Nissan Quest E52. Manual - part 1255

WT-4

< PRECAUTION >

PRECAUTIONS

• ID registration is required when replacing or rotating wheels, replacing tire pressure sensor or BCM. Refer to

WT-23, "Work Procedure"

.

• For easy fill tire alert function, refer to the following.
- When inflating the tires, park the vehicle in the safe area and ensure the safety of the working area.
- Read and understand the easy fill tire alert function prior to use.
- Inflate the tires one at a time.
- If there is no response for approximately 15 seconds or more after inflating the tires, cancel the use of the

easy fill tire alert function or move the vehicle approximately 1 m (3.2 ft) backward or forward to try again.
The air filler pressure may be weak or out of service area.

- Despite the high-precision TPMS pressure sensor, an indicated value may differ from that of the pressure

gauge.

- Air pressure is measured rather high due to the rise in tire air temperature after driving.
- If TPMS is malfunctioning, the easy fill tire alert is unusable.
• Replace grommet seal, valve core and valve cap of tire pressure sensor in TPMS, when replacing each tire

by reaching the wear limit. Refer to 

WT-48, "Exploded View"

.

• Because the tire pressure sensor conforms to North America radio law, the following items must be

observed.

- The sensor may be used only in North America.
- It may not be used in any method other than the specified method.
- It must not be disassembled or modified.

Service Notice and Precautions for Road Wheel

INFOID:0000000009653411

• Genuine NISSAN aluminum wheel is designed for each type of vehicle. Use it on the specified vehicle only.
• Use Genuine NISSAN parts for the road wheels, valve caps and wheel nuts.
• Always use them after adjusting the wheel balance. For the balance weights, use Genuine NISSAN alumi-

num wheel weights.

• Use caution when handling the aluminum wheels, because they can be easily scratched. When removing

dirt, do not use any abrasives, a wire brush, or other items that may scratch the coating. Use a neutral deter-
gent if a detergent is needed.

• After driving on roads scattered with anti-icing salts, wash off the wheels completely.
• When installing road wheels onto the vehicle, always wipe off any dirt or foreign substances to prevent them

from being trapped between the contact surfaces of wheel.

• Never apply oil to nut and bolt threads.
• When tightening the valve cap there is a risk of damaging the valve cap if a tool is used. Tighten by hand.

BCM

INFOID:0000000009653415

• The BCM reads the air pressure signal received by the tire pressure receiver, controls the low tire pressure

warning lamp, hazard warning lamp, and horn operation. It also has a judgment function to detect a system
malfunction.

• Controls easy fill tire alert function. Refer to

Tire Pressure Sensor

INFOID:0000000009653416

The tire pressure sensor integrated with a valve is installed on a wheel, and transmits a detected air pressure
signal by radio wave. 

Tire Pressure Receiver

INFOID:0000000009653417

• Tire pressure receiver is incorporated into remote keyless entry receiver.
• The tire pressure receiver receives the air pressure signal transmitted by the tire pressure sensor in each

wheel.

Information Display

INFOID:0000000009653418

The vehicle information display is shown when a low tire pressure warning lamp signal is transmitted from
BCM to combination meter. via CAN communication.
