REFRIGERANT PRESSURE SENSOR
Revision: 2007 April2007 M35/M45
REFRIGERANT PRESSURE SENSORPFP:92136
Component DescriptionNBS005Q7
The refrigerant pressure sensor (1) is installed at the condenser of
the air conditioner system. The sensor uses an electrostatic volume
pressure transducer to convert refrigerant pressure to voltage. The
voltage signal is sent to ECM, and ECM controls cooling fan system.

CONSULT-II CHECKING SYSTEM
Revision: 2007 April2007 M35/M45
Nickel Metal Hydride Battery Replacement NAS0007U
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 NAS0007V
When ordering the following equipment, contact your NISSAN/INFINITI distributor.
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.
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.
CONSULT-II Start ProcedureNAS0007W
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 nameDescription

TOW TRUCK TOWING
Revision: 2007 April2007 M35/M45
AW D M OD E LS
INFINITI recommends that a dolly be used as illustrated when towing AWD models.
CAUTION:
Never tow AWD models with any of the wheels on the ground as this may cause serious and expen-
sive damage to the powertrain.
Vehicle Recovery (Freeing a Stuck Vehicle) NAS00082
FRONT
Securely install the vehicle recovery hook stored with jacking tools.
Make sure that the hook is properly secured in the stored place after
use.
WARNING:

Stand clear of a stuck vehicle.

Do not spin your tires at high speed. This could cause them
to explode and result in serious injury. Parts of your vehicle
could also overheat and be damaged.
CAUTION:

Tow chains or cables must be attached only to the vehicle
recovery hooks or main structural members of the vehicle.
Otherwise, the vehicle body will be damaged.

Do not use the vehicle tie downs to free a vehicle stuck in sand, snow, mud, etc. Never tow the
vehicle using the vehicle tie downs or recovery hooks.

Always pull the cable straight out from the front of the vehicle. Never pull on the hook at an angle.

Pulling devices should be routed so they do not touch any part of the suspension, steering, brake
or cooling systems.

Pulling devices such as ropes or canvas straps are not recommended for use in vehicle towing or
recovery.
REAR
WARNING:

Rear hook is not available.
