ATBS Technology SC MS33 Users Manual

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.

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.
