2019 MAZDA MODEL CX-30 dead battery

Please note that the TPMS is not a
substitute for proper tyre
maintenance, and it is the driver's
responsibility to maintain correct tyre
pressure, even if under-inflation has
not reached the level to trigger
illumination of the TPMS low tyre
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 tyre pressure
telltale. When the system detects a
malfunction, the telltale will 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 tyre pressure as
intended. TPMS malfunctions may
occur for a variety of reasons,
including the installation of
replacement or alternate tyres or
wheels on the vehicle that prevent
the TPMS from functioning properly.
Always check the TPMS malfunction
telltale after replacing one or more
tyres or wheels on your vehicle to
ensure that the replacement or
alternate tyres and wheels allow the
TPMS to continue to function
properly.
¾To avoid false readings, the system
samples for a little while before
indicating a problem. As a result it
will not instantaneously register a
rapid tyre deflation or blow out.▼If there is a problem with the Tyre
Pressure Monitoring System
(TPMS)
If the TPMS warning light flashes, there
may be a problem with the system.
Consult an expert repairer (we
recommend an Authorised Mazda
Repairer) to have the system inspected.
Refer to Tyre Pressure Monitoring
System (TPMS) Warning Indication/
Warning Light (Flashing) on page
7-57.
In the following cases, the system
cannot recognise the tyre pressures
correctly and the TPMS warning light
may flash.
xThere is equipment or a device
nearby emitting radio signals the
same as a tyre pressure sensor.
xA metallic object such as a
non-genuine electronic device is
installed near the centre of the
instrument panel (obstructs the radio
signals from the tyre pressure sensors
to the receiver).
xA device such as one of the following
is used in the cabin.
xElectronic devices such as a
computer.
xConverter devices such as a
DC-AC converter.
xThere is a large accumulation of
snow or ice around the vehicle tyres.
xThe battery in a tyre pressure sensor
is dead.
xA wheel not equipped with a tyre
pressure sensor is used.
xTyres employing steel in the sidewall
of the tyre are installed.
xTyre chains are used.
▼When a tyre pressure decreases
If the TPMS warning light turns on, a
tyre pressure may be low. Inspect the
