Electrical - JIS/CCA Battery Testing Information
Classification: EL10-001
Reference: ITB10-021
Date: March 11, 2010
INFINITI; TESTING JIS-TYPE & CCA-TYPE BATTERIES
APPLIED VEHICLES: All Infiniti vehicles
SERVICE INFORMATION
Infiniti vehicles equipped with standard lead/acid batteries use one of two different types with unique battery rating specifications: JIS & CCA.
^ JIS = Japan Industrial Standard, used for Japan produced batteries
^ CCA = Cold Cranking Amps, standard for North American produced batteries
IMPORTANT:
^ JIS batteries have different testing specifications than CCA batteries.
^ If you must use the GR8 Battery Tester in a mode other than MODEL mode, JIS Mode MUST ALWAYS BE USED for JIS batteries otherwise an
incorrect result will occur. NEVER test a JIS battery using the CCA test in the GR8; the test software in the GR8 is different for JIS and CCA
modes. ANY CCA value you may have for a JIS-type battery is inaccurate for testing purposes.
ALWAYS test with the GR8 using the MODEL mode (if available).
^ Selecting MODEL and vehicle type will automatically select the proper JIS or CCA value for the Original Equipment battery.
^ If the applicable vehicle is not listed, update the GR8 to make sure it has the most recent data package.
^ If the applicable vehicle still is not listed:
1) Determine which type of battery (CCA or JIS) is installed in the vehicle. .
2) Select CCA or JIS in the GR8 based on the type of battery installed.
Determine the Battery Type
Batteries with JIS (Japanese Industrial Standard) Number
Page 222
^ Batteries installed in vehicles produced in Japan have a JIS number embossed in the plastic on top of the battery.
^ These vehicles have a VIN that begins with the letter "J".
Batteries with CCA (Cold Cranking Amps) Number
^ Batteries installed in vehicles produced in North America have a CCA number displayed on the label attached to the top of the battery.
^ These vehicles have a VIN that begins with a number: 1, 3, or 5.
Selecting CCA or JIS in the GR8 Battery Tester
Vehicles with JIS Battery
^ Select JIS, then choose the option that matches the first five (5) characters of the JIS number on the battery.
NOTE:
DO NOT select CCA when testing a JIS battery.

Tire Monitor System - Tire Pressure Info.
Classification: WT08-004C
Reference: ITB08-015C
Date: October 3, 2011
TIRE PRESSURE INFORMATION FOR VEHICLES WITH TPMS
The publication data on this bulletin has been amended to include newest models.
APPLIED VEHICLES:
All Infiniti vehicles with Tire Pressure Monitor System (TPMS)
SERVICE INFORMATION
The Low Tire Pressure Warning Lamp will illuminate (steady not flashing) if the tire pressure is low in any of the four road tires.
^ This is not an indication of a malfunction. Rather it is a signal to the driver that the tire pressure in the vehicle must be adjusted.
Tire pressure must be adjusted/corrected at or above the pressure shown on the TIRE AND LOADING INFORMATION label before the Low Tire
Pressure Warning Light will go OFF.
^ Regular tire pressure maintenance such as described in this bulletin is not covered under the warranty.
The air pressure inside a tire can change due to several factors such as:
^ Seasonal temperature change
^ Tire temperature change due to driving
^ Natural pressure loss over time
Compensate for the above temperature factors when adjusting and setting tire pressure.
Each vehicle is equipped from the factory with a TIRE AND LOADING INFORMATION label.
This label lists the COLD tire pressure setting for the original tires on the specific vehicle.
NOTE:
Tires are considered COLD after the vehicle has been parked for 3 or more hours or driven less than 1 mile at moderate speeds.
When setting / adjusting tire pressure, make sure to use an accurate tire pressure gauge.
Use the following information for reference:
Temperature:
^ Tire pressure changes approximately 0.8 psi for every 10��F of temperature change. As temperature decreases, pressure decreases.
^ Tire pressure may change 3 - 5 psi between a Cold reading and a reading taken just after the vehicle has been driven for several miles.
Page 145
^ Seasonal temperature change can result in tire pressure that is low enough to turn on the Low Tire Pressure Warning Light.
Example 1 - Seasonal Temperature Change:
^ The temperature of the vehicle is 70��F after sitting in the shop.
^ Ambient temperature outside the shop is 30��F or will soon fall to 30��F due to seasonal change.
^ Recommended pressure on the TIRE AND LOADING INFORMATION label is 35 psi.
^ The tire pressure should be compensated an additional +3 psi and adjusted to 38 psi to avoid dropping below the label value when the vehicle
experiences cooler ambient air temperature.
^ Compensation should also be used in the PDI process as needed.
Example 2 - WARM Tires:
^ A vehicle arrives to the dealer after being driven across town.
^ The WARM tire pressure reading is 32 psi.
^ Recommended COLD tire pressure on the TIRE AND LOADING INFORMATION label is 35 psi.
^ The tire pressure should be compensated an additional +3 psi and adjusted to 38 psi to avoid dropping below the label value when the tires cool.
Natural tire pressure loss overtime:
^ Vehicle tire pressure can naturally decrease by approximately 1.0 - 1.5 psi per month. This will vary due to seasonal temperature change.
^ After 6 to 8 months tire pressure may be low enough to turn ON the Low Tire Pressure Warning Light.
High Altitude
^ At high altitude locations a standard tire pressure gauge may show the tire pressure higher than the TPMS system. If the gauge reading is not
accounted for this could result in turning ON the Low Tire Pressure Warning Light.
^ Standard tire pressure gauge readings increase about 1.0 psi for every 2,200 ft of altitude increase above sea level (up to 10,000 ft). See Graph 3.
^ For example if the TIRE AND LOADING INFORMATION label reads 33 psi then at an elevation of 5,280 ft, the cold inflation pressure using a
gauge should be increased 2.5 psi to 35.5 psi."
NOTE:
In the above example, C-III, Signal Tech II, or the vehicle information display (if equipped) would show a tire pressure of 33 psi. If needed use
C-III or Signal Tech-II to confirm tire pressure.
NOTE:
Page 146
^ After correcting the tire pressure the vehicle may need to be driven at speeds above 16 mph to activate the TPMS and turn off the low tire pressure
warning light.
^ If pressure compensation for temperature is used, the pressure should be re-checked and adjusted at a later time when the tires are cold.
^ If after turning the ignition ON, the TPMS light flashes for one minute and then turns solid, refer to ITB10-023 or ITB09-050.

A/T - 7 Speed A/T Fluid Color/Refilling Information
Classification: AT11-008
Reference: ITB11-036
Date: June 16, 2011
INFINITI; INFORMATION FOR 7 SPEED ATF
APPLIED VEHICLES:
All Infiniti vehicles with 7 Speed A/T using Nissan Matic S ATF
SERVICE INFORMATION
When inspecting or servicing an Infiniti 7 speed transmission you may find that the fluid color is darker than expected. In the first 2,000 to 3,000
miles of operation, the fluid (Nissan Matic S - 999MP-MTS00P) will become darker in color than new fluid.
Page 152
The photo in Figure 1 shows an example of fluid darkening after 3,500 miles of operation in a 7 Speed transmission.
^ This fluid darkening is a normal condition.
^ The fluid does not need to be changed because of the darkening.
The fluid's lubrication properties and quality are not diminished because of the darkening.
NOTE:
The Infiniti 7 Speed A/T requires Special Tool J-49829 for transmission fluid fill and level check. The level check procedure is included in this
bulletin.
ATF Level Check

1. Park the vehicle on a lift and set the parking brake.


2. Connect CONSULT III (C-III) to the vehicle.


3. With C-III monitor ATF temperature.

NOTES:
> ATF temperature must be maintained at 95-113��F (35-45��C) during ATF level check.
> If the ATF temperature is above 113��F stop the engine to allow the ATF to cool down.

1. Once the ATF temperature reaches approximately 104��F (40��C) or below start the engine and let idle.


2. Shift the shift selector lever (shift lever) in each gear position and then return to Park.


3. Raise the vehicle on the lift.

NOTE:
Leave the engine idling. If the engine is turned off, the ATF fluid level will be adjusted well below the proper level.
Page 153
7. Remove the overflow plug from the transmission pan (see Figure 1).
^ Have a drain pan positioned under the overflow plug hole.
^ At first an initial amount of fluid may come out. This does not mean the transmission is full.
NOTE:
The engine MUST BE IDLING the whole time during the fluid level check. If the engine is turned off, the ATF fluid level will be adjusted well
below the proper level.
IMPORTANT:
In order to make sure the transmission is full; you must overfill the transmission and then let the excess drain out from the overflow plug hole.

1. Connect the Transmission Fill Pump at the overflow plug hole (see Figure 2).


2. Pump in approximately 2 liters (about 2 quarts) of Nissan Matic S ATF.

10. Disconnect the Fill Pump hose at the quick disconnect (see Figure 2).
^ If a steady stream of fluid drains out go to the next step.
IMPORTANT:
The amount of fluid that drains out should be enough so that it is obvious the fluid was overfull and is now draining to the correct level.
NOTE:
The engine MUST BE IDLING the whole time during the fluid level check. If the engine is turned off, the ATF fluid level will be adjusted well
below the proper level.
^ If little or no fluid drains out repeat Step 8 and 9.
11. Allow fluid to drain from the overflow tube until it is just a drip.
Page 154
NOTE:
Check to make sure the fluid temperature is still in specified range (35-45��C 95-113��F).
12. Install a new overflow plug. This completes the ATF level check.
^ Torque the filler plug to 12.4 Nm (1.3 kg-m, 9 ft lb).
Refill After Draining / Removing the Pan
1. With the pan and drain plug installed connect the Transmission Fill Pump at the overflow plug hole and then fill the pan with approximately 4
liters (about 4 US quarts) of Nissan Matic S ATF.
2. Perform ATF Level Check starting.
