sensor MAZDA MODEL 6 2020 (in English) Repair Manual

As an added safety feature, your vehicle has been equipped with a tire pressure monitoring
system (TPMS) that illuminates a low tire pre ssure telltale when one or more of your tires is
significantly under-inflated. Accordingly, when th e low tire pressure telltale illuminates, you
should stop and check your tires as soon as possible, and inflate them to the proper
pressure. Driving on a significantly under-in flated tire causes the tire to overheat and can
lead to tire failure. Under-inflation also reduce s fuel efficiency and tire tread life, and may
affect the vehicle's handling and stopping ability.
Please note that the TPMS is not a substitute for proper tire maintenance, and it is the
driver's responsibility to maintain correct ti re pressure, even if under-inflation has not
reached the level to trigger illumination of the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when
the system is not operating properly.
The TPMS malfunction indicator is combined with the low tire pressure telltale. When the
system detects a malfunction, the telltale wi ll flash for approximately one minute and then
remain continuously illuminated. This sequence will continue upon subsequent vehicle
start-ups as long as the malfunction exists. When the malfunction indicator is illuminated,
the system may not be able to detect or signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of reasons, including the installation of replacement
or alternate tires or wheels on the vehicle th at prevent the TPMS from functioning properly.
Always check the TPMS malfunction telltale after replacing one or more tires or wheels on
your vehicle to ensure that the replacement or alternate tires and wheels allow the TPMS to
continue to function properly.
 To avoid false readings, the system samples for a little while before indicating a problem. As
a result it will not instantaneously regi ster a rapid tire deflation or blow out.
▼System Error Activation
When the warning light flashes, there may
be a system malfunction. Consult an
Authorized Mazda Dealer.
A system error activation may occur in the
following cases:
When there is equipment or a device
near the vehicle using the same radio
frequency as that of the tire pressure
sensors.
When a metallic device such as a
non-genuine navigation system is
equipped near the center of the
dashboard, which may block radio
signals from the tire
pressure sensor to
the receiver unit.
When using the following devices in the
vehicle that may cause radio
interference with the receiver unit.
A digital device such as a personal
computer.
A current converter device such as a
DC-AC converter.
When excess snow or ice adheres to the
vehicle, especially around the wheels.
When the tire pressu re sensor batteries
are exhausted.
When using a wheel with no tire
pressure sensor installed.
When using tires with steel wire
reinforcement in the sidewalls.
When using tire chains.

▼Tires and Wheels
CAUTION
When inspecting or adjusting the tire air
pressures, do not apply excessive force to
the stem part of the wheel unit. The stem
part could be damaged.
Changing tires and wheels
The following procedure allows the TPMS
to recognize a tire pressure sensor's unique
ID signal code whenever tires or wheels
are changed, such as changing to and from
winter tires.
NOTE
Each tire pressure sensor has a unique ID
signal code. The signal code must be
registered with the TPMS before it can
work. The easiest way to do it is to have
an Authorized Mazda Dealer, change your
tire and complete ID signal code
registration.
When having tires changed at an
Authorized Mazda Dealer
When an Authorized Mazda Dealer,
changes your vehicle's tires, they will
complete the tire pressure sensor ID signal
code registration.

When changing tires yourself
If you or someone else changes tires, you
or someone else can also undertake the
steps for the TPMS t
o complete the ID
signal code registration.
1. After tires have been changed, switch
the ignition ON, then back to ACC or
OFF.
2. Wait for about 15 minutes.
3. After about 15 minutes, drive the vehicle at a speed of at least 25 km/h
(16 mph) for 10 minutes and the tire
pressure sensor ID s ignal code will be
registered automatically.
NOTE
If the vehicle is driven within about 15
minutes of changing tires, the tire pressure
monitoring system warn ing light will flash
because the sensor ID signal code would
not have been registered. If this happens,
park the vehicle for about 15 minutes,
after which the sensor ID signal code will
register upon driving the vehicle for 10
minutes.
Replacing tires and wheels
CAUTION
 When replacing/repairing the tires or
wheels or both, have the work done by
an Authorized Mazda Dealer, or the tire
pressure sensors may be damaged.
 The wheels equipped on your Mazda are
specially designed for installation of the
tire pressure sensors. Do not use
non-genuine wheels, otherwise it may
not be possible to inst all the tire pressure
sensors.
Be sure to have the tire pressure sensors
installed whenever tires or wheels are
replaced.
When having a tire or wheel or both
replaced, the follow ing types of tire
pressure sensor installations are possible.
The tire pressure sensor is removed
from the old wheel and installed to the
new one.

The same tire pressure sensor is used
with the same wheel. Only the tire is
replaced.
A new tire pressure sensor is installed to
a new wheel.
NOTE
The tire pressure sensor ID signal code
must be registered when a new tire
pressure sensor is purchased. For
purchase of a tire pressure sensor and
registration of the tire pressure sensor
ID signal code, consult an Authorized
Mazda Dealer.
When reinstalling a previously removed
tire pressure sensor to a wheel, replace
the grommet (seal between valve body/
sensor and wheel) for the tire pressure
sensor.

Parking Sensor System*
The parking sensors use ultrasonic sensors which detect obstructions around the vehicle
when the vehicle is driven at lo w speeds, such as during garage or parallel parking, and a
buzzer sound and detection indicator notify the driver of the a pproximate distance from the
vehicle to the surrounding obstruction.

Do not rely completely on the parking sensor system and be sure to confirm the safety around
your vehicle visually when driving:
This system can assist the driver in opera ting the vehicle in the forward and backward
directions while parking. The detection ranges of the sensors are limited, therefore, driving the
vehicle while relying only on the system may cause an accident. Always confirm the safety
around your vehicle visually when driving.
NOTE
Do not install any accessories within the detection ranges of the sensors. It may affect the
system operation.
Depending on the type of obstruction and th e surrounding conditions, the detection range
of a sensor may narrow, or the sensors may not be able to detect obstructions.
The system may not operate norma lly under the following conditions:
Mud, ice, or snow is adhering to the sensor area (Returns to normal operation when
removed).
The sensor area is frozen (Returns to normal operation when the ice is thawed).
The sensor is covered by a hand.
The sensor is excessively shocked.
The vehicle is excessively tilted.
Under extremely hot or cold weather conditions.
The vehicle is driven on bumps, inclines, gravel, or grass covered roads.
