the vehicle, it needs to be used together with the receiver. 
1. 安装方式 Installation 
Sensors are mounted on the hub of the vehicle to measure tire pressure and temperature. 

2. 功能特性 Functional characteristics 
The sensor has 24 -hour uninterrupted monitoring function, which is mainly divided into storage 
mode, normal mode and matching mode. 
Storage mode: When the battery of the tire pressure monitoring sensor is powered on, the 
sensor will be initialized immediately, and then enter this mode, waiting to be loaded into the tire 
and given pressure; When the pressure is greater than 70kPa, the sensor will enter normal mode. 

Normal mode: When the tire pressure monitoring sensor detects a pressure greater than 70kPa, 
the sensor will enter normal mode. 
Matching mode: The sensor is triggered using a handheld tool to allow the receiver to learn the 
sensor information or state. 
3. 报警类型 Classes of alarm 
Low pressure alarm: tire pressure received by the tire pressure receiver ≤75%* standard 
pressure. 
Ultra-low pressure alarm: tire pressure receiver received tire pressure value ≤50%* standard 
pressure. 
High pressure alarm: Tire pressure receiver received tire pressure value ≥130%* standard 
pressure. 
Quick leak alarm: 
The tire pressure monitoring sensor measures the tire pressure every 4s, and the pressure drop 
value within 12S is ≥30kPa. It sends a CAN message to the instrument and records the 
corresponding fault code. Until the next cycle measurement value < 30kPa rapid gas leakage 
situation is eliminated, stop the alarm. 
Temperature alarm 
When the tire temperature received by the tire pressure receiver is ≥90 ℃ (CAN be set), the CAN 
message is sent to the instrument and the corresponding fault code is recorded at the same time. 
Stop the alarm until the tire temperature is less than 90 ° C.
