If repairs are needed always use wire that is of the same or larger gauge.
MEASURING VOLTAGE DROP — ACCUMULATED METHOD

Connect the DMM across the connector or part of the circuit you want to check. The positive lead of the
DMM should be closer to power and the negative lead closer to ground.

Operate the circuit.

The DMM will indicate how many volts are being used to “push” current through that part of the circuit.
Note in the illustration that there is an excessive 4.1 volt drop between the battery and the bulb.
MEASURING VOLTAGE DROP — STEP-BY-STEP
The step-by-step method is most useful for isolating excessive drops in low voltage systems (such as those in
“Computer Controlled Systems”).
Circuits in the “Computer Controlled System” operate on very low amperage.
The (Computer Controlled) system operations can be adversely affected by any variation in resistance in the
system. Such resistance variation may be caused by poor connection, improper installation, improper wire
gauge or corrosion.
The step by step voltage drop test can identify a component or wire with too much resistance.

Control Unit Circuit Test
System Description:When the switch is ON, the control unit lights up the lamp.
INPUT-OUTPUT VOLTAGE CHART
The voltage value is based on the body ground.
*:If high resistance exists in the switch side circuit (caused by a single strand), terminal 1 does not detect battery voltage. Control unit
does not detect the switch is ON even if the switch does not turn ON. Therefore, the control unit does not supply power to ligh t up the
lamp.
INPUT-OUTPUT VOLTAGE CHART
The voltage value is based on the body ground.
*:If high resistance exists in the switch side circuit (caused by a single strand), terminal 2 does not detect approx. 0V. Cont rol unit does
not detect the switch is ON even if the switch does not turn ON. Therefore, the control unit does not control ground to light u p the lamp.

Control Units and Electrical PartsAAS000E6
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.

If a connector is installed by tightening bolts, loosen bolt mount-
ing it, then take it out by hand.

Before installing a connector, make sure the terminal is not bent
or damaged, and then correctly connect it.
When installing a connector by tightening bolts, fix it by tighten-
ing the mounting bolt until the painted projection of the connec-
tor becomes even with the surface.

For removal of the lever type connector, pull the lever up to the
direction pointed to by the arrow A in the figure, and then
remove the connector.

For installation of the lever type connector, pull down the lever to
the direction pointed by the arrow B in the figure, and then push
the connector until a clicking noise is heard.

Do not apply excessive shock to the control unit by dropping or
hitting 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 vehicle.

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.

CONSULT-II CHECKING SYSTEM
Revision: 2005 July 2005 FX
Nickel Metal Hydride Battery Replacement AAS000E9
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 bat-
tery may present a risk of fire or explosion. The battery may present a fire or chemical burn hazard if
mistreated. Do not recharge, disassemble or dispose of in fire.
Keep the battery out of reach of children and discard used battery conforming to the local regulations.
Checking Equipment AAS000EA
When ordering the following equipment, contact your NISSAN/INFINITI distributor.
CAUTION:

If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carry out CAN communication.

If CONSULT-II CONVERTER is not connected with CONSULT-II, vehicle occur the “FAIL SAFE
MODE” which is “LIGHT UP the HEAD LIGHT” and/or “COOLING FAN ROTATING” when CON-
SULT-II is started.

Previous CONSULT-II “I” and “Y” DLC-I and DLC-II cables should NOT be used anymore because
their DDL connector pins can be damaged during cable swapping.
NOTE:

The CONSULT-II must be used in conjunction with a program card.
CONSULT-II does not require loading (Initialization) procedure.

Be sure the CONSULT-II is turned off before installing or removing a program card.
CONSULT-II Start ProcedureAAS000EB
NOTE:
Turning ignition switch off when performing CAN diagnosis could cause CAN memory to be erased.
1. Connect CONSULT-II and CONSULT-II CONVERTER to the data link connector.

Tow Truck TowingAAS000EH
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 to the vehicle during
towing operation. Towing is in accordance with Towing Procedure Manual 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 (that is backward) with four wheels on
the ground. This may cause serious and expensive damage to the transmission.
2WD MODELS
INFINITI recommends that vehicle be towed with the driving (rear) wheels off the ground or that a dolly be
used as illustrated.
CAUTION:

Never tow automatic transmission models with the rear wheels on the ground or four wheels on
the ground (forward or backward), as this may cause serious and expensive damage to the trans-
mission.
If it is necessary to tow the vehicle with the front wheels raised, always use towing dollies under
the rear wheels.

When towing rear wheel drive models with the front wheels on the ground or on towing dollies:
–Turn the ignition key to the OFF position, and secure the steering wheel in a straight ahead posi-
tion with a rope or similar device.Never secure the steering wheel by turning the ignition key to the
LOCK position. This may damage the steering lock mechanism.
–Move the selector lever to the N (Neutral) position.

When the battery of vehicle equipped with the Intelligent Key system is discharged, your vehicle
should be towed with the front wheels on towing dollies or place the vehicle on a flat bed truck.
If the speed or distance must necessarily be greater, remove the propeller shaft before towing to prevent dam-
age to the transmission.
