CONSULT-II CHECKING SYSTEM
Revision: August 20072004 QX56
Nickel Metal Hydride Battery Replacement EAS0014S
CONSULT-II contains a nickel metal hydride battery. When replacing the battery obey the following:
WAR NIN G:
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 EquipmentEAS0014T
When ordering the below equipment, contact your NISSAN 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 carries out CAN communication.
If CONSULT-II CONVERTER is not connected with CONSULT-II, the vehicle enters “FAIL SAFE
MODE” which will “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 ProcedureEAS0014U
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.
Tool name Description
NISSAN CONSULT-II (J-44200)
1. CONSULT-II unit (Tester internal soft: Resident
Version 3.4.0) and accessories.
2. Program card UED04D-1 and AEN04A-1 (for
NATS) or later, to confirm the best combination
of these software, refer to CONSULT-II Opera-
tion Manual.
3. CONSULT-II CONVERTER.
4. "CONSULT-II pigtail" cable.

INSPECTION PROCEDURE
If the CONSULT-II cannot diagnose the system properly, check the following items:
NOTE:
The preceding schematic is an example and may not be a true representation of the vehicle. The actual DDL1
circuits (CAN lines) from DLC pins 6 and 14 as well as the DDL2 circuit (K-line) from DLC pin 7 may be con-
nected 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 systems.
BCIA0029E
LAIA0028E
Symptom Check item
CONSULT-II cannot access
any system.
CONSULT-II DLC power supply circuit (Terminal 8) and ground circuit (Terminal 4). For detailed cir-
cuit, refer to LAN-5, "
CAN Communication Unit" .
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 GI-38, "
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 in CAN or K communication line. Refer to LAN-3, "Precautions When Using
CONSULT-II" .

POWER WINDOW CONTROL BY THE FRONT DOOR LOCK ASSEMBLY LH (KEY CYLINDER
SWITCH)
When ignition key switch is OFF, front power window LH and RH can be opened or closed by turning the front
door lock assembly LH (key cylinder switch) to the UNLOCK / LOCK position for more than 3 seconds.
Front power windows can be opened as the front door lock assembly LH (key cylinder switch) is kept fully
turned to the UNLOCK position.
Front power windows can be closed as the front door lock assembly LH (key cylinder switch) is kept fully
turned to the LOCK position.
While performing open/close operation for the windows, power window is stopped when the front door
lock assembly LH (key cylinder switch) is placed in the NEUTRAL position.
When the ignition switch is turned ON while the power window opening operation is performed, the power
window opening stops.
