PRECAUTION
PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER" INFOID:0000000009723907

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. Information necessary to service the system safely is included in the SR and SB section of
this Service Manual.
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 SR 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.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
• When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or electric power tools or strike near the sensor(s) with a
hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing
serious injury.
• When using air or electric power tools or hammers, always switch the Ignition OFF, disconnect the
battery and wait at least three minutes before performing any service.
Precaution for Procedure without Cowl Top Cover INFOID:0000000009177469

When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc to prevent damage to
windshield.

Precaution for TCM and Transaxle Assembly Replacement INFOID:0000000009177470

CAUTION:
• To replace TCM, refer to TM-81, "Description".
• To replace transaxle assembly, refer to TM-82, "Description".

Revision: May 2013 TM-6 2014 Pathfinder

 PRECAUTIONS
< PRECAUTION > [CVT: RE0F10E]
General Precautions INFOID:0000000009177471

A
• Turn ignition switch OFF and disconnect the battery cable
from the negative terminal before connecting or disconnect-
ing the CVT assembly harness connector. Because battery B
voltage is applied to TCM even if ignition switch is turned
OFF.

TM
SEF289H

• When connecting or disconnecting pin connectors into or E

from TCM, do not damage pin terminals (bend or break).
Check that there are not any bends or breaks on TCM pin ter-
minal, when connecting pin connectors. F

AAT470A H

• Perform TCM input/output signal inspection and check

whether TCM functions normally or not before replacing TCM. I
Refer to TM-48, "Reference Value".

MEF040DA
L
• Perform “DTC (Diagnostic Trouble Code) CONFIRMATION
PROCEDURE”.
If the repair is completed DTC should not be displayed in the M
“DTC CONFIRMATION PROCEDURE”.

O
JSBIA1315ZZ

P
• Always use the specified brand of CVT fluid. Refer to MA-15, "FOR USA AND CANADA : Fluids and Lubri-
cants" (For USA and Canada), MA-16, "FOR MEXICO : Fluids and Lubricants" (For Mexico).
• Use lint-free paper not cloth rags during work.
• Dispose of the waste oil using the methods prescribed by law, ordinance, etc. after replacing the CVT fluid.

Revision: May 2013 TM-7 2014 Pathfinder

 PRECAUTIONS
< PRECAUTION > [CVT: RE0F10E]
On Board Diagnosis (OBD) System of CVT and Engine INFOID:0000000009177472

The TCM and ECM have 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 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 EGR 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.
Removal and Installation Procedure for CVT Unit Connector INFOID:0000000009177473

REMOVAL
• Rotate bayonet ring counterclockwise. Pull out CVT unit har-
ness connector upward and remove it.

TRANSAXLE : Transaxle Mechanism INFOID:0000000009177501

TORQUE CONVERTER (WITH LOCK-UP FUNCTION)

In the same way as a conventional A/T, the torque converter is a system that increases the engine torque and
transmits the torque to the transaxle. A symmetrical 3-element, 1-stage, 2-phase type is used here.
OIL PUMP
Utilizes a vane-type oil pump that is driven by the engine through the oil pump drive chain in order to increase
efficiency of pump discharge volume in low-speed zone and optimize pump discharge volume in high-speed
zone. Discharged oil from oil pump is transmitted to control valve. It is used as the oil of primary and second-
ary pulley operation, the oil of clutch operation, and the lubricant for each part.
PLANETARY GEAR
• A planetary gear type of forward/reverse selector mechanism is installed between the torque converter and
primary pulley.
• The power from the torque converter is input via the input shaft, operating a wet multi-plate clutch by means
of hydraulic pressure to switch between forward and reverse driving.
Operation of Planetary gear

JSDIA2426GB

BELT & PULLEY

It is composed of a pair of pulleys (the groove width is changed freely in the axial direction) and the chain belt
.The groove width changes according to wrapping radius of chain belt and pulley from low status to overdrive
status continuously with non-step. It is controlled with the oil pressures of primary pulley and secondary pulley.
Chain belt
The chain belt consists of approximately 150 locker pins and
1,000 link plates . Chains are rotated by locker pins sandwiched by
pulleys. This produces tension difference in chains among pulleys.
Accordingly, the power is transferred by the tension.

JSDIA3643ZZ

Pulley
The primary pulley (input shaft side) and the secondary pulley (output shaft side) have the shaft with slope
(fixed cone surface), movable sheave (movable cone surface that can move in the axial direction) and oil pres-
sure chamber at the back of the movable sheave.

Revision: May 2013 TM-22 2014 Pathfinder

 STRUCTURE AND OPERATION
< SYSTEM DESCRIPTION > [CVT: RE0F10E]
• The CVT oil warmer is installed on the front part of transaxle
assembly. A
• When engine is started while engine and CVT are cold, engine
coolant temperature rises more quickly than CVT fluid tempera-
ture. CVT oil warmer is provided with two circuits for CVT and
B
engine coolant respectively so that warmed engine coolant warms
CVT quickly. This helps shorten CVT warming up time, improving
fuel economy.
• A cooling effect is obtained when CVT fluid temperature is high. C

TM
CVT Fluid Cooler
• The CVT fluid cooler is installed to the vehicle front LH.
• The CVT fluid cooler prevents CVT fluid temperature from an
abnormal increase while driving the vehicle. When flowing into the E
CVT fluid cooler, CVT fluid is cooled by driving blast while driving
the vehicle.

SHIFT LOCK SYSTEM

SHIFT LOCK SYSTEM : System Description INFOID:0000000009177506

The shift lever cannot be shifted from the “P” position unless the brake pedal is depressed while the ignition
switch is set to ON. The shift lock is unlocked by turning the shift lock solenoid ON when the ignition switch is
set to ON, the park position switch is turned ON (selector lever is in “P” position), and the stop lamp switch is
turned ON (brake pedal is depressed) as shown in the operation chart in the figure. Therefore, the shift lock
solenoid receives no ON signal and the shift lock remains locked if all of the above conditions are not fulfilled.
However, selector operation is allowed if the shift lock release button is pressed.

SHIFT LOCK OPERATION AT “P” POSITION

When Brake Pedal Is Not Depressed (No Selector Operation Allowed)

The shift lock solenoid (A) is turned OFF (not energized) and the
solenoid rod (B) is extended with the spring when the brake pedal is
not depressed (no selector operation allowed) with the ignition
switch ON.
The connecting lock lever (C) is located at the position shown in the
figure when the solenoid rod is extended. It prevents the movement
of the detent rod (D). For these reasons, the selector lever cannot be
shifted from the “P” position.

Revision: May 2013 TM-28 2014 Pathfinder

 STRUCTURE AND OPERATION
< SYSTEM DESCRIPTION > [CVT: RE0F10E]
The shift lock solenoid (A) is turned ON (energized) when the brake
pedal is depressed with the ignition switch ON. The solenoid rod (B) A
is compressed by the electromagnetic force. The connecting lock
lever (C) rotates when the solenoid is activated. Therefore, the
detent rod (D) can be moved. For these reasons, the selector lever
B
can be shifted to other positions.

TM
“P” POSITION HOLD MECHANISM (IGNITION SWITCH LOCK)
The shift lock solenoid (A) is not energized when the ignition switch
is in any position other than ON. In this condition, the shift mecha-
nism is locked and “P” position is held. The operation cannot be per- E
formed from “P” position if the brake pedal is depressed with the
ignition switch ON when the operation system of shift lock solenoid is
malfunctioning. However, the lock lever (B) is forcibly rotated and the F
shift lock is released when the shift lock release button (C) is
pressed from above. Then the selector operation from “P” position
can be performed.

CVT CONTROL SYSTEM : Protection Control INFOID:0000000009177509

The TCM becomes the protection control status temporarily to protect the safety when the safety of TCM and
transmission is lost. It automatically returns to the normal status if the safety is secured.
The TCM has the following protection control.
CONTROL FOR WHEEL SPIN

When a wheel spin is detected, the engine output and gear ratio are limited and the line pressure is increased.

Shift Position Function
• D Position (Normal)
Gear shifting is performed in all shifting ranges from the lowest to B
the highest gear ratio.

TM

SCIA1953E E

• D Position (OD OFF)

The gear ratio is generally high by limiting the shifting range on the F
high side, and this always generates a large driving power.

• L Position
By limiting the shifting range only to the lowest of the gear ratio, a J
large driving force and engine brake are obtained.

SCIA8240E M
Hill Climbing And Descending Control
If a downhill is detected with the accelerator pedal is released, the system performs downshift to increase the
engine brake force so that vehicle may not be accelerated more than necessary. If a climbing hill is detected, N
the system improves the acceleration performance in re-acceleration by limiting the gear shift range on the
high side.
NOTE: O
For engine brake control on a downhill, the control can be stopped with CONSULT.

Control In Acceleration
From change of the vehicle speed or accelerator pedal position, the acceleration request level of the driver or
driving scene is evaluated. In start or acceleration during driving, the gear shift characteristics with linearity of
revolution increase and vehicle speed increase are gained to improve the acceleration feel.
Tow Mode
• In tow mode, sluggish acceleration and insufficient engine brake output resulting from towing are assisted
and improved by CVT gear shifting.
• When all of the following conditions are satisfied, CVT goes into tow mode.

DESCRIPTION
• Controls for improvement of the transmission efficiency by engaging the torque converter clutch in the K
torque converter and eliminating slip of the converter. Achieves comfortable driving with slip control of the
torque converter clutch.
• The oil pressure feed circuit for the torque converter clutch piston chamber is connected to the torque con- L
verter clutch control valve. The torque converter clutch control valve is switched by the torque converter
clutch solenoid valve with the signal from TCM. This controls the oil pressure circuit, which is supplied to the
torque converter clutch piston chamber, to the release side or engagement side.
• If the CVT fluid temperature is low or the vehicle is in fail-safe mode due to malfunction, lock-up control is M
prohibited.
Lock-up engagement

In lock-up engagement, the torque converter clutch solenoid valve makes the torque converter clutch control
valve locked up to generate the lock-up apply pressure. This pushes the torque converter clutch piston for
engagement.

Lock-up release condition
In lock-up release, the torque converter clutch solenoid valve makes the torque converter clutch control valve
non-locked up to drain the lock-up apply pressure. This does not engage the torque converter clutch piston.

CONSULT DATA MONITOR STANDARD VALUE

• In CONSULT, electric shift timing or lock-up timing, i.e. operation timing of each solenoid valve, is displayed.
Therefore, if there is an obvious difference between the shift timing estimated from a shift shock (or engine
speed variations) and that shown on the CONSULT, the mechanism parts (including the hydraulic circuit)
excluding the solenoids and sensors may be malfunctioning. In this case, check the mechanical parts follow-
ing the appropriate diagnosis procedure.
• Shift point (gear position) displayed on CONSULT slightly differs from shift pattern described in Service Man-
ual. This is due to the following reasons.
- Actual shift pattern may vary slightly within specified tolerances.
- While shift pattern described in Service Manual indicates start of each shift, CONSULT shows gear position
at end of shift.
- The solenoid display (ON/OFF) on CONSULT is changed at the start of gear shifting. In contrast, the gear

Protection Control INFOID:0000000009177523

The TCM becomes the protection control status temporarily to protect the safety when the safety of TCM and
transmission is lost. It automatically returns to the normal status if the safety is secured.
The TCM has the following protection control.
CONTROL FOR WHEEL SPIN

When a wheel spin is detected, the engine output and gear ratio are limited and the line pressure is increased.
Control
Limits engine output when a wheel spin occurs in any of right and left drive wheels.
Vehicle behavior in If the accelerator is kept depressing during wheel spin, the engine revolution and vehicle speed are limited to
control a certain degree.
Normal return condi-
Wheel spin convergence returns the control to the normal control.
tion

TORQUE IS REDUCED WHEN DRIVING WITH THE REVERSE GEAR

Control Engine output is controlled according to a vehicle speed while reversing the vehicle.
Vehicle behavior in
Power performance may be lowered while reversing the vehicle.
control
Normal return condi-
Torque returns to normal by positioning the selector lever in a range other than “R” position.
tion

CONTROL WHEN FLUID TEMPERATURE IS HIGH

When the CVT fluid temperature is high, the gear shift permission maximum revolution and the maximum
Control
torque are reduced than usual to prevent increase of the oil temperature.
Vehicle behavior in
Power performance may be lowered, compared to normal control.
control
Normal return condi-
The control returns to the normal control when CVT fluid temperature is lowered.
tion

REVERSE PROHIBIT CONTROL

The reverse brake is controlled to avoid becoming engaged when the selector lever is set in “R” position while
Control
driving in forward direction at more than the specified speed.
Vehicle behavior in If the selector lever is put at “R” position when driving with the forward gear, the gear becomes neutral, not
control reverse.
Normal return condi- The control returns to normal control when the vehicle is driven at low speeds. (The reverse brake becomes
tion engaged.)

CVT FLUID COOLER SYSTEM
Cleaning INFOID:0000000009177534

Whenever an automatic transaxle is repaired, overhauled, or replaced, the CVT fluid cooler mounted in the
radiator must be inspected and cleaned.
Metal debris and friction material, if present, can be trapped or be deposited in the CVT fluid cooler. This
debris can contaminate the newly serviced CVT or, in severe cases, can block or restrict the flow of CVT fluid.
In either case, malfunction of the newly serviced CVT may occur.
Debris, if present, may deposit as CVT fluid enters the cooler inlet. It will be necessary to back flush the cooler
through the cooler outlet in order to flush out any built up debris.
CVT FLUID COOLER CLEANING PROCEDURE
1. Position an oil pan under the transaxle's inlet and outlet cooler hoses.
2. Identify the inlet and outlet fluid cooler hoses.
3. Disconnect the fluid cooler inlet and outlet rubber hoses from the
steel cooler tubes or bypass valve.
NOTE:
Replace the cooler hoses if rubber material from the hose
remains on the tube fitting.
4. Allow any CVT fluid that remains in the cooler hoses to drain into
the oil pan.

SCIA4421E

5. Insert the extension adapter hose of a can of Transmission

Cooler Cleaner (Nissan P/N 999MP-AM006) into the cooler out-
let hose.
CAUTION:
• Wear safety glasses and rubber gloves when spraying the
Transmission Cooler Cleaner.
• Spray Transmission Cooler Cleaner only with adequate
ventilation.
• Avoid contact with eyes and skin.
• Never breath vapors or spray mist.
6. Hold the hose and can as high as possible and spray Transmis- SCIA4422E
sion Cooler Cleaner in a continuous stream into the cooler outlet
hose until CVT fluid flows out of the cooler inlet hose for 5 seconds.
7. Insert the tip of an air gun into the end of the cooler outlet hose.
8. Wrap a shop rag around the air gun tip and end of the cooler
outlet hose.
9. Blow compressed air regulated to 5 to 9 kg/cm2 (70 to 130 psi)
through the cooler outlet hose for 10 seconds to force out any
remaining CVT fluid.
10. Repeat steps 5 through 9 three additional times.
11. Position an oil pan under the banjo bolts that connect the CVT
fluid cooler steel lines to the transaxle.
12. Remove the banjo bolts. SCIA4423E

13. Flush each steel line from the cooler side back toward the tran-
saxle by spraying Transmission Cooler Cleaner in a continuous stream for 5 seconds.
14. Blow compressed air regulated to 5 to 9 kg/cm2 (70 to 130 psi) through each steel line from the cooler
side back toward the transaxle for 10 seconds to force out any remaining CVT fluid.

< DTC/CIRCUIT DIAGNOSIS > [CVT: RE0F10E]
U1000 CAN COMM CIRCUIT
Description INFOID:0000000009177552

CAN (Controller Area Network) is a serial communication line for real-time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent malfunction detection ability.
Many electronic control units are equipped onto a vehicle, and each control unit shares information and links
with other control units during operation (not independently). In CAN communication, control units are con-
nected with 2 communication lines (CAN-H line, CAN-L line) allowing a high rate of information transmission
with less wiring. Each control unit transmits/receives data but selectively reads required data only.
