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.



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



3. 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.



7. 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.

P0152



P0132, P0152 A/F SENSOR 1



Description



The air fuel ratio (A/F) sensor 1 is a planar one-cell limit current sensor. The sensor element of the A/F sensor 1 is composed an electrode layer,



which transports ions. It has a heater in the element.



The sensor is capable of precise measurement = 1, but also in the lean and rich range. Together with its control electronics, the sensor outputs a



clear, continuous signal throughout a wide range.



The exhaust gas components diffuse through the diffusion layer at the sensor cell. An electrode layer is applied voltage, and this current relative



oxygen density in lean. Also this current relative hydrocarbon density in rich.



Therefore, the A/F sensor 1 is able to indicate air fuel ratio by this electrode layer of current. In addition, a heater is integrated in the sensor to



ensure the required operating temperature of approximately 800锟紺 (1,472锟紽).



DTC Logic

DTC Logic



DTC DETECTION LOGIC



When a misfire occurs, engine speed will fluctuate. If the engine speed fluctuates enough to cause the crankshaft position (CKP) sensor signal to



vary, ECM can determine that a misfire is occurring.



The misfire detection logic consists of the following two conditions.



1. One Trip Detection Logic (Three Way Catalyst Damage)



On the 1st trip when a misfire condition occurs that can damage the three way catalyst (TWC) due to overheating, the MIL will blink.



When a misfire condition occurs, the ECM monitors the CKP sensor signal every 200 engine revolutions for a change.



When the misfire condition decreases to a level that will not damage the TWC, the MIL will turn off.



If another misfire condition occurs that can damage the TWC on a second trip, the MIL will blink.



When the misfire condition decreases to a level that will not damage the TWC, the MIL will remain on.



If another misfire condition occurs that can damage the TWC, the MIL will begin to blink again.



2. Two Trip Detection Logic (Exhaust quality deterioration)

REMOVING FOREIGN MATERIAL FROM THE WINDSHIELD



APPLIED VEHICLES: All Infiniti



SERVICE INFORMATION



Windshield "foreign material" that is on the surface of the glass in some cases can be cleaned off with a very particular type and grade of steel wool.



^ Most any foreign material on the surface of the Windshield can be cleaned off by using #0000 super fine steel wool.



> The #0000 grade super fine steel wool can be found in most hardware stores.



^ In most cases the glass cannot be damaged by manually rubbing (no power tools) too hard or too much and it is recommended not to use any



cleaners with the steel wool.



Use new steel wool from an un-opened bag and store unused portion in a re-sealable container to prevent contamination.



^ Do not use dirty or contaminated steel wool. Dirty or contaminated steel wool will scratch the glass. If the steel wool is dropped on the floor get a



new piece of steel wool to clean the windshield.



^ Clean (then dry) windshield first with soap and water to remove any abrasive dirt or grit that may be present before using steel wool.



NOTE:



Always try and clean any windshield surface issue first with #0000 grade super fine steel wool before glass replacement is considered.



CLAIMS INFORMATION



Foreign material on the windshield surface is not a warrantable condition.



Materials used to clean the windshield, such as the steel wool mentioned above, are considered a shop supply.

SERVICE INFORMATION



To improve customer satisfaction by providing the correct repair on the first visit, Nissan has revised the procedure for ordering an "exchange" or



"new" Audio Visual (A/V) Control Unit for vehicles with the premium navigation systems only (see PROCEDURE).



^ To ensure a proper diagnosis and repair, the technician will need to call TECH LINE to confirm (or assist with) their diagnosis and the proper



repair prior to ordering the unit.



^ Clarion will require a confirmation from TECH LINE prior to shipping the exchange unit orders.



^ For the premium navigation system only.



^ Parts will be put on parts restriction and will need to be cleared prior to the order shipping.



^ The warranty claims call center will verify that TECH LINE has recommended replacement as part of the approval process in the event that a new



unit is required.



> TECH LINE has the support of engineering and Clarion in diagnosis if required.



NOTE:



All other A/V units will be ordered and shipped through the normal process.



> As usual, most units ordered should be an exchange unit versus a new unit.



This requirement of calling TECH LINE for confirmation to replace an A/V unit will be monitored to ensure the most effective and accurate method



of repair. Future changes or adjustments may be made to this process to increase repair timeliness and/or customer satisfaction.



A NEW UNIT IS REQUIRED ONLY IF:



^ The vehicle has not yet been sold.



^ The customer requests a new unit on a Non-warranty repair.



^ The exchange unit is not available.



^ Insurance claim replacement.



NOTE:



Nissan would also recommend that this procedure is used for non warranty repairs to ensure that a proper diagnosis and repair are performed.
