DETAILED FLOW
1.COLLECT THE INFORMATION FROM THE CUSTOMER
It is also important to clarify customer complaints before inspection. First of all, reproduce symptoms, and
understand them fully. Ask customer about his/her complaints carefully. In some cases, it will be necessary to
check symptoms by driving vehicle with customer.
CAUTION:
Customers are not professional. It is dangerous to make an easy guess like “maybe the customer
means that...,” or “maybe the customer mentions this symptom”.

System Description INFOID:0000000000957227
DESCRIPTION
• Electronic control allows optimal distribution of torque to front/rear wheels to match road conditions.
• Makes possible stable driving, with no wheel spin, on snowy roads or other slippery surfaces.
• On roads which do not require AWD, it contributes to improved fuel economy by driving in conditions close to
rear-wheel drive.
• Sensor inputs determine the vehicle's turning condition, and in response tight cornering/braking are controlled by distributing optimum torque to front wheels.
• It transmits/receives each signal from the following control unit via CAN communication line.
Component parts Function
Transmits the following signals via CAN communication to AWD control unit.
ABS actuator and electric unit (control unit)
ECM
Unified meter and A/C amp.
NOTE:
• When driving, if there is a large difference between front and rear wheel speed which continues for a long
time, fluid temperature of drive system parts becomes too hi gh and AWD warning lamp blinks quickly. (When
AWD warning lamp blinks, vehicle changes to rear-wheel drive conditions.) Also, optional distribution of
torque sometimes becomes rigid before lamp blinks quickly, but it is not malfunction.
• If AWD warning lamp is blinking quickly, stop vehicle and allow it to idle for some time. Blinking will stop and
AWD system will be restored.
• Vehicle speed signal
• Stop lamp switch signal (brake signal)
Transmits the following signals via CAN communication to AWD control unit.
• Accelerator pedal position sign al
• Engine speed signal
Transmits conditions of parking brake switch via CAN communication to AWD control
unit.

AWD SYSTEM
Revision: October 2006
2007 G35 Sedan
< FUNCTION DIAGNOSIS >
• When driving, AWD warning lamp may blink slowly if there is a significant difference in diameter of the tires.
At this time, vehicle performance is not fully available and cautious driving is required. (Continues until
engine is turned OFF.)
• If the warning lamp blinks slowly during driving but remains OFF after engine is restarted, the system is normal. If it again blinks slowly after driving for some time, vehicle must be inspected.
• When the difference of revolution speed between the front and rear wheel the shift occasionally changes to
direct 4-wheel driving conditions automatically. This is not malfunction.
OPERATION PRINCIPLE
ELECTRIC CONTROLLED COUPLING
1. AWD control unit supplies command current to electric controlled coupling (AWD solenoid).
2. Control clutch is engaged by electromagnet and torque is detected in control clutch.
3. The cam operates in response to control clutch torque and applies pressure to main clutch.
4. Main clutch transmits torque to front wheels according to pressing power.
• Transmission torque to front wheels is determined according
to command current.

PRECAUTION
PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT PRE-TENSIONER" INFOID:0000000000957276
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Manual.
WARNING:
• To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in
the event of a collision which would result in air bag inflation, all maintenance must be performed by
an authorized NISSAN/INFINITI dealer.
• Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal
injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag
Module, see the SRS section.
• Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness connectors.
Service Notice or Precautions for Transfer INFOID:0000000000957277
CAUTION:
• Never reuse transfer fluid, once it has been drained.
• Check the fluid level or replace the fluid only with the vehicle parked on level ground.
• During removal or installation, keep inside of transfer clear of dust or dirt.
• Replace all tires at the same time. Always use tires of the proper size and the same brand and pattern. Fitting improper size and unusual wear tires applies excessive force to vehicle mechanism and
can cause longitudinal vibration.
• Disassembly should be done in a clean work area, it is preferable to work in dustproof area.
• Before proceeding with disassembly, thoroughly clean the transfer. It is important to prevent the
internal parts from becoming contaminated by dirt or other foreign matter.
• All parts should be carefully cleaned with a general purpose, non-flammable solvent before inspection or reassembly.
• Check for the correct installation status prior to removal or disassembly. If matching marks are
required, be certain they do not interfere with the function of the parts when applied.
• Check appearance of the disassembled parts for damage, deformation, and unusual wear. Replace
them with a new ones if necessary.
• Gaskets, seals and O-rings should be replaced any time when the transfer is disassembled.
• In principle, tighten bolts or nuts gradually in several steps working diagonally from inside to outside. If tightening sequence is specified, use it.
• Observe the specified torque when assembling.
• Clean and flush the parts sufficient ly and blow-dry them.
• Be careful not to damage sliding surfaces and mating surfaces.
• Clean inner parts with lint-free cloth or towels. Do not use cotton work gloves and rags to prevent
adhering fibers.

• Align matching marks to install propeller shaft rubber coupling to
final drive companion flange.
• After assembly, perform a driving test to check propeller shaft
vibration. If vibration occurred, separate propeller shaft from final
drive. Reinstall companion flange after rotating it by 120, 240
degrees. Then perform driving test and check propeller shaft vibration again at each point.
• If propeller shaft or final drive has been replaced, connect them as
follows:
- Install the propeller shaft (1) while aligning its matching mark (A)
with the matching mark (B) on the joint as close as possible.
