Engine compartment
There are several reasons a vehicle or engine vibration could
cause an electrical complaint. Some of the things to check for are:
IConnectors not fully seated.
IWiring harness not long enough and is being stressed due to
engine vibrations or rocking.
IWires laying across brackets or moving components.
ILoose, dirty or corroded ground wires.
IWires routed too close to hot components.
To inspect components under the hood, start by verifying the integ-
rity of ground connections. (Refer to GROUND INSPECTION
described later.) First check that the system is properly grounded.
Then check for loose connection bygently shakingthe wiring or
components as previously explained. Using the wiring diagrams
inspect the wiring for continuity.
Behind the instrument panel
An improperly routed or improperly clamped harness can become
pinched during accessory installation. Vehicle vibration can aggra-
vate a harness which is routed along a bracket or near a screw.
Under seating areas
An unclamped or loose harness can cause wiring to be pinched by
seat components (such as slide guides) during vehicle vibration. If
the wiring runs under seating areas, inspect wire routing for pos-
sible damage or pinching.
HEAT SENSITIVE
The owner's problem may occur during hot weather or after car has
sat for a short time. In such cases you will want to check for a heat
sensitive condition.
To determine if an electrical component is heat sensitive, heat the
component with a heat gun or equivalent.
Do not heat components above 60ÉC (140ÉF).If incident occurs
while heating the unit, either replace or properly insulate the com-
ponent.

Nickel Metal Hydride Battery Replacement
CONSULT-II contains a nickel metal hydride battery. When replacing the battery obey the following:
WARNING:
Replace the nickel metal hydride battery with genuine CONSULT-II battery only. Use of another battery
may present a risk of fire or explosion. The battery may present a fire or chemical burn hazard if mis-
treated. Do not recharge, disassemble of dispose of in fire.
Keep the battery out of reach of children and discard used battery conforming to the local regulations.
Checking Equipment
When ordering this equipment, contact your NISSAN distributor.

4-pole Lift
WARNING:
Do not use a 2-pole lift.
Due to weight balance of the vehicle and shape of underbody,
lift arms can not be attached in a safe way. Therefore it is rec-
ommended to use a 4-pole lift only.
Tow Truck Towing
CAUTION:
IAll applicable local laws regarding the towing operation
must be obeyed.
IIt is necessary to use proper towing equipment to avoid
possible damage to the vehicle during a towing operation.
IAttach safety chains for all towing.
IWhen towing, make sure that the transmission, steering
system and power train are in good order. If any unit is
damaged, a dolly must be used.
IWhen towing with the front wheels on the ground:
Move both the gearshift and transfer levers to neutral (ªNº
position).
Turn the ignition key to the ªOFFº position and secure the
steering wheel in a straightahead position with a rope or
similar device. Never place the ignition key in the ªLOCKº
position. This will result in damage to the steering lock
mechanism.
IWhen towing with the rear wheels on the ground, release
the parking brake and move both the gearshift and trans-
fer levers to neutral (ªNº position).
INever tow vehicle from the rear (i.e., backward) with four
wheels on the ground as this may cause serious and
expensive damage to the transmission.
