PRECAUTIONS
Revision: July 2006 2006 Quest
PRECAUTIONS PFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EES0022N
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 Man-
ual.
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 per-
formed by an authorized NISSAN/INFINITI dealer.
●Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal 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.

PAX Run Flat Tires and Wheels
EES0022M
CAUTION:
●Servicing PAX run flat tires and wheels requires special tire equipment and training. DO NOT ser-
vice PAX Run Flat tires and wheels with conventional tire servicing equipment or damage to the
tire and wheel will result.
●If a PAX run flat tire and wheel [or transmitter (pressure sensor)] requires service, and the proper
servicing equipment is not available, then replace the complete PAX tire and wheel assembly.
Conventional Tire and Wheel
EES0021J
BALANCING WHEELS
1. Remove inner and outer balance weights from the road wheel.
CAUTION:
Be careful not to scratch the road wheel during removal.
2. Using releasing agent, remove double-faced adhesive tape from the road wheel.
CAUTION:
●Be careful not to scratch the road wheel during removal.
●After removing double-faced adhesive tape, wipe clean traces of releasing agent from the road
wheel.
3. Set road wheel on wheel balancer using the center hole as a guide. Start the tire balance machine.
●If a tire balance machine has adhesion balance weight mode settings and drive-in weight mode setting,
select and adjust a drive-in weight mode suitable for road wheels.
4. When inner and outer unbalance values are shown on the wheel
balancer indicator, multiply outer unbalance value by 1.6 to
determine balance weight that should be used. Select the outer
balance weight with a value closest to the calculated value
above and install it to the designated outer position of, or at the
designated angle in relation to the road wheel.
CAUTION:
●Do not install the inner balance weight before installing
the outer balance weight.
●Before installing the balance weight, be sure to clean the
mating surface of the road wheel.
Calculation:
Indicated unbalance value × 1.6 = balance weight to be installed
Calculation example:
23 g (0.81 oz) × 1.6 = 38.33 g (1.35 oz) = 40 g (1.41 oz) balance weight (closer to calculated balance
weight value)
NOTE:
The selected balance weight value must be the closest balance weight available to the calculated balance
weight value.
Example:
37.4 = 35 g (1.23 oz)
37.5 = 40 g (1.41 oz)

a. Install balance weight in the position shown.
b. When installing balance weight to road wheels, set it into the
grooved area on the inner wall of the road wheel as shown in the
figure so that the balance weight center is aligned with the wheel
balancer indication position (angle).
CAUTION:
●Always use Genuine NISSAN adhesion balance weights.
●Balance weights are not reusable; always replace with
new ones.
●Do not install more than three pieces of balance weight.
c. If calculated balance weight value exceeds 50 g (1.76 oz), install
two balance weight pieces in line with each other (as shown in
the figure).
CAUTION:
Do not install one balance weight piece on top of another.
5. Start wheel balancer again.
6. Install drive-in balance weight on inner side of road wheel in the
wheel balancer indication position (angle).
CAUTION:
Do not install more than two balance weights.
7. Start wheel balancer. Make sure that inner and outer residual
unbalance values are 5 g (0.18 oz) each or less.
●If either residual unbalance value exceeds 5 g (0.18 oz), repeat installation procedures.
Wheel balance (Maximum allowable unbalance):
ROTATION
●After rotating the tires, adjust the tire pressure.
●Retighten the wheel nuts when the vehicle has been driven for
1,000 km (600 miles) (also in cases of a flat tire, etc.).
CAUTION:
When installing wheels, tighten them diagonally by dividing
the work two to three times in order to prevent the wheels
from developing any distortion.

REMOTE KEYLESS ENTRY RECEIVER
The remote keyless entry receiver receives the air pressure signal transmitted by the transmitter in each
wheel.
BCM (BODY CONTROL MODULE)
The BCM reads the air pressure signal received by the remote key-
less entry receiver, and controls the combination meter warning
lamp and the buzzer operations as shown below. It also has a judge-
ment function to detect a system malfunction.
COMBINATION METER
The combination meter receives tire pressure status from the BCM
using CAN communication. When a low tire pressure condition is
sensed by the BCM, the combination meter low tire pressure warn-
ing lamp and buzzer are activated.

●With ignition switch ON, as the hazard warning lamp flashes
per the follow diagram, the respective transmitter then must
be woken up.
2. When the BCM finishes assigning each tire ID, the BCM flashes the hazard warning lamps and trailer
flasher lamps (if equipped) and sends flashing indicator status by CAN according to the following time
chart. Please see trailer flasher specification details of trailer flashing lamps since the BCM controls trailer
flasher lamps as brake lamps. Refer to LT-132, "TRAILER TOW" .
3. After completing wake up of all transmitters, make sure low tire pressure warning lamp goes out.

Self-Diagnosis
EES0021T
DESCRIPTION
During driving, the low tire pressure warning system receives the signal transmitted from the transmitter
installed in each wheel, and gives alarms when the tire pressure becomes low. The control unit (BCM) for this
system has pressure judgement and trouble diagnosis functions.
FUNCTION
When the low tire pressure warning system detects low inflation pressure, the warning lamp in the combina-
tion meter comes on and the buzzer may sound (with PAX tires). To start the self-diagnostic results mode,
ground the terminal of the tire pressure warning check connector. The malfunction location is indicated by the
warning lamp flashing.

How to Perform Trouble Diagnosis for Quick and Accurate Repair
EES0021U
INTRODUCTION
●Before troubleshooting, verify customer complaints.
●If a vehicle malfunction is difficult to reproduce, harnesses, harness connectors or terminals may be mal-
functioning. Hold and shake these parts to make sure they are securely connected.
●When using a circuit tester to measure voltage or resistance of each circuit, be careful not to damage or
deform connector terminals.

CAUTION:
●Servicing PAX run flat tires and wheels requires special tire equipment and training. DO NOT ser-
vice PAX Run Flat tires and wheels with conventional tire servicing equipment or damage to the
tire and wheel will result.
●If a PAX run flat tire and wheel [or transmitter (pressure sensor)] requires service, and the proper
servicing equipment is not available, then replace the complete PAX tire and wheel assembly.
REMOVAL
1. Deflate tire. Unscrew transmitter retaining nut and allow transmitter to fall into tire.
2. Gently bounce tire so that transmitter falls to bottom of tire.
Place on tire changing machine and break both tire beads
ensuring that the transmitter remains at the bottom of the tire.
3. Turn tire so that valve hole is at bottom and bounce so that
transmitter is near valve hole. Carefully lift tire onto turntable and
position valve hole (and transmitter) 270 degrees from mount-
ing/dismounting head.
4. Lubricate tire well and remove first side of the tire. Reach inside
the tire and remove the transmitter.
INSTALLATION
1. Put first side of tire onto rim.
