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 light 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. Control 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 up 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 SYSTEMPFP:00000
DescriptionAAS000E7
CONSULT-II is a hand-held type tester. When it is connected with a diagnostic connector equipped on the
vehicle side, it will communicate with the control unit equipped in the vehicle and then enable various
kinds of diagnostic tests.
Refer to “CONSULT-II Software Operation Manual” for more information.

CONSULT-II CHECKING SYSTEM
Revision: 2004 November 2004 FX35/FX45
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:
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.
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.
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 can be erased.
1. Connect CONSULT-II and CONSULT-II CONVERTER to the
data link connector.

INSPECTION PROCEDURE
If the CONSULT-II cannot diagnose the system properly, check the following items.
NOTE:
The DDL1 and DDL2 circuits from DLC pins 12, 13, 14 and 15 may be connected to more than one system. A
short in a DDL circuit connected to a control unit in one system may affect CONSULT-II access to other sys-
tems.
Symptom Check item
CONSULT-II cannot access
any system.
CONSULT-II DLC power supply circuit (Terminal 8) and ground circuit (Terminal 4) (For detailed
circuit, refer to “MIL & Data Link Connectors Wiring Diagram” in EC section.)
CONSULT-II DLC cable and CONSULT-II CONVERTER
CONSULT-II cannot access
individual system. (Other sys-
tems can be accessed.)
CONSULT-II program card (Check the appropriate CONSULT-II program card for the system.
Refer to "Checking Equipment".)
Power supply and ground circuit for the control unit of the system (For detailed circuit, refer to wir-
ing diagram for each system.)
Open or short circuit between the system and CONSULT-II DLC (For detailed circuit, refer to wiring
diagram for each system.)
Open or short circuit CAN communication line. Refer to LAN-4, "Precautions When Using CON-
SULT-II" .
