WARNING:

• Never get under the vehicle while it is supported only by the jack. Always use safety stands to sup-

port the frame when you have to get under the vehicle.

• Place wheel chocks at both front and back of the wheels on the ground.

CAUTION:

• All applicable State or Provincial (in Canada) laws and local laws regarding the towing operation

must be obeyed.

• It is necessary to use proper towing equipment to avoid possible damage during towing operation.

Towing is in accordance with Towing Procedure Instruction at dealer.

• Always attach safety chains before towing.
• When towing, make sure that the transmission, steering system and powertrain are in good order. If

any unit is damaged, dollies must be used.

• Never tow an automatic transmission model from the rear

(i.e., backward) with four wheels on the ground as this may
cause serious and expensive damage to the transmission.

2WD MODEL

NISSAN does not recommend towing automatic transmission
equipped vehicles with the drive wheels on the ground.

CAUTION:

• When towing with the front wheels on the ground: Turn the

ignition key to the OFF position and move the transmission
selector lever to N (neutral) position, turn the ignition key to
OFF position and secure the steering wheel in a straight
ahead position with a rope or similar device. Never place the
ignition key in the LOCK position. This will result in damage
to the steering lock mechanism.

< PRECAUTION >

TOW TRUCK TOWING

NISSAN recommends that towing dollies be used when towing 4WD
equipped vehicles or place the vehicle on a flat bed truck.

CAUTION:

• Never tow 4WD models with any of the wheels on the ground

as this may cause serious and expensive damage to the
transfer case and transmission.

Towing Point

CAUTION:

Never tow the vehicle using only the towing point, if equipped.
To avoid damaging the vehicle body, use proper towing equip-
ment when towing.

Vehicle Recovery (Freeing a Stuck Vehicle)

INFOID:0000000003938073

• Tow chains or cables must be attached only to the main structural members of the vehicle.
• Pulling devices should be routed so they do not touch any part of the suspension, steering, brake or

cooling systems

• Always pull the cable straight out from the front or rear of the vehicle. Never pull the vehicle at a

sideways angle.

• Pulling devices such as ropes or canvas straps are not recommended for use for vehicle towing or

recovery.

STEP

DESCRIPTION

STEP 1

Get detailed information about the conditions and the environment when the incident occurred.
The following are key pieces of information required to make a good analysis:

WHAT

Vehicle Model, Engine, Transmission/Transaxle and the System (i.e. Radio).

WHEN

Date, Time of Day, Weather Conditions, Frequency.

WHERE

Road Conditions, Altitude and Traffic Situation.

HOW

System Symptoms, Operating Conditions (Other Components Interaction). 
Service History and if any After Market Accessories have been installed. 

STEP 2

Operate the system, road test if necessary.
Verify the parameter of the incident.
If the problem cannot be duplicated, refer to “Incident Simulation Tests”.

STEP 3

Get the proper diagnosis materials together including:
• Power Supply Routing
• System Operation Descriptions
• Applicable Instruction Sections
• Check for any Service Bulletins
Identify where to begin diagnosis based upon your knowledge of the system operation and the customer comments.

STEP 4

Inspect the system for mechanical binding, loose connectors or wiring damage.
Determine which circuits and components are involved and diagnose using the Power Supply Routing and Harness Lay-
outs.

STEP 5

Repair or replace the incident circuit or component.

STEP 6

Operate the system in all modes. Verify the system works properly under all conditions. Make sure you have not inad-
vertently created a new incident during your diagnosis or repair steps.

SERVICE INFORMATION FOR ELECTRICAL INCIDENT

• Do not apply excessive shock to the control unit by dropping or hit-

ting it.

• Be careful to prevent condensation in the control unit due to rapid

temperature changes and do not let water or rain get on it. If water
is found in the control unit, dry it fully and then install it in the vehi-
cle.

• Be careful not to let oil to get on the control unit connector.
• Avoid cleaning the control unit with volatile oil.
• Do not disassemble the control unit, and do not remove the upper

and lower covers.

• When using a DMM, be careful not to let test probes get close to

each other to prevent the power transistor in the control unit from
damaging battery voltage because of short circuiting.

• When checking input and output signals of the control unit, use the

specified check adapter.

How to Check Terminal

INFOID:0000000003938076

CONNECTOR AND TERMINAL PIN KIT

• Use the connector and terminal pin kits listed below when replacing connectors or terminals.
• The connector and terminal pin kits contain some of the most commonly used NISSAN/INFINITI connectors

and terminals. For detailed connector and terminal pin replacement procedures, refer to the latest NISSAN/
INFINITI CONNECTOR AND TERMINAL PIN SERVICE MANUAL.

HOW TO PROBE CONNECTORS

• Connector damage and an intermittent connection can result from improperly probing of the connector dur-

ing circuit checks.

• The probe of a digital multimeter (DMM) may not correctly fit the connector cavity. To correctly probe the

connector, follow the procedures below using a “T” pin. For the best contact grasp the “T” pin using an alliga-
tor clip.

Probing from Harness Side 

Standard type (not waterproof type) connector should be probed
from harness side with “T” pin.
• If the connector has a rear cover such as a ECM connector,

remove the rear cover before probing the terminal.

• Do not probe waterproof connector from harness side. Damage to

the seal between wire and connector may result.

Probing from Terminal Side 

FEMALE TERMINAL

• There is a small notch above each female terminal. Probe each

terminal with the “T” pin through the notch.
Do not insert any object other than the same type male terminal
into female terminal.

SERVICE INFORMATION FOR ELECTRICAL INCIDENT

• Some connectors do not have a notch above each terminal. To

probe each terminal, remove the connector retainer to make con-
tact space for probing.

MALE TERMINAL

• Carefully probe the contact surface of each terminal using a “T”

pin.

CAUTION:

Dot not bend terminal.

How to Check Enlarged Contact Spring of Terminal

• An enlarged contact spring of a terminal may create intermittent signals in the circuit.
• If the intermittent open circuit occurs, follow the procedure below to inspect for open wires and enlarged con-

tact spring of female terminal.

1.

Assemble a male terminal and approx. 10 cm (3.9 in) of wire.
NOTE:
Use a male terminal which matches the female terminal.

2.

Disconnect the suspected faulty connector and hold it terminal
side up.

3.

While holding the wire of the male terminal, try to insert the male
terminal into the female terminal.

CAUTION:

Do not force the male terminal into the female terminal with
your hands.

4.

While moving the connector, check whether the male terminal
can be easily inserted or not.

• If the male terminal can be easily inserted into the female ter-

minal, replace the female terminal.

Waterproof Connector Inspection 

If water enters the connector, it can short interior circuits. This may lead to intermittent problems.
Check the following items to maintain the original waterproof characteristics.

RUBBER SEAL INSPECTION

• Most waterproof connectors are provided with a rubber seal

between the male and female connectors. If the seal is missing,
the waterproof performance may not meet specifications.

• The rubber seal may come off when connectors are disconnected.

Whenever connectors are reconnected, make sure the rubber seal
is properly installed on either side of male or female connector.

WIRE SEAL INSPECTION

• The wire seal must be installed on the wire insertion area of a

waterproof connector. Be sure that the seal is installed properly.

Terminal Lock Inspection 

Check for unlocked terminals by pulling wire at the end of connector.
An unlocked terminal may create intermittent signals in the circuit.

Intermittent Incident

INFOID:0000000003938077

DESCRIPTION

Sometimes the symptom is not present when the vehicle is brought in for service. If possible, re-create the
conditions present at the time of the incident. Doing so may help avoid a No Trouble Found Diagnosis. The fol-
