TPMS Diagnostic Chart

CAUTION:

^ Do NOT remove the Long Term Storage Fuse unless the ignition key is inserted in the ignition switch.

^ If the storage fuse is removed without the ignition key in the switch, the engine will not start.

^ To correct this condition if it occurs, first insert the fuse, then insert the key in the ignition switch.

^ See the Service Manual for more information.

IMPORTANT INFORMATION:

I.D. Registration:

310

^ This process informs or tell the control unit of each wheel transmitter's location (i.e. LF, RF, RR, and LR).

^ Reason: The control unit must know the location of each transmitter in order to correctly relay (send) pressure information about each tire/wheel.

Transmitter "Wake Up" Activation:

^ Turns on ("Wakes Up" each wheel transmitter allowing it to send pressure information to the control unit.

The chart shows some conditions which may require I.D. Registration and/or Transmitter "Wake Up" Activation.

NOTES:

1) In the case of a low tire pressure condition the TPMS warning light will come on. To turn the light OFF do the following:

^ Pump up the tire pressure to the correct setting.

^ Drive the vehicle over 20 MPH for several minutes.

2) Tire pressure signals from the wheel transmitters are updated by the control unit as follows:

Vehicle parked with ignition switch ON

^ Pressure information updated every hour*

Vehicle driven over 20 MPH

^ Pressure information updated every minute*

* When the ignition is first turned "ON", CONSULT-II will indicate "0" pressure and will not give an update for 1 hour. To save time

drive the vehicle over 20 MPH for a few minutes. The pressure information will then be updated.

SERVICE PROCEDURE

Wheel Transmitter Activation ("Wake Up") Procedure

This procedure must be performed using the TPMS Initialization Tool # J-45295.

IMPORTANT INFORMATION! DURING THIS ACTIVATION PROCEDURE:

^ Do NOT remove the Long Term Storage Fuse (also known as the "Electronic Parts Fuse").

^ Do NOT turn the ignition switch to the OFF position.

^ If you do either of the above all four wheel transponders will have to be re-activated.

1. Make sure the batteries in the TPMS Initialization Tool # J-45295 are in good strong condition. If needed use a tester to check battery

condition.

311

2. Confirm the Long Term Storage Fuse is installed in the vehicle's fuse panel (see Figure 2).

3. Turn the ignition switch to the ON position.

IMPORTANT:

The wheel transmitters must be activated in the order shown in Figure 3.

312

4. Position the TPMS Initialization Tool on the tire and center it with the valve stem (see Figure 4). NOTE: Do NOT touch the wheel with the

TPMS Initialization Tool.

5. Press the button on the TPMS Initialization Tool and hold the tool in position until the vehicle parking lights flash twice*.

^ This could take up to 15 seconds.

^ The parking lights* flash to confirm the wheel transmitter (the one you're working on) is activated.

* Except G35 Sedan and Coupe. The G35 Sedan and Coupe will sound horn only.

6. Perform step 5 on the remaining wheel transmitters in the order shown in Figure 3.

7. Confirm the TPMS warning light turns OFF after the last wheel transmitter is activated.

8. Turn the ignition key OFF then ON and confirm the TPMS Warning Light does the following:

^ Comes ON for 1 second then

^ Turns OFF and stays OFF

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.

106

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锟斤拷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.

^ 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锟斤拷F after sitting in the shop.

^ Ambient temperature outside the shop is 30锟斤拷F or will soon fall to 30锟斤拷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:

107

^ 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:

^ 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.

INFINITI; TIRE ROTATION AND DIAGNOSIS OF THE LOW TIRE PRESSURE WARNING SYSTEM (LTPWS)

This bulletin amends ITB04-009. Please discard all earlier versions.

APPLIED VEHICLES:

All Infiniti vehicles with the Low Tire Pressure Warning System

SERVICE INFORMATION

When doing a tire rotation on a vehicle with the Low Tire Pressure Warning System (LTPWS) please note:

^ "ID registration" of the LTPWS is not required.

For 2004 G35 Sedan and Coupe (V35, CV35)

^ In the Electronic Service Manual (ESM) for the Above Vehicles on pages WT-13 and WT-14 it says that you need to perform ID registration

when the tires are rotated. This is not the case. As stated above, ID registration does not have to be done when rotating the tires.

^ Future amendments to these ESMs will have this change made.

IMPORTANT NOTE ABOUT LTPWS SELF-DIAGNOSIS AND CONSULT-II

Remember as stated in the ESM:

^ The first step when performing LTPWS Self-Diagnosis is to perform transmitter ID registration.

^ This is critical or the actual malfunction location may be different from that displayed on CONSULT-II.
