< 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 points. To avoid
damaging the vehicle body, use proper towing equipment when
towing.
Vehicle Recovery (Freeing a stuck vehicle)
INFOID:0000000009480229
• 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 Service 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.

• 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:0000000009480233
