Removal and InstallationINFOID:0000000009460692
WARNING:
• Perform the procedure with the exhaust system fu lly cooled down because the system will be hot
just after the engine is turned off.
• Be careful not to cut your hand on the insulator edges.
CAUTION:
• Use Genuine NISSAN exhaust system parts or equival ent, which are specifically designed for heat
resistance, corrosion resistance, and shape.
REMOVAL
Remove exhaust system components using power tool.
• Remove heated oxygen sensor using Tool as needed.
INSTALLATION
Installation is in the reverse order of removal.
CAUTION:
• Always replace exhaust gaskets with new ones when reassembling.
• Before installing a new heated o xygen sensor, clean and lube the exhaust tube threads using suit-
able tool.
• Discard any heated oxygen sensor which has been dr opped from a height of more than 0.5 m (19.7
in) onto a hard surface such as a concrete floor; install a new one.
• Do not over-tighten the heated oxygen sensor. Doing so may damage the heated oxygen sensor,
resulting in the MIL coming on.
• If any mounting insulator is badly deformed, repair or replace it. If deposits such as mud pile up on
the mounting insulator, clean and inspect them.
• When installing the insulator avoid large gaps or interference between the insulator and each
exhaust pipe.
• Remove deposits from the sealing surface of each connection. Connect them securely to avoid
exhaust gas leaks.
• Temporarily tighten the exhaust manifold side nut s and the vehicle side bolts. Check each part for
any interference, and then tighten th e nuts and bolts to specification.
• When installing each mounting ru bber, avoid twisting or excessive ext ension in up/down and right/
left directions.
• Tighten the bolts without causing interference with the flange.
Inspection After InstallationINFOID:0000000009460693
• With the engine running, check the exhaust tube joints for exhaust gas leaks and unusual noises.
• Check that the mounting brackets and mounting insula tors are installed properly and free from excessive
stress. Improper installation could result in excessive noise, leaks, and vibration.

PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000009951582
The Supplemental Restraint System such as “A IR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severi ty of injury to the driver and front passenger for certain
types of collision. Information necessary to service the system safely is included in the SR and SB section of
this Service Manual.
WARNING:
• To avoid rendering the SRS inopera tive, 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 NISS AN/INFINITI dealer.
• Improper maintenance, including in correct removal and installation of the SRS, can lead to personal
injury caused by unintent ional activation of the system. For re moval of Spiral Cable and Air Bag
Module, see the SR section.
• Do not use electrical test equipmen t on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harn esses can be identified by yellow and/or orange harnesses or har-
ness connectors.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
• When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or electri c power tools or strike near the sensor(s) with a
hammer. Heavy vibration could activate the sensor( s) and deploy the air bag(s), possibly causing
serious injury.
• When using air or electric power tools or hammers , always switch the Ignition OFF, disconnect the
battery and wait at least three minutes before performing any service.
General precautions fo r service operationsINFOID:0000000009463538
• Do not work with wet hands.
• The xenon headlamp system includes a high voltage generating
part. Be sure to disconnect batte ry negative cable (negative termi-
nal) or power fuse before removing, installing, or touching the
xenon headlamp (including lamp bulb).
• Turn the lighting switch OFF before disconnecting and connecting the connector.
• When turning the xenon headlamp on and while it is illuminated, do
not touch the harness, bulb, and socket of the headlamp.
• When checking the headlamp on/off operation, check it on vehicle and with the power connected to the vehicle-side connector.
• Do not touch the headlamp bulb glass surface with bare hands or allow oil or grease to get on it. Do not touch the headl amp bulb just after the headlamp is turned off, because
it is very hot.
• Install the xenon headlamp bulb socket co rrectly. If it is installed improperly, high-voltage leak or corona dis-
charge may occur that can melt the bulb, connector or housing. Do not illuminate the xenon headlamp bulb
out of the headlamp housing. Doing so can cause fire and harm your eyes.
• When the bulb has burned out, wrap it in a thick vinyl bag and discard. Do not break the bulb.
• Leaving the bulb removed from the headlamp housing for a long period of time can deteriorate the perfor- mance of the lens and reflector (dirt, clouding). Al ways prepare a new bulb and have it on hand when replac-
ing the bulb.
• When adjusting the headlamp aiming, turn the aiming adjus tment screw only in the tightening direction. If it
is necessary to loosen the screw, first fully loosen the screw, and then turn it in the tightening direction.
• Do not use organic solvent (paint thinner or gasoline) to clean lamps and to remove old sealant.

< SYSTEM DESCRIPTION >
SYSTEM
HIGH BEAM OPERATION/FLASH-TO-PASS OPERATION
With the lighting switch in the 2nd position and placed in HIGH position, the BCM receives input requesting the
headlamp high beams to illuminate. The flash to pass f eature can be used any time and also sends a signal to
the BCM. This input is communicated to the IPDM E/R across the CAN communication lines. The CPU of the
combination meter controls the ON/OFF status off the HIGH BEAM indicator. The CPU of the IPDM E/R con-
trols the headlamp high relay coil which supplies power to the high beam headlamps.
The combination meter receives a high beam request signal (ON) through the CAN communication lines and
turns the high beam indicator lamp ON.
EXTERIOR LAMP BATTERY SAVER CONTROL
With the combination switch (lighting and turn signal switch) in the 2nd position and the ignition switch is
turned from ON or ACC to OFF, the battery saver feature is activated.
Under this condition, the headlamps remain illuminated fo r a period of time, unless the lighting switch position
is changed. If the lighting switch position is changed, then the headlamps are turned off.
AUTO LIGHT SYSTEM
AUTO LIGHT SYSTEM : System DiagramINFOID:0000000009463545
AUTO LIGHT SYSTEM : System DescriptionINFOID:0000000009463546
• BCM (Body Control Module) controls auto light operati on according to signals from optical sensor, lighting
switch and ignition switch.
• IPDM E/R (Intelligent Power Distribution Module Engine R oom) operates parking, license plate, tail, front fog
lamps and headlamps according to CAN communication signals from BCM.
• Optical sensor detects ambient brightness of 800 to 2,500 lux. And optical sensor converts light (lux) to volt-
age, then sends the optical sensor signal to BCM.
OUTLINE
The auto light control system has an optical sensor that detects outside brightness.
When the lighting switch is in AUTO position, it autom atically turns ON/OFF the parking, license plate, tail,
front fog lamps and headlamps in accordance with the am bient light. Sensitivity can be adjusted. For the
details of the setting, Refer to BCS-19, "HEADLAMP : CONSULT Function (BCM - HEADLAMP)"
