TIRE PRESSURE MONITORING SYSTEM (TPMS) WARNING LIGHT DIAGNOSTIC PROCEDURE

This bulletin has been amended. Please discard previous versions.

APPLIED VEHICLES:

All Infiniti vehicles with Tire Pressure Monitoring System (TPMS)

IF YOU CONFIRM

Page 143

The TPMS warning light is illuminated (continuously or flashing)

ACTIONS

STEP 1: Turn ignition to "OFF" and then "ON" position (engine not required to be running).

^ If the TPMS warning light is continuously illuminated (not flashing) the TPMS is operating normally and has detected low tire pressure in one of

the tires. Go to STEP 2.

NOTE:

> Normal tire pressure maintenance is not covered under warranty.

> Some 2011 and newer models will display an alert in the Vehicle "CHECK TIRE information display near the speedometer. The alert will

read "Check Tire PRESSURE Pressure" or similar and will accompany the illuminated TPMS light.

^ If the TPMS warning light is flashing for approximately one minute there is a TPMS system malfunction. Do not go to Step 2. Instead check the

DTC and refer to the Service Manual for repair instructions.

STEP 2: Leave the ignition in the "ON" position* (engine is not required to be running) and set the tire pressure to the recommended pressure.

^ Refer below for Important Tire Pressure Information.

* Leaving the ignition in the ON position may allow the TPMS to detect the corrected tire pressure more quickly on 2009 and newer models

(WITHOUT having to drive the vehicle).

Important Tire Pressure Information:

Each vehicle is equipped with a "Tire and Loading Information" placard (see example in Figure 1).

For factory equipped tires follow the recommended code pressure on the placard to set the tire pressure on the vehicle.

Tire pressure can be affected by factors such as tire temperature, outside temperature, time and altitude.

^ Refer to ITB08-015 for additional information about these factors that affect tire pressure including seasonal temperature changes.

When tire pressure is low make sure it is not caused by a leak. If needed repair as necessary.

After tires are inflated to the recommended pressure the vehicle may need to be driven at speeds above 16 mph for the TPMS to turn off the low tire

pressure warning light. DO NOT USE CONSULT TO RESET THE TPMS.

For additional Tire Pressure Information refer to ITB08-015 (Tire Pressure Information).

AUTO LOCK/UNLOCK FUNCTION

APPLIED VEHICLES: All 2010-2012 Infiniti vehicles equipped with power door locks

SERVICE INFORMATION:

For testing purposes, both the auto-lock function and the auto-unlock function can be disabled or enabled independently of each other. Vehicles are

shipped from the factory with both features enabled.

The following information will confirm normal auto-lock and auto-unlock function and provide direction on how to temporarily disable and then

re-enable both of these features.

NOTE: Some models may have additional functions that can only be changed with CONSULT. This bulletin only covers those features that can be

changed without CONSULT.

FUNCTION DESCRIPTION:

> Auto-lock with speed: All doors lock automatically when the vehicle speed reaches 15 mph. (24 km/h)

> Auto-unlock: All doors unlock automatically when the ignition is placed in the OFF position (models with Intelligent Key system) or when the

key is removed from the ignition switch (models without Intelligent Key system).

If there is a concern about how either of these functions operates:

1. Make sure that power locks work properly (confirm by pressing power lock and unlock switches)

2. See the procedures below to test the Auto-lock/unlock modes independently. Modes can also be tested with CONSULT. Refer to the appropriate

section of the Electronic Service Manual (ESM) for additional information.

Page 141

IMPORTANT: After testing or service, both auto-lock and auto-unlock features must be re-enabled before a vehicle is returned to the customer.

MODE CHANGE TEST PROCEDURE:

To change the AUTO-UNLOCK mode for testing purposes, perform the following procedure:

a. First, close all doors.

b. Then place the ignition switch in the ON position,

c. And do the following within 20 seconds of performing Step b:

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.

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:

^ 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.
