MS33 sensor Introduction
1. Introduction
This MS33 BLE sensor is a type of sensor that combined
TPMS and App installed in smart phone called Nissan
ETCM. MS33 TPMS internal sensor adapts BLE low
energy transmission, let driver understand tire situation
through Nissan ETCM. When the system detects tire
pressure or temperature abnormal situation, it (APP) will
directly alarm the driver. Besides, transmission between
sensor and smart phone has been fully protected by a
well-design encryption/ decryption design. It could
provide the condition of sensor let people who with bad
intention know. Further more, there is an auto-learning
function in Nissan ETCM. All the thing need to do is to
place the smart phone in front of the driver at the left
hand side, then drive for a while. There are more
explanation about how to comply the whole process of
auto-learning position function.
About This Manual：
The information in this manual is subject to change
2.4 Balance the wheels.
2.5 Install the wheel to appropriate position of the
vehicle.
Note：
(1) Beware of the conductivity between the
sensor and valve stem.
(2) Sensors are supposed to be well locked valve
stem to avoid from leaking.
(3) Please replace original manufacturer’s
sensor battery in case voltage is below 2.7v.
(4) Sensor will transmit data every 28~32
without notice.
This manual has been created with extra care. In case
that you have any comments or questions regarding
this manual, please contact your local dealer or our
Customer Service Center.
Before operating this set, please fully understand the
prerequisite such as specifications or constraints of

seconds when the vehicle is running, and
when the vehicle stops, the sensor will
transmit data every 148~152 seconds.
3. Nissan ETCM APP Installation:
Nissan ETCM App is designed for Nissan Vehicle.
Through the Nissan ETCM you can know tire
temperature and pressure, sensor battery voltage, and
each sensor’s ID. At the meanwhile, it provide the autolearning position function for the driver to save time to set
Sensor ID. Besides, the connection between MS33 BLE
sensors has been encrypted, it could increase the safety
and the stabilization of data transmission.
3.1 Install APP (Take Android as example)
3.1.1 Download the APP: Nissan ETCM from Apple Store
or Google Play.
3.1.2 Turn on the APP and agree the statement.
3.1.4: Turn on the Bluetooth, and it will scan the devices
automatically.
3.1.3 Choose Sedan icon on the screen.
3.1.5 The BLE icon will light on after turning the Bluetooth
on the main page

3.2 App Auto Operating
For the sensor side, there are 2 way to awake the
transmission. First, using the function of auto-learning
position to pair the sensor and APP by reliable algorithm.
Place reference procedure 3.2 series Second, using
trigger to awake MS33 properly, and then enter the
sensor ID setting pages. After setting the ID properly, it
will read the tire data immediately.
3.2.1 Click “Learning ID” button below
3.2.3 Please the smart phone in front of the driver at the
front center side, then drive for about 20 to 30 minutes.
3.2.2 Press the “Auto” button, start to learn the sensor ID
automatically, at the meanwhile, the vehicle will start to
blink.
3.2.4 During the detection, the sensor ID will show on the
learning page automatically, once it complete the
detection, the learning page will show like the below
picture. Then, please press “Save” button to turn the
page to the main page

3.2.5 Press “Yes” button to confirm.
3.3.2 ID Edit Mode page: User could key in the sensor ID
one by one directly. Once four sensors are already,
please press “Save” button to store the ID.
Note: When the Auto Sensor ID Learning is abnormal,
please stay in the same learning page and redo 3.2
procedure again.
3.3 App Manual Operating
3.3.1Enter learning ID page, users can use “edit” or “QR
code” button to set up the ID manually before install
inflate the tire.
QR Code Mode page: User could scan the QR Code on
the MS33 to get the sensor ID one by one directly. . Once
four sensors are already, please press “Save” button to
store the ID.
