Tires - Mounting Information/Precautions
Classification: WT 11-004
Reference: ITB11-022
Date: March 21, 2011
TIRE MOUNTING INFORMATION
APPLIED VEHICLES: All Infiniti
SERVICE INFORMATION
^ When mounting tires to wheels it is important that the tire bead is seated correctly.
^ A tire bead that is not seated correctly may cause a vehicle vibration.
^ High performance tires and tires with shorter sidewalls (low aspect tires) may require more care to make sure the tire bead is seated correctly.
^ Follow the Tire Mounting Tips in this bulletin.
Tire Mounting Tips:
NOTE:
Page 193
These tips are not intended to be a complete instruction for mounting tires to wheels. Make sure to read and follow the instruction for your specific
tire service equipment.
1. Clean the tire bead with an approved rubber cleaning fluid.
^ Rubber cleaning fluid is a locally sourced common product used in the tire service process.

1. Clean the wheel (flange and bead seat area), see Figure 2. Make sure to clean off all rust and corrosion.


2. Apply an approved tire lubricant to the tire and wheel in the areas shown in Figures 1 and 2.

^ Tire lubricant is a locally sourced common product used in the tire service process.
Tire:
^ Apply lube to the inner bead only, of both beads.
^ Do not apply lube to the flange area (outer bead area)
NOTE:
Too much tire lubricant may allow the tire to slip on the rim while driving. If this occurs, the tire may become un-balanced.
Wheel:
^ Apply lube to the Safety Humps and Bead Sealing area.
^ Do not apply lube to the flange area.
4. Before inflating the tire:
Page 194
^ If there are "match-mount" marks on the tire and rim, align the marks.
^ Make sure the tire is evenly positioned on the lower safety humps.
5. WARNING: Do not exceed the tire manufactures recommended bead seating inflation pressure. Generally this is 40psi.
If the bead does not seat with the appropriate pressure:
a. Break down the tire/rim assembly.
b. Re-apply lubricant as shown in Figures 1 and 2 above.
c. Remount the tire.
6. After inflating the tires inspect the bead area.
^ Make sure bead is seated uniformly (the same) around the entire circumference of the wheel.
Page 195
NOTE:
Many tires have Aligning Rings that will help confirm the bead is uniformly seated.
If uniform; bead is seated correctly.
If not uniform;

1. Break down the tire/rim assembly.


2. Re-apply lubricant as shown in Figures 1 and 2.


3. Remount the tire.


4. After the tire/wheel is balanced, apply an index mark to the tire at the location of the valve stem (see Figure 6).

^ This index mark will allow you to tell if the tire has slipped on the rim (see Figure 7).
Tire to Rim Slippage:
^ Too much tire lubricant may allow the tire to slip on the rim while driving. If this occurs, the tire may become un-balanced.
^ Overtime the tire lubricate will dry, eliminating the lubricant as a cause of tire slippage.
^ Some tire lubricants may require up to 24 hours to completely dry.
^ If slippage occurs, the tire/wheel will need to be re-balanced.

Classification: ST08-002E
Reference: ITB08-046E
Date: November 21, 2011
DIAGNOSIS OF VEHICLE PULL (DRIFT) AND STEERING WHEEL OFF CENTER
The "Refer to General Procedures" in this bulletin have been amended. Please discard previous versions of these General Procedures.
APPLIED VEHICLES: All Infiniti
SERVICE INFORMATION
Page 112
If a customers reports their "vehicle pulls" or the "steering wheel" is off-center use the Diagnostic Flow Chart above and the other information in this
bulletin to diagnose and correct the issue.
Road Test
Determine if the vehicle has a pull or steering wheel off-center issue that requires repair.
IMPORTANT:
^ If the vehicle has any tire issues such as:
> Tires that are different sizes (except when specified from the factory)
> Significant difference in the amount of wear between any of the tires
> Any other tire irregularity or damage to any tire
Replace the tire(s) or use known good tires from another vehicle for all road tests and diagnostics in this bulletin.
^ Make sure tire pressure is set to the correct specification.
1. Install the following measuring tools on the vehicle:
^ Steering Wheel Offset Gauge
^ Road Crown Gauge
Page 113
Page 114
NOTE:
Refer above for a description of these tools and an explanation of their use.

1. Obtain a watch with a second hand (preferably a stopwatch) to use during the road test.


2. Take the vehicle for a road test and confirm the customers concern.

^ Select a flat road where the vehicle can be driven in a straight line at a preferred speed of 60 mph.
^ During the road test make sure the vehicle is pointing straight. Don't worry about steering wheel position during the road test.
NOTE:
^ If you adjusted the tire pressure or changed the tires before the road test the issue may have been resolved.
^ If there are cross winds strong enough to affect the vehicle straight line movement then diagnosis cannot be performed.

1. Determine the vehicles issue - refer to the definitions of Pull and Steering Wheel Off-center below.


2. When the road test is completed remove the Road Crown Gauge; leave the Steering Wheel Off-Set Gauge in place until the Service Procedure is

complete.
6. Refer to the Flow Chart above.
Page 115
Other Service Information
Customers may report that their vehicle's steering wheel is "off-center" because the steering wheel spokes are tilted to the left or right when the
vehicle continues straight ahead on a straight flat road (see example in Figure 1).
If a vehicle's steering wheel spokes are slightly off-center while driving straight it may be the normal result of road crown. Most roads in the United
States are built with a "crown" to help rain water drain from the road surface. The slope of the road crown varies from place to place.
Vehicles have a natural tendency to drift to the low side of the crown. The greater the slope of the crown the faster the vehicle will drift in that
direction.
Tires and vehicles are designed to counteract the effect of typical road crown but may not fully counteract the effect of a highly crowned road.
Some freeways slope to both the left and right from the center. When driving on a freeway that slopes in both directions a vehicle may exhibit a
small amount of drift to the left when driving in the left lane and a small amount of drift to the right when driving in the right lane.
This bulletin does not address road crown issues because they are not vehicle related, although the customer may incorrectly perceive them to be.
Description/Definition of Steering Wheel "Off-center" Condition
The steering wheel spokes are tilted to the left or right 2 mm or more (see example in Figure 2) when driving straight ahead on a straight flat road.
^ When driving straight on a highly crowned road the steering wheel may be turned (off-center) to counteract the affect of the road crown. When
road testing for an off-center condition the vehicle should be driven on a straight flat road.
^ Although the vehicle does not pull in either direction the customer may perceive that the vehicle pulls because it will respond if he or she tries to
bring the steering wheel back to center. This condition can occur if the tie rod length is uneven (not adjusted correctly) from side to side.
Description/Definition of a Vehicle "Pull" Condition
The vehicle consistently drifts to one side while driving at a constant speed on a straight flat road.
Page 116
^ A vehicle is said to "pull" if it completes a lane change in less than 7 seconds (with no steering correction from the driver) when driving at 60
MPH on a road with less than 2 degrees of road crown slope. All four wheels must pass into the other lane during this time (7 seconds).

Paint - Paint Swells/Discolored Under Paint Guard Film
Classification: BT99-032F
Reference: ITB99-043F
Date: February 11, 2011
PAINT SWELL/STAIN/SPOT UNDER PAINT GUARD FILM
This bulletin has been amended. All current production models have been applied and the company contact information has been updated. Please
discard all previous versions.
APPLIED VEHICLES: All Infiniti Production Models with Paint Guard Film
SERVICE INFORMATION
NOTE:
Failure to follow the procedures in this bulletin may result in the denial of a warranty claim.
In an effort to protect the paint finish Paint Guard Film (PGF) is applied on many new Infiniti vehicles.
Paint Guard Film is a temporary white plastic protective film that is applied by the factory to the horizontal painted surfaces of the vehicle. The PGF
protects the paint finish during vehicle handling transportation and storage from harmful elements such as acid rain iron particles bird droppings tree
sap and other environmental contaminants.
NOTE:
Paint Guard Film CANNOT remain on the vehicle for more than six months after the vehicle's manufacture date. PGF must be removed at the end of
six months.
Page 198
If an Infiniti vehicle exhibits swelling stains or spots on the paint finish (which appear milky or whitish on dark colored vehicles and dark-shaded or
coffee-colored on light colored vehicles) immediately after the PGF is removed the cause may be moisture collection under pockets/creases of the
PGF. The paint may absorb moisture which may cause the affected paint finish area to temporarily discolor.
The size of the swell stain or spot may range from a dime to a clinched fist and have an irregular shape and possibly a slightly raised surface.
This incident may occur anywhere under the PGF but may be noted in particular to occur around the windshield fluid nozzle (see Figure 1) and on
the deck lid. In any case use the following service procedure to correct the incident.
IMPORTANT:
If this condition occurs, do not rebuff or initially attempt to repaint the effected area. Perform the following service Procedure first.
SERVICE PROCEDURE
Use one of the following procedures to remove the moisture from the effected area(s).
Place Vehicle in Sun Light (warm weather)
In warm weather place the vehicle in the sun light. The paint condition should disappear in a few hours depending on the severity of the condition.
Place Vehicle Indoors (cold weather)
In cold weather place the vehicle indoors at a temperature of approximately 70��F. The paint condition should disappear in about 8 to 12 hours
depending on the severity of the condition.
Heat Lamp or Heat Gun
To speed up the recovery process of the condition use a portable infrared heat lamp or a heat gun. Follow the Important Points listed below when
using a heat lamp or a heat gun.
CAUTION:
Only an experienced paint technician who is familiar with paint temperature limitations should use a heat lamp or heat gun. Also do not use a heat
lamp or heat gun on painted plastic body components (i.e. bumper covers spoilers etc.).
Important Points
^ The maximum total bulb wattage for the infrared heat lamp should not exceed 750 watts.
^ The heat gun wattage should be between 1200 and 1400 watts.
Page 199
^ Maintain the heat lamp/heat gun distance so the painted surface temperature is between 175�� and 190��F (80�� - 90��C). Affix a paper label
thermometer on the paint surface two inches away from the effected area (see Figure 2) to monitor the surface temperature.
NOTE:
Paper label thermometers can be purchased from the company listed below.
^ Do not apply the heat gun for more than 5 minutes as permanent damage (i.e. bubbling burns etc.) can occur to the paint.
^ Do not hold the heat gun closer than 12 inches from the paint surface. Also do not hold the heat gun in one position rather move it continuously
from side to side to heat the affected area evenly.
^ Do not apply heat directly on to the paper label thermometer as this will give a false temperature reading.
This repair is effective only if performed within a short time period after the PGF is removed from the vehicle i.e. a few days in mild climates or
within a week in colder climates. This repair will not be effective beyond that time frame.
If the condition does not disappear after the above service procedures are performed the condition may be permanent and the effected area may have
to be re-painted.
Paper thermometers may be purchased from the company listed below.
NOTE:
Equivalent paper thermometers may be used and are available from other local suppliers.

Emissions - System Readiness Test (SRT) Drive Patterns
Classification: EC98-002E
Reference: ITB98-011E
Date: November 7, 2012
SYSTEM READINESS TEST (SRT) DRIVE PATTERNS
This bulletin has been amended. Several Changes were made at "Step 7: Confirm All SRTs "COMPLETE"."
APPLIED VEHICLES: 1996 and newer Model Years as required by State Emissions Inspections Regulations.
SERVICE INFORMATION
As part of an enhanced emissions test for Inspection & Maintenance (I/M) some States may require the System Readiness Test (SRT) status be
checked.
^ The SRT is used to indicate whether the engine control module (ECM) has completed self diagnosis of major emissions systems and components.
^ In these instances the State may require completion of the SRT before permitting the emissions inspection to proceed.
The State Emissions Inspection Station may advise an Infiniti customer to return to the dealership for service due to one or more SRT items coming
up "INCOMPLETE." Use the information in this Bulletin to help you "COMPLETE" the SRT.
^ In most cases the ECM will automatically complete its self diagnosis cycle during normal vehicle usage and the SRT status will indicate
"COMPLETE" for each applicable system.
^ Once indicating "COMPLETE" the SRT status remains "COMPLETE" until the Self Diagnosis memory is erased.
^ Occasionally certain portions of the self diagnostic test may not be completed as a result of the customers normal driving pattern. In these cases
the SRT will indicate "INCOMPLETE" for these items.
NOTE: The SRT will also indicate "INCOMPLETE" if:
^ The self diagnosis memory is erased for any reason or
^ The ECM memory power supply is interrupted for several hours.
This bulletin contains information to help you perform a comprehensive road test (Drive Pattern) that enables the ECM to complete the SRT.
^ A separate Drive Pattern sheet for each 1996 and 1997 vehicle variation is included with this Bulletin.
^ For 1998 and newer vehicles refer to the EC section of the appropriate Service Manual for the required Drive Pattern. They are listed under On
Board Diagnostic> System Readiness Test.
NOTE:
You must select the Drive Pattern that correctly corresponds with all variables for the vehicle being serviced (i.e. model model year engine emissions
certification transmission powentrain and for 1996/1997 models ECM part number.
NOTE:
To ensure all ECM Self Test requirements are met it is important to drive the entire Drive Pattern even if only one SRT item indicates
"INCOMPLETE."
CLAIMS INFORMATION:
Refer to the current Warranty Flat Rate Manual for claims information.
Service Procedure
Page 12
SRT WORKFLOW
Step 1: Check for DTC
1. Use a CONSULT tool to check for any stored DTCs.
^ If any DTCs are stored they must be repaired at this time.
^ Refer to ASIST for diagnostic and repair information.
NOTE:
Normal warranty coverage will apply for DTC repairs.
2. If no DTCs are stored go to the next step.
NOTE:
DO NOT touch Erase or you will lose previously completed SRTs.
Step 2: Check SRT Status
Page 13
Check the SRT Status (Complete or Incomplete).
^ Use the appropriate CONSULT tool.
^ For older vehicles a Generic Scan Tool may be needed to check SRT status.
NOTE:
In some cases the normal driving that occurs between the time the vehicle was referred by the State Emissions Inspection Station and it is
brought into the dealership for SRT evaluation may allow the ECM to complete the SRTs. If this occurs no further action is necessary.
Always check SRT status before performing the SRT Drive Pattern.
Step 3: Identify the Vehicle
You must select the Drive Pattern that correctly corresponds with all variables for the vehicle being serviced refer to image below:
Step 4: Obtain ECM Part Number (1996 and 1997 models only)

1. Use a CONSULT tool to obtain the ECM part number.


2. Write the ECM part number in the space provided above.

Page 14
3. Compare the vehicles ECM part number with the list of ECM part numbers provided in the Infiniti SRT System Chart above to determine the
Drive Pattern for the vehicle being inspected.
NOTE:
For 1996 and 1997 models; if the vehicles ECM part number does not match a part number listed on the SRT System Chart for that vehicle
either 1) the vehicle was identified incorrectly or 2) the vehicle has the wrong ECM installed. The SRT cannot be completed with the
incorrect ECM.
Step 5: SRT Road Test (perform Drive Pattern)
To properly obtain SRT readings of "COMPLETE" it is necessary to drive the vehicle under the exact conditions required by the vehicle's
ECM.
Be sure to select the correct Drive Pattern. The SRTs will not complete if the wrong drive pattern for that vehicle is used.
1. Select the Drive Pattern based on the Vehicle Identification (see Step 3).
^ For 1996 and 1997 vehicles:
> This bulletin contains a specific Driving Pattern for every 1996 and 1997 Infiniti vehicle.
> Use the Bookmark on the left side of the ASIST screen to choose the correct model and year.
> Verify that the vehicle ECM P/N matches EXACTLY an ECM P/N listed on the Drive Pattern sheet you chose.
> Print the Drive Pattern to take with you.
^ For 1998 and newer vehicles refer to the EC section in the appropriate Service Manual for the required Drive Pattern. It is listed under
On-Board Diagnostics> System Readiness Test.
> Print the Drive Pattern to take with you.
Page 15
2. Prior to driving the vehicle review the Drive Pattern and prepare to complete it from start to finish:
^ Review the Pre-Check items listed on the drive pattern and ensure all conditions are met.
^ Determine the vehicle speeds required by the drive pattern.
^ Plan your route to minimize traffic and traffic signals that might interrupt the Drive Pattern tasks.
^ Review the Drive Pattern section(s) that must be restarted if you are interrupted.
^ Do not use the ASCD (cruise control) during any section of the Drive Pattern that contains the "No ASCD symbol."
^ Some EVAP-equipped vehicles will require that fuel be added to the tank between the first and second trip. Be prepared to purchase fuel
or plan your route to accommodate this step.
^ For these EVAP-equipped vehicles begin the road test with less than 1/2 tank of fuel. If the fuel level is greater than 1/2, more time may be
required to complete the EVAP sections of the Drive Pattern and you may not be able to add fuel as required.
3. Review the Drive Pattern for any input signals that need to be monitored during the drive.
^ If needed, Connect a CONSULT tool to the vehicle to monitor required signals.
NOTE:
^ Monitor the Fuel Temperature if the EVAP SRT is "INCOMPLETE." One part of the EVAP SRT diagnostic logic requires a 3��C
increase in fuel temperature from the time the ignition key is turned to ON as part of the test criteria. Fluctuations in the fuel
temperature reading can extend the time required for the EVAP SRT to indicate "COMPLETE." If the fuel temperature change is not
sufficient after completing the SRT Drive pattern idle the vehicle until a fuel temperature increase of at least 3��C is noted or until the
EVAP SRT indicates "COMPLETE."
^ If the fuel temperature increases 3��C or more but the SRT still indicates "INCOMPLETE" the SRT Drive Pattern may need to be
repeated.
4. Note the following items before starting the Drive Pattern:
IMPORTANT:
Nissan requires using a driver and an assistant to conduct SRT driving patterns. The assistant should read the Drive Pattern CONSULT
data and drive time and convey driving instruction to the driver. It is the drivers responsibility to observe and react to traffic conditions.
Always drive the vehicle in a safe manner and obey all traffic laws.
^ To ensure all ECM Self Test requirements are met, drive the ENTIRE pattern whenever any SRT items indicate "INCOMPLETE."
^ Some vehicles require that sections of the Drive Pattern be driven two times to satisfy the "self diagnosis two trip logic." For vehicles
that require two trips the pre-check engine coolant temperature must be met before beginning Section 1 of the second trip.
5. Perform the Drive Pattern:
a. Make sure all Pre-Check conditions are met.
b. Drive the vehicle and carefully follow the specific instructions and time requirements listed in each section of the Drive Pattern.
NOTE: If you monitor the (B/FUEL SCHDL):
^ The Base Fuel Schedule (B/FUEL SCHDL) is an indication of engine load.
^ It will be easier to match high B/FUEL SCHDL values when driving up slight hills in the recommended gear range.
^ It will be easier to match low B/FUEL SCHDL values when driving down slight hills in the recommended gear range.
^ Turning the A/C compressor ON will increase the B/FUEL SCHDL value while turning it OFF will decrease the B/FUEL SCHDL value.
Step 6: Recheck for DTC
Upon completion of the Drive Pattern determine if any DTCs have been stored. Only in rare cases will this occur.
^ If a DTC has been stored after completing the Drive Pattern it must be repaired. Refer to ASIST for diagnostic and repair information.
NOTE: Normal warranty coverage will apply for DTC repairs.
^ Once the DTC is repaired, erase the stored DTC. Turn the ignition OFF for 10 seconds, and then repeat the entire Drive Pattern (Step 5) to
Page 16
"COMPLETE" the SRTs.
^ If no DTCs have been stored DO NOT touch "Erase" or all SRT items will reset to "INCOMPLETE."
Step 7: Confirm All SRTS "COMPLETE"
If all SRT items indicate "COMPLETE" the inspection is complete.
^ If Catalyst and/or 02 Sensor Monitors show "INCOMPLETE" perform step A or B below.
A. Check Self Learning Value and A/F ALPHA. If either value is + 10% or more above target of 100%, clear Self Learning Value.
^ Perform DTC diagnosis for P0171 or P0174 and check for the following possible causes:
> Intake air leaks
> Front heated oxygen sensors
> Injectors
> Exhaust gas leaks
> Incorrect fuel pressure
> Lack of fuel
> Mass airflow sensor
A. Check Self Learning Value and A/F ALPHA. If either value is -10% or more below target of 100% clear Self Learning Value.
^ Perform DTC diagnosis for P0172 or P0175 and check for the following possible causes:
> Intake air leaks
> Front heated oxygen sensors
> Injectors
> Exhaust gas leaks
> Incorrect fuel pressure
> Lack of fuel
> Mass airflow sensor
^ After repairs have been made, run the prescribed drive pattern and check that A/F ALPHA is within +/- 10% of the target of 100%
during the steady state portions of the drive cycle. If it is not, then continue repairs. If it is return to STEP 5.
