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.

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.
●
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.

Description
NAS00042
●
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.
Function and System Application

x: Applicable
*1: IVIS (NATS) [INFINITI Vehicle Immobilizer system (NISSAN Anti-Theft System)]
Nickel Metal Hydride Battery Replacement
NAS00044
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.

CONSULT-II CHECKING SYSTEM
Checking Equipment
NAS00045
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 Procedure
NAS00072
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.
2.
If necessary, turn on the ignition switch.
3.
Touch “START(NISSAN BASED VHCL)” or System Shortcut key
