ID code is registered, the new ID code is
added and no ID codes are erased.

If you need to activate more than two additional new keyfobs, repeat the procedure “Additional ID code
entry” for each new keyfob.

Entry of maximum five ID codes is allowed. When more than five ID codes are entered, the oldest ID code
will be erased.

Even if same ID code that is already in the memory is input, the same ID code can be entered. The code
is counted as an additional code.

DISASSEMBLY AND ASSEMBLY OF INTELLIGENT KEY
1. Release the lock knob at the back of the Intelligent Key and remove the mechanical key.
2. Insert a flat-blade screwdriver (A) wrapped with a cloth into the
slit of the corner and twist it to separate the upper part from the
lower part.
CAUTION:

Be careful not to touch the circuit board or battery termi-
nal.

The key fob is water-resistant. However, if it does get wet,
immediately wipe it dry.
3. Replace the battery with new one.
4. Align the tips of the upper and lower parts, and then push them
together until it is securely closed.
CAUTION:

When replacing battery, be sure to keep dirt, grease, and
other foreign materials off the electrode contact area.

After replacing the battery, check to make sure all Intelli-
gent Key functions work normally.
INTELLIGENT KEY BATTERY INSPECTION
Check by connecting a resistance (approximately 300Ω) so that the
current value becomes about 10 mA.
Remote Keyless Entry FunctionEIS0 09 DF
Check keyfob function using Remote Keyless Entry Tester J-43241.

Trouble Diagnosis ProcedureEIS0093W
PRELIMINARY CHECK
1. GET SYMPTOMS
Listen to customer complaints request. (Get symptoms)
NOTE:
If customer reports a “No start” condition, request all Intelligent Keys to be brought to the dealer in case of
Intelligent Key system malfunction.
Intelligent Key or mechanical key service request>> For further information, refer to CONSULT-II operation
manual.
Malfunctions>>GO TO 2.
2. START ENGINE WITH INTELLIGENT KEY (IF EQUIPPED)
Check if the engine could be started by all registered Intelligent Keys.
The engine cannot be started by some Intelligent Keys>>Intelligent Key is low battery or malfunction. Refer
to BL-159, "
Intelligent Key Battery Replacement" .
The engine cannot be started by all Intelligent Keys>>GO TO 3.
The engine can be started by all Intelligent Keys>>GO TO 4.
3. CHECK “KEY” WARNING LAMP ILLUMINATION
When pushing the ignition switch, check if “KEY” warning lamp in combination meter illuminates.
KEY warning lamp illuminates green>>GO TO BL-114, "
KEY WARNING LAMP (GREEN) ILLUMINATES" .
KEY warning lamp illuminates red>>GO TO BL-114, "
KEY WARNING LAMP (RED) ILLUMINATES" .
Does not illuminate>>GO TO BL-115, "
KEY WARNING LAMP DOES NOT ILLUMINATE" .
4. START ENGINE WITH MECHANICAL KEY
Check if the engine could be started by all registered mechanical keys.
The engine can not be started by some mechanical keys>>Register mechanical key. Refer to CONSULT-II
operation manual.
The engine cannot be started by all mechanical keys>> BL-220, "
WORK FLOW" .
The engine can be started by all mechanical keys>>GO TO 5.
5. PERFORM SELF-DIAGNOSIS
1. Turn ignition switch to ON by carrying the Intelligent Key.
2. Perform self-diagnosis of Intelligent Key system with CONSULT-II.
Malfunction is detected>>GO TO B L - 111 , "

Revision: June 20062007 Versa
Precautions UCS005XJ
NOTE:
If any malfunction occurs in the RE0F08A 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. CVT-54, "
TCM INSPECTION TABLE".

After performing each TROUBLE DIAGNOSIS, perform
“DTC Confirmation Procedure”.
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 lint-free paper, 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 PrecautionsUCS005XK
CVT FLUID COOLER SERVICE
If CVT fluid contains friction material (clutches, brakes, etc.), or if an CVT is replaced, inspect and clean the
CVT fluid cooler mounted in the radiator or replace the radiator. Flush cooler lines using cleaning solvent and
compressed air after repair. For CVT fluid cooler cleaning procedure, refer to CVT-18, "
CVT Fluid Cooler
Cleaning" . For radiator replacement, refer to CO-11, "RADIATOR" .
