REMOVAL AND INSTALLATION
Removal
1. Disconnect the battery negative terminal.
2. Remove engine under cover and fender protector (LH). Refer to EI-26, "
Removal and Installation".
3. Drain the A/T fluid. Refer to AT- 1 7
.
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 ma terial (clutch, bands, etc.),
replace radiator and flush cool er line using cleaning sol-
vent and compressed air after repair of A/T. Refer to CO-
40.
6. Remove magnets from oil pan.

TCM Power Supply (Memory Back-up)
Transaxle assembly is protected by limiting the engine torque when the memory back-up power supply (for
controlling) from the battery is not supplied to TCM.
Normal statues is restored when turning the ignition switch
OFF to ON after the normal power supply.
How to Perform Trouble Diagnosis for Quick and Accurate RepairINFOID:0000000005928750
INTRODUCTION
The TCM receives a signal from the vehicle speed sensor, transmission range switch and provides shift con-
trol or lock-up control via CVT solenoid valves.
The TCM also communicates with the ECM by means of a signal
sent from sensing elements used wit h the OBD-related parts of the
CVT system for malfunction-diagnos tic purposes. The TCM is capa-
ble of diagnosing malfunctioning parts while the ECM can store mal-
functions in its memory.
Input and output signals must always be correct and stable in the
operation of the CVT system. The CVT system must be in good
operating condition and be free of valve seizure, solenoid valve mal-
function, etc.
It is much more difficult to diagnose an error that occurs intermit-
tently rather than continuously. Most intermittent errors are caused
by poor electric connections or impr oper wiring. In this case, careful
checking of suspected circuits may help prevent the replacement of
good parts.
A visual check only may not find t he cause of the errors. A road test
with CONSULT-III (or GST) or a circuit tester connected should be
performed. Follow the "WORK FLOW" .
Before undertaking actual checks, take a few minutes to talk with a
customer who approaches with a driveability complaint. The cus-
tomer can supply good information about such errors, especially
intermittent ones. Find out what symptoms are present and under
what conditions they occur. A “DIAGNOSTIC WORKSHEET” as
shown on the example (Refer to "Diagnostic Worksheet Chart" )
should be used.
Start your diagnosis by looking for “conventional” errors first. This will
help troubleshoot driveability errors on an electronically controlled
engine vehicle.
Also check related Service bulletins.
WORK FLOW
A good understanding of the malfunction conditions can make troubleshooting faster and more accurate.
In general, each customer feels differently about a malf unction. It is important to fully understand the symp-
toms or conditions for a customer complaint.
Make good use of the two sheets provided, "Information From Customer" and "Diagnostic Worksheet Chart" ,
to perform the best troubleshooting possible.

P0456 EVAP CONTROL SYSTEM
• Use only a genuine NISSAN rubber tube as a replacement.
DTC CONFIRMATION PROCEDURE
1.INSPECTION START
Do you have CONSULT-III?
Do you have CONSULT-III?
YES >> GO TO 2.
NO >> GO TO 4.
2.PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at
least 10 seconds before conducting the next test.
NOTE:
• If DTC P0456 is displayed with P0442, firs t perform trouble diagnosis for DTC P0456.
• After repair, make sure that the hoses and clips are installed properly.
• Make sure that EVAP hoses are connected to EVAP canister purge volume control solenoid valve
properly.
TESTING CONDITION:
• Open engine hood before conducting following procedure.
• If any of following conditions are met just be fore the DTC CONFIRMATION PROCEDURE, leave the
vehicle for more than 1 hour.
- Fuel filler cap is removed.
- Fuel is refilled or drained.
- EVAP component parts is/are removed.
• Before performing the following procedure, confirm th at battery voltage is more than 11 V at idle.
>> GO TO 3.
3.PERFORM DTC CONFIRMATION PROCEDURE
With CONSULT-III
1. Turn ignition switch ON and select “DATA MONITOR” mode with CONSULT-III.
2. Make sure the following conditions are met.
FUEL LEVEL SE: 0.25 - 1.4 V
COOLAN TEMP/S: 0 - 32 °C (32 - 90° F)
FUEL T/TMP SE: 0 - 35° C (32 - 95°F)
INT A/TEMP SE: More than 0° C (32°F)
If NG, turn ignition switch OFF and leave the vehicle in a cool place (soak the vehicle) or refilling/draining
fuel until the output voltage condition of the “FUEL LEVEL SE” meets within the range above and leave
the vehicle for more than 1 hour. Then start from step 1.
3. Turn ignition switch OFF and wait at least 10 seconds.
4. Turn ignition switch ON.
5. Select “EVP V/S LEAK P0456/P1456” of “EVAPORATIVE SYSTEM” in “DTC WORK SUPPORT” mode with CONSULT-III.
Follow the instruction displayed.
NOTE:
If the engine speed canno t be maintained within the range displayed on CONSULT-III screen, go to
EC-20, "
BASIC INSPECTION : Special Repair Requirement".
Which is displayed on CONSULT-III?
OK >> INSPECTION END
NG >> Go to EC-341, "
Diagnosis Procedure".
4.PERFORM COMPONENT FUNCTION CHECK
Perform component function check. Refer to EC-341, "
Component Function Check".
NOTE:
Use component function check to check the overall function of the EVAP very small leak function. During this
check, a 1st trip DTC might not be confirmed.
Is the inspection result normal?
YES >> INSPECTION END
