< PRECAUTION >

TOW TRUCK TOWING

3.

Turn the steering wheel right and left to clear an area around the front tires.

4.

Slowly rock the vehicle forward and backward.
Shift back and forth between R (reverse) and D (drive).
Apply the accelerator as little as possible to maintain the rocking motion.
Release the accelerator pedal before shifting between R and D.
Do not spin the tires above 35 mph (55 km/h).

5.

If the vehicle can not be freed after a few tries, contact a professional towing service to remove the vehi-
cle.

PRECAUTIONS

• Never reverse polarity of battery terminals.
• Install only parts specified for a vehicle.
• Before replacing the control unit, check the input and output and functions of the component parts. 
• Do not apply excessive force when disconnecting a connector.

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 Service Manual 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:0000000000956203

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.
