REMOVAL AND INSTALLATION
Transmitter (Pressure Sensor) INFOID:0000000004307341
REMOVAL 1. Remove wheel and tire using power tool.
2. Deflate tire. Unscrew transmitter retaining nut and allow transmitter to fall into tire.
3. Gently bounce tire so that transmitter falls to bottom of tire. Place wheel and tire assembly on tire changing machine and
break both tire beads. Ensure that the transmitter remains at the
bottom of the tire while breaking the bead.
4. Turn tire so that valve hole is at bottom, and gently bounce the tire to ensure transmitter is near valve hole. Carefully lift tire onto
turntable and position valve hole (and transmitter) 270 degrees
from mounting/dismounting head.
5. Lubricate tire well, and remove top side of tire. Reach inside the tire and remove the transmitter.
6. Remove the second side of the tire as normal.
INSTALLATION 1. Place first side of tire onto rim.
2. Apply suitable silicone lubricant to new transmitter seal then install seal on transmitter. Refer to MA-14 .
NOTE:
Always replace the seal after every disassembly.

REMOVAL AND INSTALLATION
3. Mount transmitter on rim and tighten nut. NOTE:
Make sure no burrs exist in the valve stem hole of the wheel.
4. Place wheel on turntable of tire machine. Ensure that transmitter is 270 degrees from mounting/dismounting head.
NOTE:
Do not touch transmitter with mounting head.
5. Lubricate tire well, and install second side of tire as normal. Ensure that tire does not rotate relative to rim.
6. Inflate tire and balance the wheel and tire assembly. Refer to WT-7, " Balancing Wheels " .
7. Install wheel and tire assembly in appropriate wheel position on vehicle. Refer to WT-7, " Rotation " .
NOTE:
If replacing the transmitter, then transmitter wake up operation
must be performed. Refer to WT-13, " Transmitter Wake Up Operation " .

PRECAUTION
SERVICE INFORMATION
PRECAUTION
Precaution for Supplemental Restraint Syst em (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER" INFOID:0000000004306902
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. 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 w hether 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 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 SRS 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.
Precaution for Procedure without Cowl Top Cover INFOID:0000000004306903
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc. PIIB3706J

FRONT WIPER AND WASHER SYSTEM
Component Parts and Har ness Connector Location INFOID:0000000004306904
System Description INFOID:0000000004306905
• Front wiper relays (front wiper relay, front wiper hi gh relay) are located in the IPDM E/R (intelligent power
distribution module engine room).
• Wiper switch (combination switch) is composed of a combination of 5 output terminals and 5 input terminals.
Terminal combination status is read by BCM (body control module) when switch is turned ON.
• BCM controls front wiper LO, HI, and INT (intermittent) operation.
• IPDM E/R operates wiper motor accordi ng to CAN communication signals from BCM.
OUTLINE
Power is supplied at all times
• to ignition relay, located in IPDM E/R, from battery directly,
• through 40A fusible link (letter g, located in fuse and fusible link box)
• to BCM terminal 70,
• through 30A fuse (No. 39, located in IPDM E/R)
• to front wiper relay located in IPDM E/R
• through 15A fuse (No. 52, located in IPDM E/R), and
• through 20A fuse (No. 53, located in IPDM E/R)
• to CPU located in IPDM E/R.
When ignition switch is in ON or START position, power is supplied
• through ignition relay (located in IPDM E/R)
• to front wiper relay (located in IPDM E/R), and 1. IPDM E/R E45, E46 and E48 2. BCM M18 and M20 (view with glove
box removed)3. Front wiper motor E1
(view with cowl
top cover removed)
4. Front and rear washer motor E2 (view with front bumper fascia re-
moved) 5. Combination switch (wiper switch)
